I am particularly interested in, and worried by, the increased availability of skunk - now smoked by very many teenagers.
I have a teenager who smokes skunk, and so do most of his friends. I observe that it makes them paranoid, unhappy, edgy, dis-inhibited, and sometimes aggressive or violent (particularly during the 'come down'). On the other hand, I grew up in a student culture where almost everyone I knew smoked cannabis, and the effects 'back then' were very different - almost universally pleasant. I find skunk's 'nastiness' very worrying indeed.
Traditionally, we have viewed skunk as simply 'strong cannabis'. But researchers have been studying the effects of skunk vs. 'standard' cannabis, and are beginning to identify important differences. Skunk is strengthened by changing its chemical structure to increase its THC content, by removing its cannabidiol (CBD). This leads to observable and worrying effects: specifically, skunk has a clear psychotic effect, while other forms of cannabis which contain CBD as well as THC, it seems, do not. CBD appears to have some positive medical effects too.
You can see one vivid example of the different effects in this , filmed when a BBC investigative journalist took part in an experiment run by Prof. Robin Murray and a research team at the Institute of Psychiatry. There is more info in this New Scientist article and here.
Unfortunately, I think there is a lack of awareness about the differences between skunk and other forms of cannabis, and this leads to misunderstanding and poor policy and treatment. Young people are given poor information, based on out-of-date 'knowledge' about older forms of cannabis. Drugs workers and other adults who remember their own pleasant experiences of cannabis don't understand that skunk is different. The messages about skunk need to be much harder-line, in my opinion. Personally, I would favour separate classification for skunk, higher than other forms of cannabis that contain CBD. Its effects need to be taken much more seriously, and treatment programmes may need to be introduced.
My question for Jacqui is: do you agree (or will you review the research evidence to see if you agree) that skunk is different to, and more dangerous than, other forms of cannabis which contain CBD? And if so, will you do what you can to make sure that 'official' information and policy about skunk are updated?
