Side effects ?  sure, and mental health problems as well.  Are we controlling marijuana use in North America ?
Obvious answer ............... NO !
The Trudeau government has promised much and delivered very little. (Ok tax the rich )
BUT, the most important aspect of the current problem is  "criminalization" . A teenager gets a lifelong criminal charge on his history if arrested carrying Marijuana.  Note, convictions have become rare, but the "charge" stays on causing problems for many.
Urge the Trudeau government to ....... "decriminalize"  Marijuana, now.  This can be done easily and quickly.
........ and  we wonder why junior Trudeau was never charged with possession of Marijuana.
