Corruption in our province has most likely lead to homicide.... but in general i agree that legalized drugs could cut out organized crime groups.
Drug addiction is a health / medical issue.... and needs to be treated as such.
If a minor really wants to get drunk / high...... they could likely buy a bag of weed within a block of their home in less than 5 minutes.... or grab a bottle of booze from a parents liqour cabinet..
Do we really need archiac laws to protect young people..... i think not. If kids want to get booze/weed... they will always find a way. European countries are so far ahead of us in so many ways.
