Weeding it out

Firstly, we need to dispel the belief that the legalisation of Cannabis means that it is a harmless substance. The legality of substances says little about harms: tobacco and alcohol are legal but they still cause significant harm to users and society.

The harm of Cannabis is even greater amongst individuals with a mental illness or a predisposition for having a mental illness. There is evidence showing that Cannabis use precipitates and perpetuates schizophrenia and psychotic disorders. Thus, just like some people are lactose-intolerant some people can be said to be ‘Cannabis -intolerant’.
