It seems that the most vocal advocating legalization are those under the age of majority who seem to think that it will be legalized in 2018.  What they do not grasp is that it will remain illegal for them.  They laugh this off as they feel it is unenforceable, and they would be correct.  What would the penalties be for those under 19 caught in possession of marijuana.  A fine for a population unable to pay fines?  Incarceration for a victimless crime which would be hypocritical and cause widespread dissent?  And there is Dr. Leitch's concern that marijuana can affect functioning of a growing brain- the biggest issue of all.

There is also the issue of who can grow marijuana, how much they can grow, and whether they can give or sell to friends- an activity the young would engage in.

O'Leary needs to give this issue more thought or he will add to the chaos Trudeau has created with his thoughtlessness of the full implications of this issue.  Popularity seeking can bear a heavy cost.
