I am sure you have had some exposure to the negative impacts of cannabis products through either personal or professional life. And likely those have sent you down this road where prohibition seems like a good option. I understand and respect the position, but I put a lot of personal energy into opposing it.
Most of my experience has been professional through the health care system. And in my opinion after many years of exposure to emergency medicine, child acute and chronic psychiatry, and death through the coroners system. I have come to the conclusion that the vast majority of trouble from cannabis comes from the consequence of prohibition. Unjust application of criminal law, unnecessary involvement in the criminal world, exposure to unsafe product, and very importantly the bizzare response from schools and parents to the majority of kids who are occasional users with very little risk of progression then getting labeled with draconian sanctions applied.
