New Report on Canada’s War on Drugs

April 2nd, 2010

Report from UBC’s Urban Health Research Initiative finds that Canada’s so-called war on drugs has not stopped the supply of drugs in the streets.

According to the new report released in Ottawa last week, our war on drugs has only served to increase drug-related violence.

Authors reviewed international research and concluded that 87% of studies linked strict law enforcement with an increased “drug-market violence”.

Dr. Evan Wood, the reports co-author, said that the “gun violence that we’ve seen in B.C., as in Mexico and the U.S., appears to be directly attributable to drug prohibition.”

He explains that prohibition simply drives up the value of drugs, thus creating an extremely lucrative market.

The report, thus, concludes that drug issues should be addressed as public health issues, and not as law and order, advocating that money should be spent on health measures that have better results than costly law-enforcement that don’t actually address drug addiction.

According to the report, we should be addressed the demand, not the supply.

This is a perspective echoed by the Obama administration and his new drug czar Gil Kerlikowske.

New OxyContin Policies for Manitoba

March 29th, 2010

According to an official news release from the Health Living, Youth and Seniors Minister Jim Rondeau additional safeguards for the use of OxyContin will soon be placed in Manitoba.

The province is planning “aggressive action on OxyContin misuse”.

This includes moving the prescription drug to part three of the Provincial Drug Program Formulary, which includes an education campaign and funding for training to facilitate an increase in the number of physicians with a methadone license.

The Provincial Drug Program Formulary consists of three parts, each with an increasing number of controls. Moving OxyContin to the third part means the highest level of controls on the prescribing of the drug in addition to the existing controls.

Existing controls include the Manitoba Prescribing Practices Program, which is used to monitor and control the prescription and dispensation of certain restricted drugs.

The education campaign, aimed at patients with OxyContin prescriptions as well as the general public, is currently being developed. Manitoba is looking to increase understanding of the dangers of misuse of the painkiller and will include posters and pamphlets to be distributed to medical clinics and pharmacies around the province.

Furthermore, as part of the Minister’s overall strategy is the increased capacity to provide methadone treatment for OxyContin addiction. This is to include funding for training of physicians in methadone treatment to facilitate the overall increase in the number of physicians who are licensed and trained to administer methadone as part of drug addiction treatment.

US Children are Huffing

March 22nd, 2010

According to a new study from the US Department of Health and Human Services, inhalants have become the drug of choice.

According to the study, using data collected from 2006-08 surveys on drug use and health, more 12-year olds admit to using inhalants to get high than prescription medications, marijuana, cocaine and hallucinogens. Alcohol, on other hand, is the only other substance used more among the age group.

Huffing is the act of inhaling vapours to get high. Children huff such common household products as gasoline, nail polish, bleach, paint solvents, and cleaning sprays making it a difficult problem to combat.

Huffing can cause cardiac arrest, lead to brain, heart, liver kidney damage, and addiction.

The recent survey revealed that about 7 percent of 12-year olds used inhalants to get high, compared to 5 percent who used prescription medications, 1.4 percent who used marijuana, and less than 1 percent who used cocaine and hallucinogens.

The percentage of youth using inhalants has remained steady over recent years.

There is also a perception, experts say, that they are not dangerous to use. According to the National Institute on Drug Abuse, from 2001 to 2009 the number of 8th graders who believed inhalants were risky dropped from 75 percent to 58 percent.

A dangerous trend, they say, as where there is a lower perception of risk, there is increased use.

Consequently, inhalants will be the target of a new public education campaign, aimed at youth and their parents.

Rehabilitation for Cocaine Addiction Works, According to New Study

March 15th, 2010

According to a new study from the UK’s National Treatment Agency for Substance Abuse (NTA), cocaine addiction recovery is very possible with addiction treatment that includes individual psychotherapy.


According to a recent study, an astounding one in ten entering drug addiction treatment in England are entering for cocaine addiction, a four-percent increase in the last four years.

Of these, more than one-third are 18-24 year olds from a broad spectrum of social backgrounds. They are also more likely to have jobs and are less likely to have housing problems.

According to Paul Hayes, NTA chief executive, although there has been an increase in the number of people using cocaine, they are also seeing more people seeking addiction treatment. Very good news indeed.

About 70% of the cocaine addicts in treatment stay in treatment, and either stop using cocaine completely or substantially reduce their use within six months of entering treatment—that is, 61% stop cocaine altogether and 11% substantially reduce their use.

Furthermore, those who are newly entering drug rehab for cocaine addiction also reduce their use of other drugs, including cannabis, alcohol, and amphetamines.

The study, which monitored over 3,000 study participants, represents the largest ever study into the effectiveness of cocaine addiction treatment in England.

Anxiety Drug Addiction Explained by New Research

February 24th, 2010

New research explains how addiction to prescription anxiety medication works, and may lead to development non-addictive versions of the drugs.

Scientists from the US and Switzerland have discovered how anxiety medications, such benzodiazepine drugs as Ativan, Xanax, and Valium, work in the brain. As it turns out, the drugs use the same reward pathways as heroin and cannabis—pathways that may lead to addiction.

