I think that based on the evidence we have you are right about the relative risks. However I 1) think that if we had a do-over, we should outlaw tobacco but keep nicotine legal and 2), based on anecdotal experience I think we will end up finding in 30-40 years the true health/mental health outcomes of cannabis since it will be more easily studied 3) my big worry is less the legalization and more of the perverse incentives companies will have to promote its use through industry funded health studies, advertisements, etc...
