They don’t know each other, but they have much in common:

They’re both from small towns — Masure from St. Johnsbury, Vt., Payne from Hanover, Va. They used to steal beers from their dads before branching out into a variety of drugs.

They have been "clean" for three years, thanks in part to several 12-step program meetings each week. And they’re both preaching what they practice by working for organizations that offer support to people and families struggling with addiction.

Their stories touch upon themes made clear recently by scientists searching for answers about the genesis and treatment of addiction. The questions have plagued researchers for decades, but only in the past several years have they had the tools — such as technology that provides a real-time view of brain function — to unravel them.

The 2004 National Survey on Drug Use and Health found that of Americans 12 and older, nearly 8.4 million were addicted to alcohol and nearly 5 million were addicted to other drugs. About 1.4 million were addicted to both, according to the survey by the federal Substance Abuse and Mental Health Services Administration.

Thanks to advances in neurobiology, "we have enormous knowledge now of what’s going on" in addicts’ brains, says George Koob, professor of molecular integrative neuroscience at the Scripps Research Institute in La Jolla, Calif. Koob, who calls himself an "irrepressible optimist," says he is hopeful that new insights into the mechanisms of addiction will lead to new treatments and reduced suffering.

They might debate the terms used to describe addiction, but top scientists in the field pretty much agree on what it is.

"The inability to stop is the essence of what addiction is," says Nora Volkow, director of the National Institute of Drug Abuse, part of the National Institutes of Health. As Payne, 27, puts it, "my favorite drug was more and all."

That’s not to say that people who can’t make it through the day without latte grandes or Ghirardelli chocolate are addicts, says Volkow, a self-professed "chocoholic" who has pioneered brain-imaging studies of addiction. Caffeine does activate some of the same brain circuits as the drugs of addiction, but only very mildly, she says. Caffeine can be habit-forming, but Starbucks devotees won’t risk jail time or divorce to feed their habit.

Nor is addiction the same as dependence, although the American Psychiatric Association’s diagnostic manual says it is, says Volkow, who’s pushing to drop that wording. "Addiction is much harder to treat. Everybody given an opiate (such as morphine) will become physically dependent, but not everybody will become an addict."

WorldWideAddiction.com — Substance Addiction has been recognized "officially" as a disease for many years now, but there is still a great deal of ignorance on the subject -even amongst the medical profession.

Addicts/alcoholics (people tend to separate the two, but from here on in I will use the term "addict" to cover the broad range of substance abusers) are seen as weak people with no will-power.

Want to know what will-power is?

It is waking up in the morning, so nauseous that you race to the bathroom and don’t know which end to use first! After that initial wake-up purge, you then make your way shivering and shaking into the kitchen and drink an open, flat, warm beer that has a cigarette butt floating in it. Or because you are shaking so much, you drink that warm white wine that has been sitting out all night, through a straw since you can’t hold a glass! You do this, choking back the bile that is rising in your throat, because you know that the only way to begin functioning again on some sort of level is to try and build up the alcohol in your system before you take a seizure.

Do you think drinking methylated spirits at 5am in the morning is an easy thing to do?

I have known many addicts whose veins in their arms and legs are so damaged, that they inject themselves in their eyeballs. Because going without their "hit" is a far worse option.

Addicts have plenty of will-power…….

…it’s just focused in the wrong direction. Recovery teaches them us to refocus energy.

Back to the disease concept. Addiction is classified as a disease because it meets the criteria of all other terminal diseases:

- It has pattern of symptoms which are similar across all types of substance abuse

- It is a chronic condition. It doesn’t go away.

- It is progressive. Addiction only gets worse with continued use, and ends with death.

- The person is subject to relapse. In Australia, 66% of addicts who are lucky to live long enough to make it to detox will eventually die as a direct result of the disease.

- It is treatable. Here’s the good news, while substance addiction is a terminal illness, its progression can be arrested at almost any stage. But if you are seeking treatment, it is of the utmost importance that you gain medical advice. Sudden withdrawal, even from "socially acceptable" drugs such as alcohol, can cause death through seizures and coma.

