Same with second hand cigarette smoke causing cancer. There were lots of conflicting studies with no overall proof - the government still brought in the smoking ban.
The problem is the same with cannabis, the supporters say it's fine, the detractors say it's harmful, both come up with studies and research to prove their points.
There is a link between cannabis smokers and mental health disorders, but it might be a chicken and egg thing - those most likely to suffer mental illness gravitate towards smoking dope which in turn exacerbates their mental health problems more rapidly.
It's still a semi-addictive psychoactive drug that impairs the senses and judgement, much like the legal highs that have been banned recently, so don't expect government to approve it anytime soon.
