Agree. In moderation and within limit, both can have positive effects. Like you said, the problem is, most or many do not use them sparingly. And as always, most folks pimp their substance as the best and it doesn’t hurt them it’s better etc etc.
My guess is there will be pretty clear protocol within the next few years regarding driving while high. It really is no different than drinking and driving. If you are using marijuana, you should not be driving, period. Same with alcohol.
Im not personally a marijuana user, but the lack of long term research about all these new forms of intake, and the general lack of long term substantiated research about it period would make me a bit uneasy.