It is crucial that you consult with a medical practitioner that understands addiction and withdrawal. Some well meaning, but uneducated doctors will prescribe large amounts of unsuitable medications that can lead to cross-addiction. This happened to me at one stage, and made a difficult situation worse. If you are addicted to one drug, the likelihood of becoming addicted to others is extremely high.

Wherever possible, detoxification is best carried out in a detox unit, where there is 24 hour patient care. There are a number of these units around the world, and in some cases (especially in Australia) there is no charge for this care.

When world governments begin to understand that the cost in providing this care free of charge is far outweighed by the benefits to society, we will begin to see an incredible drop in poverty, violence and divorce. The cost in providing this care will also be offset by the decrease in need of other hospitalization. 1 in 3 hospital beds in Australia are taken up by people with conditions that can be directly linked to drug abuse. At best, the world health systems overall are only currently providing band-aid solutions to one of the greatest scourges of mankind.

Are you thinking of getting help for yourself or a loved one?… do it now … for tomorrow may be too late. 

If you had terminal cancer, would you do anything about it? 

Substance addiction is a far worse disease in my opinion -it not only destroys the person, but everyone around them.

To those who helped me all those years ago -doctors, nurses, friends and strangers – even though I may not have been appreciative at the time….. my sincerest thank you. My life means something now.

Addiction is a disease, not just a state of mind.

Cocaine and methamphetamine are two drugs that are often linked together because they produce similar effects and because they belong to the same class of drugs called psychostimulants. In addition, they both have the potential for causing dependence and abuse which further strengthens the bond associate between them. Though there are many similarities, a fair number of differences do also exist, which will be discussed here.
 

Where Do They Come From?
 

Methamphetamine is man made, while cocaine is derived from the coca plant.
 

Is There A Difference in the Way They Are Used?
 

Both can be smoked, injected intravenously or snorted. The difference being that methamphetamine can be taken in pill form. In addition, cocaine can be used medically as an anesthetic and as an appetite stimulant while methamphetamine has no proven medical use.

Where and By Whom Are the Drugs Used?
 

Out of the two drugs, Methamphetamine has a much more defined area of use as well as stereotype of user. Statistics show that use of methamphetamine is highest in western areas of California, Honolulu, Hawaii, and western areas of the continental United States. Urban areas of California, Oregon, Arizona, Colorado and Washington, show increased use of methamphetamines. In recent years however, use of methamphetamine has increased in rural and urban areas of the South and Midwest.
 

Cocaine use varies so there is no geographic pattern that clearly delineates where the drugs are used. Cocaine use however, is usually significantly higher in large cities and metropolitan areas as opposed to non-metropolitan areas.
 

A possible reason for the difference between cocaine and methamphetamine addiction by area is that in rural areas, cocaine is not as easily accessible. Methamphetamine however, can be made in a garage or basement with household products, making it quite easy for individuals to make their own high.
 

Do They Produce The Same Effects?
 

* Perhaps the reason why cocaine and methamphetamines are confused is because both produce a very well received rush almost immediately. This is followed by feelings of extreme happiness or euphoria which is referred to as a rush.
 

* Methamphetamine’s high can last from eight to twenty four hours and fifty percent of the drug is removed from the body in twelve hours. Cocaine’s high on the other hand, lasts from twenty to thirty minutes and fifty percent of the drug is removed from the body in one hour.
 

* Both cocaine and methamphetamine, when injected intravenously or smoked, can cause an almost immediate rush which is followed by a high.
 

* When ingested nasally, which is referred to as snorting, neither methamphetamine nor cocaine cause a rush or a high. A similar effect is produced when methamphetamine is ingested orally.

Are the Physiological Effects Similar?
 

* Both methamphetamine and cocaine can cause immediate effects of irritability, anxiety, increased heart rate, blood pressure, body temperature and possible death. Methamphetamine’s and cocaine’s short-term effects also can include increased activity, respiration, and wakefulness, and decreased appetite.
 

* Chronic use of cocaine or methamphetamine can cause dependence and possibly stroke.
 

* In either case, cocaine or methamphetamine can lead to psychotic behavior. These behaviors are characterized by hallucinations, paranoia, violence, and mood disturbance.
 

