Not on its own. But you could if it's laced with another drug. Legalizing it would avoid that since you'd be purchasing it from a shop that has a license to sell it.
Because the Republican mindset is being scared of literally everything. All their decisions are based on fear - of the "other", brown people, gay people, any change at all. They project their fears into everyone. They'll lie and manipulate their own world view to fit the things they're frightened of (basically everything).Why do republican candidates never have to shit to offer? All they want to do is restrict and take shit away from people. And they usually do it by spreading bullshit like in this case. Make me sick.
Not overdose like you're thinking. You can "OD" on weed, but it just gets you to the point of more likely to have a panic attack. That's about it.
