First of all it should ABSOLUTELY NOT be a Constitutional ammendment. It can be handled statuatorily. Second, funding schools by selling drugs seems a bit nefarious. Third, are people prepared to legalize meth and/or heroin because pot MIGHT be a gateway drug? It may not be but if it turns out that it is, then the push to legalize harder drugs and "tax" them will happen. Also, if all this bullshit is legalized because Americans are obsessed with intoxicants (this includes energy drinks), then NO tax funding for addiction treatment. Just my .02.