* Some data suggests that violence is more common among methamphetamine users than among cocaine users. Drug craving, paranoia, and depression can occur in addicted individuals who try to stop using either methamphetamine or cocaine.
Is there a difference in neurotoxicity?
 

* Neurotoxicity refers to the toxic damage these drugs can incur on the brain, specifically on neuron transmission. Neurons are responsible for the processing and transferring of information. Methamphetamine can be neurotoxic in animal species ranging from mice to monkeys. Methamphetamine specifically damages neurons that produce serotonin and dopamine. Since the usual doses taken by humans are comparable to the doses causing neurotoxicity in animals, it is reasonable to believe that this also causes the same effect in humans.
 

* On the other hand, cocaine does not cause neurotoxic damage to dopamine and serotonin neurons.
 

Transmission of HIV/AIDS
 

Whether discussing methamphetamine or cocaine, a risk for HIV/AIDS still exists and must be considered when engaging in any type of sexual behavior.

Introduction
 

Cocaine is a intensely powerful addictive stimulant that acts directly on the brain. Cocaine was first extracted from the leaf of the Erythroxylon coca bush, which is endemic in South America, West Indies and Indonesia. Cocaine is one of the most commonly abused drugs and the majority of the individuals who use cocaine are also users of other drugs. The drug can generate a feeling of euphoria, hyperactivity and mental alertness. It can be rapidly highly addictive leading to relentless mental and physical problems.

The neuro-stimulating properties of the coca leaves are thought to have played some role in the development of the Inca People. Soon, the Spanish invaders quickly discovered the euphoric effects of the coca plant and introduced the plant to the Europeans, who also developed a great liking for the plant and its stimulating effects.
 

History
 

The plant was used for medicinal purposes as early as the 15th Century in Europe. In the 18th Century, concentrated forms of cocaine became available and it was soon discovered that the plant extract had some medical benefits. The drug was then widely used as a topical local anesthetic and because of its mental stimulating properties, was also used to treat depression. The use of cocaine in tonics and elixirs became widespread and it was also added to coca cola.
 

However, soon it was soon observed that drug was addictive and had profound effect on the psyche of the individual. Because of cocaine’s potent side effects, in the early part of the 20th Century, the Pure Food and Drug Act was introduced, which required that all cocaine be labeled in all medical products. However, this did not limit the use of cocaine and addiction to cocaine reached endemic proportions. In 1914, the Harrison Narcotics Act was introduced and banned the nonprescription use of cocaine products and labeled cocaine as a narcotic.
 

The Harrison Narcotics Act did nothing to diminish the use of cocaine and over the next 50 years, cocaine became the number one illicit drug used in North America. In the 70s and 80s, a new cheaper formulation of cocaine became available on the market and it has today become the favorite drug among teenagers and socially deprived individuals. By the mid-1980s, the emergency rooms were again becoming full with individuals with cocaine-related problems. Physicians again re-affirmed the abuse potential of cocaine.
 

Today, cocaine is classified as a Schedule II drug — it has towering potential for abuse and can only be administered by a doctor for legitimate medical uses. Today, the medical use of cocaine is limited to topical anesthesia of the upper respiratory tract and eye because the vasoconstrictive properties of cocaine are desirable during these procedures. However, it is not available in majority of the hospitals in North America, because safer and better agents are available.
 

Addiction Potential
 

Cocaine is an addictive psycho-stimulant with euphoric effects. The addictive properties of cocaine are thought to be due to brain dopamine D2-receptor stimulation. Dopamine is released as part of the brain’s reward system and is implicated in the high that is typical of cocaine consumption. Patient dependence depends on a number of different factors, including genetics, social and environmental factors, preexisting medical and mental conditions.

There are two fundamental forms of cocaine: powdered and "freebase." The powdered form easily dissolves in water whereas freebase is a mixture that has not been neutralized by an acid. The freebase form is usually smoked or snorted.
Warning signs of cocaine use include a change in behavior, acting isolated, careless about personal appearance, loss of interest in school, family, friends and frequently needing money. Physical exam may reveal red eyes, runny nose, frequent sniffing, change in eating and sleeping patterns and a change in friends

Cocaine induces an artificial “high” that gives its user a feeling of limitless ability and energy. When users come down, they are usually depressed, nervous, and crave for more. Todate, it has been impossible to predict who will become addicted and when the fatality will occur.
 

