Utah — “Methamphetamine addiction has the worst long-range organic effect on the brain of any drug,” said Glen Hanson, University of Utah Addiction Center director.

Hanson’s blunt comment defines extent of the the public health problem in meth-damage control in Utah.

He was speaking at an all-day meth workshop before 30 participants; family members, caregivers and health care professionals in Roosevelt on June 21.

Addiction of any kind is a learned repetitive behavior, but meth is the worst, ” explained Hanson, “It alters the brain biology in ways similar to Alzheimer’s or Parkinson’s disease.”

Why would anyone choose to damage their brain to such a degree? The answer, because “it feels good,” may be the best an addict can offer after treatment.

Simplistic as it sounds, it is not wrong. Meth over-stimulates the “feel-good” portion of the brain and can severely damage a person’s cognitive abilities.

“The brain is a network of 100 billion cells that transmit information by making 2,000 connections individually,” Hanson said, telling the group why an addict’s ability to communicate has been compromised.

“Stimulated brain cells respond by releasing dopamine to anything that feels good” he continued. “Over-stimulated brains release too much dopamine. Then the free radicals that are chemically abundant in dopamine will eventually destroy portions of the brain.”

Meth stimulates the release of dopamine in excess. The more an addict uses the more they crave. It affects the cognition system in the brain by “turning-off” the prefrontal cortex.

As a consequence, meth addicts loose inhibitory control, tending to act on impulse rather than reason. They overreact to situations, tending toward rage.

This is partly due part to the “damage to the orbitofrontal cortex which ultimately inhibits saliency,” said Hanson. “The addict becomes motivated most by getting and using meth over anything else.”

It fouls up the meth addict’s ability to appreciate consequences like taking care of their children, themselves or being cognizant of others.

“Meth addicts may steal from or abuse their family members with little conscience,” the researcher explains. “All they think of is the drug, because the reward portion of their brain is on all the time.”

Hanson referred to the amygdala reward-region of the brain, which processes memory and emotional control. Damage to the region and the adjacent hippocampus region leaves the addict agitated and often aggressive.

Once these areas are damaged the memory portion of the addict’s brain often fails to recover even with treatment.

“Rehabilitating cognitive systems requires exercise,” explained the researcher. “Sometimes that means establishing new pathways in the brain around damaged portions that will never return.”

“Treatment is lengthy,” he continued, “requiring five to seven months for brain function to stabilize and restore saliency. It’s hardest for meth addicts because their familial support systems are often irreparably damaged. They’ve hurt the very people they need most.”

In the end, there are successful treatments to re-develop cognitive skills through mental exercise. One way, Hanson explained is through literacy education, which seems to help re-establish cognitive functions.

So, why with all this wreckage would anyone choose to use meth? Hanson’s research suggests that there is a strong sociocultural component contributing to the meth scourge in Utah.

“Meth abuse demographics indicate that it is the primary drug of choice among women,” he explained. “Thirty-seven percent of all women in treatment are addicted to meth. Men use it too, but represent fewer addicts in treatment than women.”

Some women are attracted to meth as it is readily available, cheap and long-lasting in effect. Others discover more energy, weight loss or help with social inhibitions through meth abuse.

“In Utah, there’s a sociocultural tendency of women toward perfection,” said Paul Smith, eastern Regional Director of the Division of Child and Family Services. “Perfect wife. Perfect mother. Perfect beauty. Too much pressure toward perfection drives the social component of meth abuse.”

“Whatever the cause, abuse is only part of addiction,” Hanson said. “Only 15 percent of users become severely addicted, which means 85 percent of users are out there managing their drug use.”

Why people become addicted may, in part, be genetic. For example, researchers found that many women in treatment suffer from other repetitive disorders like smoking or alcoholism.

The most interesting connection was re-occurrence of attention deficient-hyperactivity disorder. The familial connection of ADHD or alcoholism may include a predisposition toward drug addiction among family members.

There’s also the social aspect of addiction. Meth tends to stay in the family. A documentary shown at Saturday’s seminar showed women frankly admitting that, “My daughter introduced me to meth and then I gave it to my sister, and so on.”

Hanson notes that addictions like alcoholism re-occurs in families, but there is hope. Children removed from addictive families show no greater addiction rates than children from non-drug abuse families.

However, children left in addictive families are almost certainly going to experiment with drugs. Addictions, particularly those with long-term treatment requirements like meth are a burden on Utah society.

“Forty-seven percent of women in treatment for meth addiction have children,” Hanson continued. “Worse still, 45 percent of female meth addicts end up in prison. Incarcerated women cost the state $30,000 each and an additional $33,000 for each child placed in foster care. All totaled, jailed addicts cost the state about $100,000 a year.”

