Just a point about MJMy daughter who is 17 smoke pot for the first time last year, she is pretty open with my wife and I and we commend her for this and would rather know than not know...... She did it a couple times with friends, then went to a party and smoked another one with her friends a few weeks later, and they all got very sick. She said they had a green out, and luckily where with friends and nothing bad happened other than throwing up... But... she acknowledged that this other pot they smoked was FAR stronger than anything she had smoked before, and now she wants to be sick if she even smells pot... But just goes to show you regulations on how strong it is (THC) and whatever else goes in there are needed for the industry........