Frequency of Use
 

In the US, as of 2005, according to the Office of National Drug Control Policy, more than 3 million people in the United States are considered long-term cocaine users. Cocaine abuse is also widespread universally and has become a major public health issue in North America. Data suggest that the prevalence of cocaine use in the world is approximately 13 million people, or 0.23% of the global population. Cocaine use is also increasing in a number of Latin American countries, including the countries that are the main producers of cocaine.
 

All races and both genders are known to use cocaine. Individuals between the ages of 18-30 are the most frequent users. Men not only are more heavy users but also account for more overdose and toxicity from cocaine.
 

Routes of Intake
 

Cocaine may be inhaled (snorting), injected or smoked. Irrespective of the method of intake, cocaine is still a potentially deadly agent. Most individuals report that the psychotic features and habituation are more rapid and pronounced after smoking cocaine, compared to other methods. The “high” generated with smoking is instant but of a shorter duration, but the addiction potential is the same by all routes. Like all illicit drugs, injection of drugs carries with it the potential for transmission of HIV/AIDs. This becomes of more concern when the needles and other injection paraphernalia are shared.
 

A common route of transportation of cocaine is by swallowing cocaine packed in condoms. Body stuffers usually hide packages of cocaine in the rectum, vagina or mouth. These individuals usually get away until the packages rupture and cocaine intoxication becomes obvious.
 

Street cocaine is often accidentally/intentionally contaminated during the preparation process in order to dilute the cocaine used and increase profits. Commonly used cocaine adulterants may include local anesthetics, phenytoin, sugars, amphetamines, phencyclidine, phenylpropanolamine, quinine, talc, and others.
 

Mortality/Morbidity
 

Data from the Drug Abuse Warning Network (DAWN) indicate that there are about 4-5000 cocaine related deaths annually in the US. Cocaine-related deaths are rare and not always due to high dose intoxication. The lethal dose of cocaine remains unknown. Fatalities are multifactorial, and, often the cause remains unknown. Occasionally, massive exposure of cocaine occurs in body packers and results in rapid death.
 

However, the majority of cocaine users are prone to serious long term medical complications. These complications may include seizures, abnormal heart rhythms, heart attacks, stroke, blindness, liver and kidney failure, lung fibrosis and heart failure.
 

Symptoms
 

Cocaine has numerous physiological and psychological side effects. The adverse effects of cocaine’s appear almost immediately after a single dose, and fade away within a few minutes or hours. Cocaine can cause intense vasospasm of blood vessels, dilate pupils, increase the heart rate and blood pressure and can also generate a febrile response.
 

The psychological effects include euphoria, decreased fatigue, extreme hyperactivity and mental lucidity. The sense of sight, sound and touch are over amplified. During the cocaine euphoria, the need for food, sleep and personal hygiene are significantly absent. The majority of individuals report that cocaine aids them completing simple chores swiftly, whereas others experience mental confusion and are unable to carry out any tasks

The quicker the cocaine is absorbed, the more intense is the “high”, however, the duration of action is short lived. The euphoria from snorting may last 15-30 minutes, while that from smoking may last 5-10 minutes. Increased utilization can diminish the period of stimulation due to development of tolerance. High doses of cocaine and/or extended use can generate an aggressive paranoid behavior, tremors, vertigo, muscle twitches, extreme restlessness and auditory hallucinations.
 

When addicted individuals discontinue using cocaine, they frequently become depressed. This may lead to additional cocaine use to lessen the depression. Extensive cocaine snorting is known to cause ulceration of the nasal mucous membrane and even perforate the nasal septum. Cocaine-related deaths are often a consequence of cardiac arrest or seizures followed by respiratory arrest.
 

When both cocaine and alcohol are consumed, the adverse risks are increased by several folds. Combination of cocaine and alcohol in the liver is known to generate a substance called cocaethylene, which is known to potentiate cocaine’s euphoric effects and also increasing the danger of sudden death.
 

