Mark Twain said, "Giving up smoking is the easiest thing in the world. I know because I've done it thousands of times." Many smokers would agree that it's difficult to stay away from cigarettes. A new study in Biological Psychiatry this month now suggests that low dopamine levels that occur as a result of withdrawal from smoking actually promote the relapse to smoking. Dopamine is a brain chemical messenger that is critically important in reward and motivation. Some research suggests that...

Scientists at the Centre for Addiction and Mental Health (CAMH) have identified a potential target for the development of anti-craving medications for people with addictions to stimulants such as methamphetamine. The discovery centers on a brain receptor related to the chemical dopamine, which has a complex role in addictive behaviors. Using brain scans and a novel chemical probe developed in CAMH's Research Imaging Centre, CAMH scientists found that the probe had high levels of binding...

Since mephedrone was made illegal in the UK in 2010, the street price of the drug has risen while the quality has degraded, which in turn may have reduced use of the drug. New research published online today reveals that young people who continued to use mephedrone after it became illegal would switch to a new legal high if it were pure and rated highly by their friends or on the Internet. They would be less deterred by a lack of scientific research on the new drug. Mephedrone is a...
