Thanks in part to the Netherlands' policy of marijuana decriminalization, there are people living in the Dutch city of Utrecht whose addiction to cannabis prevents them from getting effective treatment for mental illness. According to a September 10 statement from Utrecht Mayor Wolfsen, "There is a group of about eighty people with a chronic psychotic disorder who barely respond to their treatment. A possible explanation for this is their severe dependence [on] cannabis."
A Colorado marijuana innovation is changing the way lawmakers in even the most conservative parts of the country talk about cannabis and is poised to create a rapid expansion in the number of states that have legalized marijuana in some way. But many marijuana advocates view the new political campaign with skepticism, fearing it could halt their movement's momentum. Taken to its logical conclusion, medical marijuana could be a "box canyon" for broader legalization efforts.
The vaping trend seemingly knows no bounds as the first “cannabis” e-cigarette goes on sale in the UK. The KanaVape, which contains hemp, has been legalised for use in France by people with cancer, multiple sclerosis (MS) and other conditions requiring pain relief. It will go on sale around the world tomorrow but the Home Office has cast doubt on whether that would be legal, saying the product must be tested for controlled substances. KanaVape cannot be compared to a joint because it does not contain THC, the chemical causing cannabis highs.
Half a century ago, Hebrew University Prof. Raphael Mechoulam isolated and synthesized THC, the main psychoactive compound in the cannabis plant. By 1963, Mechoulam and his research partners had revealed the structure of cannabidiol (CBD), a key ingredient in cannabis. By the following year they had isolated THC for the first time, established its structure and synthesized it.
The largest study of its kind has unexpectedly concluded that smoking marijuana, even regularly and heavily, does not lead to lung cancer. The new findings "were against our expectations," said Donald Tashkin of the University of California at Los Angeles, a pulmonologist who has studied marijuana for 30 years. Marijuana also contains the chemical THC, which he said may kill aging cells and keep them from becoming cancerous.
A UCSF study suggests patients with chronic pain may experience greater relief if their doctors add cannabinoids - the main ingredient in cannabis or medical marijuana - to an opiates-only treatment. The findings, from a small-scale study, also suggest that a combined therapy could result in reduced opiate dosages. Cannabidiol, or CBD, appears to be very effective against pain and inflammation without creating the "high" created by THC.
"When pure and administered carefully, [cannabis] is one of the most valuable medicines we possess,” wrote British physician John Russell Reynolds in 1890, praising the substance’s curative properties.

The medical use of marijuana is surrounded by a cloud of social, political, and religious controversy, which obscures the facts that should be considered in the debate. This book summarizes what we know about marijuana from evidence-based medicine--the harm it may do and the relief it may bring to patients. The book helps the reader understand not only what science has to say about medical marijuana but also the logic behind the scientific conclusions.