Treatment of Acute Intoxication
 

Patients with cocaine poisoning may exhibit severe CNS and cardiovascular dysfunction, leading to a loss of airway protective reflexes, cardiovascular collapse, and mortality. The goals of pharmacotherapy are to neutralize toxicity, reduce morbidity, and prevent complications.
 

The immediate control of mental agitation is critical in preventing the mortality associated with cocaine overdose. Benzodiazepines are the mainstay of therapy and may be used generously until sedation is accomplished. Avoid physical restraints in patients with psychomotor agitation because they may interfere with heat dissipation. Seizures should be aggressively treated because they may worsen hyperthermia, rhabdomyolysis, hypoxia, and acidosis. In some cases, ventilatory support and neuromuscular blockade may be required

Body packers and body stuffers may require critical care monitoring. The body packers pack their gastrointestinal tract with bags of cocaine. However, occasionally the cocaine-containing package ruptures or the packages may cause gastrointestinal obstruction.
 

All symptomatic body packers and body stuffers require intensive therapy. Charcoal may have to be introduced in the stomach to bind the cocaine and prevent absorption and surgery may be required to remove the packages.
 

Asymptomatic patients may be treated with laxatives and bowel irrigation to remove the cocaine bags. Surgical removal may also be indicated in patients with bowel obstruction.
 

Some individuals may suffer a Cocaine washout syndrome (cocaine crash syndrome) which is characterized by sudden and severe exhaustion with mental slowness, depression, suicidal ideation, anxiety and increased appetite, lasting as long as 18 hours after the last consumption. Cocaine washout syndrome is usually self-limited, and only requires supportive therapy.

Once the acute phase is stabilized, patients may require further therapy to treat the complications of cocaine. It is highly recommended that these individuals enter into a rehabilitation therapy program.
 

Treatment approaches to Addiction
 

Treatment of cocaine addicts is a multi million dollar business. Treatment programs are available throughout North America. The treatment is complex and involves changing the mind as well as altering the psychological, social, familial and environmental factors
 

Pharmacological Approaches
 

There are no approved medications currently available to specifically treat cocaine addiction. Few emerging compounds currently being investigated to assess their safety and efficacy in treating cocaine addiction include disulfiram, terguride, topiramate and modafanil. Additionally, baclofen, a GABA-B agonist, has shown promise in a few individuals who use excessive cocaine. The use of anti depressant drugs has been recommended during the early phase of cocaine abstinence, because of the moderate depression that occurs.
 

Behavioral Interventions
 

Many types of behavior therapies have been used to treat cocaine addiction, and involve both residential and outpatient approaches. Behavioral therapies are frequently the only available effective treatment for cocaine addiction. However, amalgamation of both medical and behavior treatments are more effective in the treatment of cocaine addiction.
 

Behavior therapy which has been shown to be beneficial includes vocational rehabilitation, career counseling, contingency administration and cognitive-behavioral treatment. Therapeutic communities (TCs), or residential programs with intended lengths of stay of 6 to 12 months, present another option to those in need of treatment for cocaine addiction. TCs concentrate on remobilization of the individual to society, and can incorporate on-site vocational rehabilitation and other helpful services.

Enrollment in deterrence programs, such as Narcotics Anonymous, may be of benefit for some patients.

Fox News — The U.S. leads the world in marijuana and cocaine experimentation, as well as in lifetime tobacco use, according to a survey released this week by the World Health Organization.

For the survey, which was partially funded by a division of the U.S. National Institutes of Health, researchers at the University of New South Wales in Sydney, Australia looked at drug, alcohol and tobacco use in 17 countries throughout North and South America, Europe, Asia, the Middle East, Africa and Oceania. More than 54,000 people participated in the survey.

"The United States, which has been driving much of the world’s drug research and drug policy agenda, stands out with higher levels of use of alcohol, cocaine, and cannabis, despite punitive illegal drug policies, as well as (in many U.S. states), a higher minimum legal alcohol drinking age than many comparable developed countries," the authors wrote in the study, which was published in the July 1 issue of the journal PLoS Medicine.

"The Netherlands, with a less criminally punitive approach to cannabis use than the U.S., has experienced lower levels of use, particularly among younger adults," they added.

The U.S. had the highest percentage of respondents admitting to lifetime tobacco use at 74 percent, followed by Lebanon at 67 percent, and Mexico and the Ukraine at 60 percent, according to the study.

