They do not want to answer that or consider other variables on this subject, they just want to solely focus on endlessly suggesting there is a link to cannabis and schizophrenia because it is the only line politicians are left with to try to justify continued prohibition.

Recently schizophrenia has even been linked to infection in early childhood, it is also a brain degenerative disease with genetic predisposition but apparently those things are not important neither. It is clearly a very complex condition, I also have no doubt cannabis use can be linked to an onset of it but clearly it can not cause it outright, anyone who claims so should have no place trying to put out anything resembling real science.

Regardless all these excuses for continued prohibition have little impact on the massively failed war on drugs and if we want to understand these issues better and treat those who may be at risk of an early onset or some developing psychosis it needs to be legalised, studied properly and the public educated on it properly. Ironically cannabinoids have also been found to have anti-psychotic effects and is speculated as to why people with schizophrenia actually use the drug, while clearly THC is the culprit in making symptoms worse.
