Your assumptions are silly. If people are dying from pot smoking, they are doing so now.

Current law does nothing to limit access to minors.  Every high school has at least several pot dealers.

You must be assuming that a whole crop of new pot smokers will magically appear from the wilderness, smoking enough dope to kill them.  No one ever died from smoking a bit of pot.  Your comment is not very well informed.

As for the revenue, better it goes into provincial coffers (which might help fund desperately needed infrastructure programs, or other public goods) than flowing into the hands of criminals.  Eh?
