The Guardian/Mixmag survey is one attempt to explain the facts behind this controversial issue - which sees users claim that more of them use cannabis than energy drinks.

The survey of 15,500 people studied a wide range of illict and legal substances, from alcohol and cannabis to cocaine and MDMA - as well as newer drugs such as mephedrone and synthetic cannabis. These are the results. The answers came from countries around the world, mostly the UK and US.

Australian drug use will be rated in a global survey. Photo: Viki Yemettas Drug and alcohol treatments are on the rise in Australia, new research shows, but little real-time information is available about how, why and what drugs mainstream Australia is using. Fairfax Media is partnering with the Global Drugs Survey, created by Adam Winstock, a Consultant Addiction Psychiatrist and researcher based in London, to help create the largest and most up-to-date snapshot of drug and alcohol use in Australia, and how we compare with the rest of the world. Take part in the survey here Dr Winstock said last year's survey, which 15,000 people filled out globally, including 500 from Australia, showed that, for many, drug use was characterised by confusion and dishonesty. “People are appalling at knowing how their drug use compares to other people,” he said.

Cannabis. New Insight Into How Brain ‘Learns’ Cocaine Addiction - 08/01/2013. A team of researchers says it has solved the longstanding puzzle of why a key protein linked to learning is also needed to become addicted to cocaine.
Results of the study, published in the Aug. 1 issue of the journal Cell, describe how the learning-related protein works with other proteins to forge new pathways in the brain in response to a drug-induced rush of the “pleasure” molecule dopamine. By adding important detail to the process of addiction, the researchers, led by a group at Johns Hopkins, say the work may point the way to new treatments. “The broad question was why and how cocaine strengthened certain circuits in the brain long term, effectively re-wiring the brain for addiction,” says Paul Worley, M.D., a professor in the Solomon H.
Snyder Department of Neuroscience at the Johns Hopkins University School of Medicine. “What we found in this study was how two very different types of systems in the brain work together to make that happen.”
