So I'm assuming weed laws have put an end to the "peer pressure" of teens getting other teens to smoke it?

Life always comes down to personal choices and it's always the hard ones that are the most important. No law will ever change that.

Not saying that laws are the reason, but there isn't much childhood peer pressure to smoke weed. There is peer pressure around iMessage in some countries just cause of Apple, rather than kids finding the obvious workarounds.