The lowest percentages of lifetime tobacco use were found in the African countries of South Africa with 32 percent and Nigeria with 17 percent.

More U.S. respondents said they used marijuana at 42.4 percent, followed by New Zealand at 41.9 percent. Lifetime marijuana use was virtually non-existent in Asian countries, however.

Sixteen percent of U.S. survey participants said they used cocaine at least once, followed by Colombia, Mexico, Spain and New Zealand where between 4 and 4.3 percent of respondents admitted to use.

The only area where U.S. respondents trailed was in alcohol use. Almost 92 percent of U.S. respondents said they used alcohol, compared to 97 percent of Ukrainians and 95.3 percent of Germans. Just 40 percent of South African respondents used alcohol.

New York Times - According to the White House, this country is scoring big wins in the war on drugs, especially against the cocaine cartels. Officials celebrate that cocaine seizures are up — leading to higher prices on American streets. Cocaine use by teenagers is down, and, officials say, workplace tests suggest adult use is falling.

John Walters, the White House drug czar, declared earlier this year that “courageous and effective” counternarcotics efforts in Colombia and Mexico “are disrupting the production and flow of cocaine.”

This enthusiasm rests on a very selective reading of the data. Another look suggests that despite the billions of dollars the United States has spent battling the cartels, it has hardly made a dent in the cocaine trade.

While seizures are up, so are shipments. According to United States government figures, 1,421 metric tons of cocaine were shipped through Latin America to the United States and Europe last year — 39 percent more than in 2006. And despite massive efforts at eradication, the United Nations estimates that the area devoted to growing coca leaf in the Andes expanded 16 percent last year. The administration disputes that number.

The drug cartels are not running for cover.

Mexico and parts of Central America are being swept up in drug-related violence. Latin Americans are becoming heavy consumers of cocaine, and traffickers are opening new routes to Europe through fragile West African countries. Some experts argue that the rising price of cocaine on American streets is mostly the result of a strong euro and fast-growing demand in Europe.

Workplace drug tests notwithstanding, cocaine use in the United States is not falling. About 2.5 percent of Americans used cocaine at least once in 2006, the same percentage as in 2002, according to the Department of Health and Human Services.

While cocaine use has fallen among younger teenagers, 12th graders are using more: 5.2 percent used cocaine last year — up from 4.8 percent in 2001 and 3.1 percent at the low point in 1992, says a Monitoring the Future survey done by the University of Michigan.

All this suggests serious problems with a strategy that focuses overwhelmingly on disrupting the supply of drugs while doing far too little to curb domestic demand.

Washington spent $1.4 billion on drug-related foreign assistance last year — mostly to equip Colombia’s security forces and spray coca crops in the Andes. It spent another $7 billion on drug-related law enforcement and interdiction efforts at home and abroad. It spent less than $5 billion on education, prevention and treatment programs at home to curtail substance abuse.

The counternarcotics effort has produced some successes. Marijuana use in the United States has declined since 2002, the earliest year for which the government has comparable data. Teenage use of other drugs, like methamphetamine, has fallen sharply. With American aid, Colombia’s armed forces have severely weakened the FARC guerrillas, a major player in the drug trade.

The next administration should continue to help Latin American governments take on the traffickers. But it must learn from the current strategy’s shortcomings.

Eradication efforts are most likely to have more success if more money is spent on programs to wean coca growers from the business and improve the lives of their families and communities. Mexico, in particular, is in deep trouble, and the next American president should build on the Bush administration’s plans to provide counternarcotics aid. There needs to be a different mix: less money for equipment for security forces and more for economic development and programs to reform and strengthen Mexico’s judicial system.

Above all, the next administration must put much more effort into curbing demand — spending more on treating drug addicts and less on putting them in jail. Drug courts, which sentence users to treatment, still deal only with a small minority of drug cases and should be vastly expanded. Drug-treatment programs for imprisoned drug abusers, especially juvenile offenders, must also be expanded.

Over all, drug abuse must be seen more as a public health concern and not primarily a law enforcement problem. Until demand is curbed at home, there is no chance of winning the war on drugs.
