Weed pretty much has its own shut-off switch. If you do too much, you're pretty much going to sleep after deciding that the chips left in the bag really weren't stale at all, just kinda "flexible".
Banning edibles, lol. Would be like trying to ban jello shooters.
Agreed, it's great to see all the "pro weed" talk, to the point where even a local radio station in my area has some kind of announcement they do at 4:20 PM. At the same time, I believe a lot of this sudden "acceptance" is purely driven by the realization of the revenue potential that legalization would lay the groundwork for. Despite the primary motive, it's still a good thing IMHO.
