Chronic users often relapse because of the unpleasant physical and psychological symptoms they experience when they stop taking the drug. Now, researchers report metabolic changes in the brains of rats during methamphetamine self-administration and withdrawal that could help identify biomarkers and treatments for addiction.

A study of California parents found that current marijuana users administered more discipline techniques of all kinds to their children on average than did non-users. That includes everything from timeouts to, in some cases, physical abuse.

Findings show that the drug induces different signaling changes in the brains of male rats versus their female counterparts, which may suggest there are sex-related mechanisms behind methamphetamine addiction. Delving further into these brain changes could offer insight into sex-specific treatment strategies that could offer better outcomes for people struggling with addiction.

As more people use opioids, many switch to heroin because it's more potent and cheaper -- a trend that complicates disease prevention as health officials crack down on opioids.

A new study now suggests that hijacking another natural system in the brain may help overcome drug addiction. The study shows that administration of oxytocin -- a naturally occurring molecule well known for its role in social bonding and childbirth -- reduces drug-seeking behavior in methamphetamine-addicted rats.

The authors of a new study argue that it is important to distinguish between the roles that alcohol may play in the two different types of deaths. Consequently, they compared postmortem toxicology results for alcohol and other drugs, alone and in combination, in suicide and MVC deaths.

In March 2007, Mexico closed a chemical company accused of illicitly importing more than 60 tons of pseudoephedrine, a methamphetamine precursor chemical. A new study has found that those events were associated with large, extended reductions in cocaine and methamphetamine users in the USA.