Treatment, on the other hand, costs the state about $15,000 per person. More recently, the treatment alternative has become policy in the criminal justice system of Utah. The effort is to stop the revolving door of prison addicts.

“New strategies for treatment are highly successful, but the addict must remain in rehabilitation,” said Hanson. “Judges are learning that success requires mandated, long-term compulsory treatment. I guess they figured that success means more taxpaying Utahns.”

BBC News — Twin research projects have offered both present and future hope to people suffering from alcohol addiction.

US researchers say that epilepsy drug topiramate boosts general health as well as cutting the craving for drink.

A UK specialist said the potential side-effects of topiramate still merited caution.

A separate project showed that a single injection of a protein into the brains of rats almost immediately stopped them wanting alcohol.

Topiramate is not licensed in the UK for the treatment of alcohol addiction, although doctors are allowed to prescribe it if they wish, and occasionally do.

The latest study results, published in the journal Archives of Internal Medicine, could increase the number of doctors willing to do this.

Researchers from the University of Virginia analysed the results of the US-wide trial, which took 371 people with a heavy drinking problem, and gave them either topiramate or a placebo "dummy" drug.

They found, that over 14 weeks, those taking topiramate not only had fewer obsessive thoughts and compulsions about using alcohol, but had generally improving health.

Their weight, cholesterol and blood pressure dropped, and levels of liver enzymes linked to "fatty liver" disease, the forerunner of cirrhosis, also fell away.

Lead researcher Professor Bankole Johnson said: "What we’ve found is that topiramate treats the alcohol addiction, not just the ’symptom’ of drinking."

Side effects

Dr Jonathan Chick, a specialist in the psychiatry of addiction, welcomed the results, particularly the figures which proved better health, rather than relying on an estimate of reduced drinking levels, which could prove misleading.

He said: "There are other drugs which were originally developed to prevent epileptic seizures, which have also shown promise in reducing relapse in alcoholism, but topiramate is so far the most convincing."

However, he said that his own limited use of topiramate had been very carefully monitored to minimise the powerful side-effects of the drug.

In the other study, the Proceedings of the National Academy of Sciences Journal reported on a study in rats carried out at the University of California at San Francisco.

The scientists injected a brain protein called GDNF directly into a part of the brain called the ventral tegmental area, which is thought to be heavily involved in "drug-seeking" behaviour.

The rats were placed in an environment designed to mimic human social drinking, with a lever that could be pushed to deliver an alcoholic drink.

Rat rehab

The protein began working almost immediately, with effects noticed within 10 minutes.

The research also suggested that other cravings were unaffected, as the rats’ desire for their supply of sugary water continued unabated.

In addition, once treated with GDNF, rats seemed to be less likely to "relapse" to alcoholism after a "rehab" situation, in which the alcohol supply was cut off for a period of time, then reintroduced.

"Our findings open the door to a promising new strategy to combat alcohol abuse, addiction and especially relapse," said lead author Dr Dorit Ron.

Dr Chick said that there had been various attempts to interfere directly with the brain systems controlling alcohol cravings, although these had only achieved "mixed success" when transferred from experimental animals to humans.

ABC NEWS — A study at the University of Western Australia has found that heroin addicts with naltrexone implants are far less likely to return to heroin use than those taking oral tablets.

But critics are sceptical about the study and say that naltrexone is still a risky option for drug users trying to kick the habit.

Naltrexone is a drug which blocks the effects of heroin on the brain. It is usually taken as a tablet, but if heroin users stop taking the pill they often fall back into drug use.

That is why scientists have been working on an implant which automatically releases naltrexone into the body.

Gary Hulse from the University Of Western Australia is confident about the naltrexone’s success.

"It means that you’ve got a a one-stop shop. People can come in, they receive their treatment or implant and for five months or six months, they carry that treatment with them," he said.

The six-month trial involved 69 heroin users. Fifty-four completed the trial. Of the 28 participants who received a naltrexone tablet, 15 returned to regular heroin use. Of the 26 people who received a naltrexone implant, just two returned to heroin use.

Researchers like Mr Hulse say it is a good result for naltrexone implants.

"This is a relatively safe and a treatment which has good clinical outcomes," he said.

The study is yet to be published in a peer-reviewed medical journal, but the team at the University of Western Australia are confident the research will be well received.

"I’m not only confident that it’ll be published in a peer review but I would be surprised if this wasn’t accepted by one of the extremely high rating journals," said Mr Hulse.

But critics like Dr Alex Wodak, from the Alcohol And Drug Services at Vincents Hospital in Sydney, have little time for the new study.