The calming effects of benzos are due to an increased activity of the neurotransmitter GABA (gamma-aminobutyric acid). This in turn activates dopamine, the ‘gratification hormone’, resulting in a reward pathway in the brain.

Reward pathways are both naturally occurring and already exist in the brain. They are an evolutionary mechanism that was essential to our survival. Their main function is to make us feel pleasure when we engage in behaviours central to survival—such as eating or sex.

Opioids, such as heroin, and cannabis work in the same fashion. And dopamine, as we know from new research earlier this month, is directly linked to a propensity for addiction.

Researchers behind the study, published in the journal Nature, say these findings may lead to non-addictive alternative benzodiazepines. Benzos work by binding to a specific part of the GABA, the alpha 1 sub-unit of GABA type A receptor according to scientists. Developing similar drugs that bind to a different part of the GABA may offer the same benefits and calming-effects without the addictive side effects.

Drug companies for quite some time have been trying to develop a new generation of benzos with very little success. This, however, could be the breakthrough needed.

Hormone Dopamine Linked to Addiction and Risk-Taking

February 15th, 2010

New research on dopamine and dopamine receptor profiles could lead to new drug addiction prevention and treatments.

Japanese and Danish scientists have shown in new research that those with higher dopamine levels in the brain have a greater need for stimulation, due in part to the lowered dopamine-sensitivity.

Dopamine is the “gratification” hormone, widely known to relate to the physiology of addiction. Previous research has discovered that drug addictions such as cocaine addiction work by causing a build-up of dopamine in the brain. This build up, in turn, causes a lower sensitivity to the neurotransmitter.

However, according to the new research, it is the naturally occurring higher levels of dopamine in the brain that can lead to addictive behaviours. Dopamine levels can indicate a natural predisposition to risk-taking, and addiction.

Dopamine has been connected to both behaviours—each involve chasing a high, whether naturally induced or chemically. As well, drug addiction can be classified as a high-risk behaviour. Studies have shown that sensation seeking, the constant need for stimulation, and drug or alcohol abuse involves the same reward system in the brain.

Higher levels of dopamine, and lower sensitivity to the hormone, leads to greater risk-taking—and thus greater chance of addiction to drugs, gambling, and more.

Lead by Albert Gjedde of Copenhagen University, researchers used brain scans of volunteers to measure dopamine and dopamine receptor levels. Those on the higher end of the dopamine scale felt less affects from the same amount of the hormone than those on the lower end of the scale.

They also discovered that those who fell on opposite ends of the scale had significantly different dopamine and dopamine receptor profiles.

Their research suggests that it could be more effective to increase or decrease dopamine levels, rather than try to block dopamine receptors in the brain, to treat drug addiction. These findings could help to develop new ways to prevent and treat addiction.

How Cocaine Addiction Works

January 22nd, 2010

What is Cocaine
Cocaine is a stimulant, a psychoactive drug that temporarily increases mental and/or physical functioning. Unlike other stimulants, cocaine is not used as a prescription medicine, but is an illicit drug carefully controlled throughout the world. Cocaine is used primarily recreationally and is a widely abused drug.

Cocaine is highly addictive.

Cocaine was very popular throughout most of the 1980s and 90s, and recent studies suggest that its popularity continues strong. Cocaine, also known as “coke”, “c”, “snow”, “flake” and “blow” among other nicknames, is commonly sold on the streets as a fine white powder.

“Crack”, on the other hand, is freebase cocaine—a water-insoluble cocaine base. Crack is processed to be smokeable. It is the crackling noises of smoking the drug that has given it its name.

In 2007, there were approximately 2.1 million cocaine users in the US alone, 610,000 of who were current crack users. Eighteen to 25 year olds represent the highest number of current users. 

Cocaine Addiction & Other Dangers
Repeated cocaine use can result in addiction. New research into cocaine addiction in the brain is uncovering why. According to the National Institute on Drug Abuse (NIDA), in 2007 close to 1.6 million Americans could be classified as addicted to or abusing cocaine, according to the general diagnostic guidelines.

Cocaine is a very dangerous drug, especially when over- or misused. A 2005 study reported that almost 450,000 of the 1,450,000 visits to emergency rooms across the US were due to cocaine use/misuse. This boils down to almost 1 in 3 ER visits involving cocaine.

There is no safe form of cocaine. Nor is there a safe way to use cocaine. Whether by snorting, injecting or smoking cocaine, you are still at risk of imbibing toxic amounts of the drug. Too much cocaine can result in acute cardiovascular or cerebrovascular emergencies, seizures, and sudden death.

How Cocaine Works in the Brain
Cocaine causes pleasurable effects by stimulating the pleasure and reward centers of the brain. Cocaine stimulates the central nervous system, causing increased levels of dopamine in the reward center. Dopamine is the neurotransmitter associated with pleasure and movement. Normally, certain brain cells, called neurons, use dopamine to communicate amongst each other. In this process, dopamine is released in the brain in response to a pleasure signal. The dopamine-releasing cell recycles the neurotransmitter, shutting off the communication between the neurons.

