“Abstinence is the best way to avoid drug addiction. But in many societies, drug use is the norm, not the exception, especially by youth. What keeps the majority of users from becoming addicted? How drugs are taken has something to do with it, according to pharmacology researchers at the University of Montreal. “Why do some drug users become addicts? The amount of drugs they take over time is one factor, but the speed with which the substance enters and exits the brain can be just as important,” explained Professor Anne-Noël Samaha, who supervised the study into how pharmacokinetic factors govern addiction.
“Pharmacokinetics is about what happens to a drug once it is inside the body and brain,” she said. “For example, when you smoke a joint, the level of cannabis in the brain increases and decreases much more quickly than when you eat a magic brownie. And this variation depends on how you are taking the drug”. What emerges from this research is that in addition to the social context and the predispositions of the individual, the risk of becoming addicted is influenced both by how fast a drug gets to the brain and by whether the amount of drug in the brain fluctuates or remains constant during intoxication. In other words, people using drugs must be aware that specific ways of using and routes of administration influence their risk of addiction.”