"The paper hasn’t been published yet in a scientific journal and so therefore, it’s the equivalent of hearsay in a court of law. That is, it’s not really evidence," he said.

Naltrexone is a controversial drug. The implants are yet to be approved by Australia’s Therapeutic Goods Administration (TGA) and there have been mixed results for heroin users.

Some patients have stopped using heroin after receiving an implant. But others have cut them out of their body or suffered serious side effects.

"The implants, I know for a fact, were at one stage required by the therapeutic goods administration to be stamped, not for use in human subjects, and the authors have conceded that to me in writing," said Dr Wodak.

But researchers such as Moira Sim from the Naltrexone Trial Independent Monitoring Committee say the implants used in the Perth trial were approved by the TGA.

"The committee reviewed all the processes that the trial went through and we are confident that they followed the correct processes that the data was collected properly, and therefore I’m very confident in the results of the trial," she said.

The researchers say the next step will be to conduct a trial comparing naltrexone implants with methadone and other drugs used to control heroin addiction.

Washington Post – When it comes to treatment, the experts think alcoholism needs to catch up to depression.

Three decades ago, long before the dawn of the Prozac Era, depression was a disease rarely treated in its mild form, reluctantly treated with drugs and usually treated by experts only. Today, signs of depression are actively sought, drugs are prescribed early and often, and most cases are handled by nonpsychiatrists.

With alcohol abuse, however, most physicians don’t go looking for trouble and don’t recognize it until it’s breathing in their face. Over-drinking patients often don’t think of looking for help even if they know they are heading in the wrong direction. And society as a rule looks at alcohol treatment as a last-chance, 90-degree corner taken only at high speed.

Simplify screening

All this will change if American physicians adopt the new guidelines for "Helping Patients Who Drink Too Much" promulgated by the National Institute on Alcohol Abuse and Alcoholism, part of the National Institutes of Health.

The idea is to simplify the screening for excessive alcohol use in general medical practice and to convince clinicians and patients that early intervention for drinking that hasn’t yet wreaked havoc is both possible and useful.

"We’re trying to increase the accessibility and attractiveness of treatment to a much broader spectrum of people," said Mark L. Willenbring, a psychiatrist who directs the Division of Treatment and Recovery Research at NIAAA.

Those especially targeted in the guidelines are heavy drinkers who are not yet physically dependent on alcohol but are at risk for becoming so.

"We know that that group responds very, very well to what we call facilitated self-change and brief motivational counseling. We could make that very widely available without much cost," Willenbring said.

A big part of the new strategy is to make primary care physicians — people without specialized training in addiction medicine — think about alcohol abuse the way many now think about depression, anxiety and obsessive-compulsive disorder. Which is to say, they need to think of it as something common, diagnosable and within their capacity to treat. The guidelines make this easy: The screening tool for alcohol problems consists of a single question. For men: How many days in the past year have you had five or more drinks? For women: How many days in the past year have you had four or more drinks?

"Most doctors don’t know how to make the diagnosis and don’t really try to do anything about it until it is so easy to diagnose that all you have to do is glance at the patient," said Charles P. O’Brien, a professor of psychiatry at the University of Pennsylvania who has been treating alcoholics for 38 years.

"It used to be said that you can’t treat somebody until they are down and out. But when they are down and out, they are really hard to treat," O’Brien said.

Willenbring concurs.

"I think there is a belief that people with more moderate levels of dependence don’t know they have a problem. I think they do. But they don’t think rehab is the model of treatment for them — and I don’t, either."

The sort of therapy both advocate does not involve magic bullets or easy answers or effortless behavior change. But it does enlist pills that help a little, quite a bit of talk and lots of self-discipline.

And what does it get a person?

Perhaps not surprisingly, there’s evidence that getting control of a drinking problem early can improve one’s health, completely apart from the social, psychological and familial benefits it brings.

Looking at death rates

A study published two years ago looked at the experience of 628 men and women who entered alcoholism treatment (either in residential rehab or as outpatients) in their mid-30s and were followed for 16 years.

Over that period, 121 died, or 1.2 percent a year. The average age of death was 48. But the chance of dying was significantly lower in people who after the first year were abstinent or had no drinking-related problems or symptoms.

So how successful is treatment, or at least how successful has it been?

Researchers in 2000 analyzed seven studies, one going back to the late 1970s, in which more than 8,000 people were treated for alcoholism in various ways, including with drugs. After a single course of treatment, one-fourth were abstinent for at least a year and one-tenth dramatically decreased their drinking. The rest, about two-thirds of the subjects, drank less often and in quantities averaging less than half of what they consumed before treatment. Mortality in the first year was 1.5 percent.

