I don't take drugs. I think there are good reasons for people to not take cannabis. I am strongly in favour of cannabis legalisation.

The amount of time and money spent dealing with cannabis is mind-boggling. About 50,000[1] Mexicans have been murdered in the recent drug wars. Some of those are because cannabis is illegal.

Cannabis prohibition is going to be viewed with horror in the future.
