It makes my blood boil to see such an important issue as cannabis and mental health debased by such ill-informed articles. There is no evidence whatsoever that today's cannabis is "20 times as powerful as the natural product", and simply repeating this myth will not make it true. As the European Monitoring Centre for Drugs reported in 2004, there has always been strong cannabis and some imported samples are at least as strong as "home-grown". We have a total lack of some very basic information about cannabis, the sort of things that we really should know. We don't know how strong any sample will be, or how pure it is. This is entirely due to the policy of prohibition which prevents any effective regulation of the supply side. It's as if people were buying booze in unlabelled plastic bags containing anything from beer to vodka to moonshine, such is the way prohibition works. Cannabis is called a "controlled drug", but in reality it is nothing of the sort. But cannabis isn't simply THC and strength is not the only consideration. Different types of cannabis contain very different ratios of active chemicals, so it's important for any meaningful study to know what people are using. Due to prohibition, this basic information is not available. The area of London which claims to have seen a doubling of schizophrenia over 30-40 years is Brixton, where cannabis use is virtually the norm; 30 years ago it certainly wasn't; but 30 years ago the population was utterly different and lifestyles were different.