Some of those patients had a four-week stay in "rehab," but most did not. A long treatment-center admission as the optimal strategy to stop a serious drinking problem is much more the model of the 1980s than the 2000s. The newer one emphasizes outpatient treatment — occasionally after a brief hospital stay for acute detoxification, if necessary — with care provided by non-specialists in many cases.

How often contemporary treatment succeeds was also explored in a complicated clinical trial of about 1,400 alcohol-dependent men and women, average age 44 and consuming 12 drinks a day, that was published in the Journal of the American Medical Association in 2006.

The researchers randomly assigned the patients to nine groups. Four of the groups got nine sessions, conducted by a doctor or nurse and lasting at least 20 minutes, that reviewed the health consequences of excessive drinking, encouraged abstinence and attendance at Alcoholics Anonymous meetings, and urged adherence to the study medicines. Four of the groups also got intensive counseling by alcohol-addiction experts — up to 20 hour-long sessions.

Drug therapy

Some of the patients were assigned to take a drug for three months: either naltrexone, which blocks opiate receptors in the brain that are involved in alcohol’s "reward pathways," or acamprosate, which works through so-called GABA receptors to decrease the anxiety and restlessness that can come with abstinence. Some got placebo pills.

A year later, there were no big differences among any of the groups, although there were some interesting small ones. (This was true even with what the researchers considered the placebo group, the people who received specialized alcohol counseling but no time with a physician and no pills.)

People who met regularly with a doctor or nurse and then got either naltrexone or the intensive counseling did equally well; about 66 percent were abstinent. People who had those sessions and got placebos did less well; 59 percent were abstinent. Those who got intensive counseling but no pills, neither active ones nor placebos, had an intermediate outcome, with 62 percent abstinent.

Unlike some other studies, this one showed no benefit from acamprosate. But that may not be the last word.

Interesting findings

A clinical trial not yet published showed the drug worked only when started during a period of abstinence, not while a person was still drinking. And last month researchers reported more evidence that GABA receptors play a role in alcohol addiction. Laboratory rats that got the drug gabapentin, which enhances the action of GABA, drank less — but only if they were already chronically exposed to alcohol. Those that used alcohol only occasionally did not show such an effect, suggesting the pre-existing state was crucial to the response.

Abstinence, in almost all practitioners’ minds, is always the goal. But its absence doesn’t signal abject failure.

"It is a fiction that the typical change process is a sudden transformation," Willenbring said. "The more common is a change process that lasts years and is characterized by lengthening periods of sobriety and shorter relapses until they are gone."

In that way, alcohol abuse is like depression. In another way, too.

"Recovery from depression requires effort. The same is true for alcohol dependence," he said.

And in both cases, he thinks they’re really worth the effort.

Fox News — A warning from the Colorado Springs Police Department. Detectives with Metro Vice Narcotics said more and more teens are throwing "pharm parties," or get-togethers where young adults abuse prescription drugs.

Detectives said most teens get the medications from their parents and grandparents medicine cabinets. They said from there, the prescription drugs are then taken to parties and shared with the group.

Over the past few months, police said a handful of teenagers have overdosed on the drugs. They said some of the more popular pills include Xanax, Valium, Percoset, Oxycontin, Vikatin and Adderall to name a few.

It is called "trail mix," or a bowl filled with prescription drugs free for the taking. Detectives with the Colorado Springs Police Department said "trail mix" is the new party favor at many teen get-togethers.

"Then the kids just take turns taking a pill of their choice to see if it affects them and to see if they like it or not," an undercover officer with Metro VNI said.

Detectives with VNI said they have seen youth ages 12 to 22 abuse the drugs.

"I have had reports of pills being taken from grandma and grandpas when they go visit, aunts and uncles, friends going over to another kids house and taking from that medicine cabinet," a VNI Detective said.

The most popular pills detectives said are schedule II medications, or drugs that are highly addictive.

"Cocaine and meth are schedule II, Adderall, Oxycontin and Percosit are all schedule II as well, so they have the same abuse and addiction potential," a VNI Detective said.

Police said the internet has only made things worse by spreading information.

"They did an interview with a youth who overdosed, and the way he chose what medication to take was if it said ‘do not use with alcohol,’ that meant to him it was a great drug to use," a VNI Detective said.

They said many teens think prescription drugs are safe because they are prescribed by a doctor.

"Definitely, we have seen overdoses," a VNI Detective said.

To keep your kids safe, police said treat your pills like a gun, lock them up and put them away.

Detectives with VNI said prescription drug abuse is a nationwide problem that also affects millions of adults. If you or someone you know is abusing prescription pills log onto the website below for help.

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.