However, cocaine prevents the dopamine recycling process, resulting in a build up of dopamine in the brain. This causes a never-ending chatter between the neurons—the euphoric high.

Repeated long-term cocaine use causes changes to the brain’s functioning leading to addiction.  

How Cocaine Addiction Works
The risks for cocaine addiction are high. New research suggests that prolonged use of cocaine changes a genetic expression, or the behaviour of the gene, in the brain resulting in the prevention of specific enzymes from shutting genes off in the pleasure circuits of the brain. This causes heightened cravings for the drug, and thus drug-seeking behaviours.

As well, with continued use, the brain builds a tolerance for the drug. Continued and prolonged exposure to the drug causes the brain to adapt so that the reward pathways become less sensitive to both natural reinforcements as well as cocaine itself. This decreased sensitivity is a result of decreased amounts of dopamine receptors in the brain, and is also the root of the drug addiction.

Furthermore, the risks of relapse are high with cocaine, as the drug will have a strong hold on the addicted brain even after long periods of sobriety. Research has shown that physical cues, or triggers, cause visceral memories of the using experience that result in intense cravings and even relapse.

 
Cocaine Addiction Treatment
A Cocaine Addiction Treatment Program is vitally important to a successful recovery from addiction. Rarely does going it alone or going cold turkey work. Addiction is a complicated process with deep roots. Addiction recovery requires support, therapy, and a retraining of the brain.

We believe in an all-encompassing approach to cocaine and all drug addiction treatments. Our Cocaine Addiction Treatment Program treats more than the physical addiction, healing the underlying issues at play. We work together with each of our clients to design an addiction treatment program that works for each individual.

With our different therapies, clients learn to take personal responsibility for their decisions, good and bad, to recognize addiction triggers, and to cope with life’s stresses in a healthy and productive fashion.

Cocaine Addiction: Gene Alterations From Prolonged Cocaine Use

January 18th, 2010

US Researchers at NIDA report having identified a key brain mechanism, better explaining how and why cocaine addiction occurs.

Announced last week, January 7th 2009, government scientists at the National Institute on Drug Abuse (NIDA) said that the new discoveries about the root of cocaine addiction could lead to the development of new drug treatments.

In experiments with mice, scientists showed how cocaine affects the epigenetic process histone methylation. Prolonged cocaine use, they found, can cause permanent changes to the way certain genes turn on and off.

Epigenetic is a process that influences a gene’s expression or appearance without changing the underlying DNA sequence, causing the gene to behave, or express, itself differently.

Histone methylation is the modification of certain amino acids in a histone protein, or the protein around which a DNA strand wind, which essentially turns the DNA off.

Cocaine in the brain prevents the enzyme from shutting off genes in the pleasure circuits of the brain, heightening cravings for more cocaine.

Furthermore, scientists were able to reverse the effects by increasing the activity of that particular gene, completely reversing the effects of chronic cocaine use. As well, scientists reported that it is likely that this be the same process for other addictions, including alcohol addiction, thereby potentially leading to new, more effective, addiction treatments.

“This fundamental discovery advances our understanding of how cocaine addiction works,” Dr. Nora D. Volkow, director of NIDA, said via press release. “Although more research will be required, these findings have identified a key new player in the molecular cascade triggered by repeated cocaine exposure, and thus a potential novel target for the development of addiction medications.”

The findings also help to explain addiction’s long-term cravings and relapse despite periods of total abstinence.

New Cocaine Addiction Treatment on the Horizon: A Bacterial Enzyme

January 6th, 2010

Researchers in the UK have identified a bacterial enzyme that, they say, breaks cocaine down in the body, effectively reducing the drug’s addictiveness and may help fight both cocaine addiction and overdose.

The naturally occurring bacterial enzyme, Cocaine esterase or CocE, essentially breaks cocaine molecules down in the body, reducing its physical addictiveness and eventually lead to a new way to treat cocaine addiction, as well as help reduce cocaine overdose.

CocE, researchers found, is only active in the body for a rather short period of time. However, they have also found a more stable version in a double mutant bacterial version, DM CocE.

In their clinical trial, published in the Journal of Pharmacology and Experimental Therapeutics, researchers from The Scripps Research Institute trained rats to self-administer cocaine. By pressing a button, cocaine would be released to the rats, mimicking human drug-seeking behaviour common to all addictions.

Once given the double mutant bacterial enzyme, the rats pressed the cocaine-administering button far less, suggesting that the enzyme successfully broke the cocaine down and rendered it far less physically addictive.

Lead researcher told reporters that although the enzyme is not a fail-safe cure for “determined users”, it could nonetheless prove to be a new effective therapeutic approach.

As with all medical interventions to treat addiction, this new treatment should be used in conjunction with a therapeutic drug addiction treatment program.

However, unlike others, it seems at first to have far less harmful side effects and be less addictive in the long term, and could very well prove to be an exciting development in the treatment of cocaine addiction.
