If you’re one of the people who wouldn’t have minded destroying my brain in high school -
no thank you.
It would have been YOU destroying your brain. And banning marijuana for adults has been counterproductive in keeping it from kids - for many years (since well before any state had legalized) kids have been reporting that they can get marijuana almost as easily as cigarettes or beer, despite the latter's much greater prevalence in the adult population. Could have something to do with the fact that by banning a commodity you put it in the black market, beyond the reach of effective regulation such as age limits.
If it were controlled like alcohol, you wouldn’t have had anywhere near the level of access to it that you did, and the same goes for kids today.
If you don’t want kids to have access to it, the best way is to legalize and age-regulate it.
