Legalization for adults is the most effective way to reduce access to marijuana by young people, through harnessing the power of the market: young people report that they can currently get illegal-for-all pot more easily than legal-for-adults beer or cigarettes.
This is right out of scripture from the Religion of Pot. I have been hearing this nonsense going back almost a decade, and only the truly pious members of the church of the green weed believe nonsense such as this.
Who are these "Young People" who so report? Stoners? Not a good cross section of the available demographic if you ask me. Sure, Stoner teens can find weed because they've worked diligently to set up their supply lines.
Other kids? Not so much. Unless they know a stoner or something.
