I'm not sure why you think millions will now be terrorizing you just because it's being decriminalized? Directing your fear toward drunk drivers and zombie housewifes on legal narcotics is probably a better bet.
Well, we can all cower in fear and worry about what ifs and maybe. Or we can be rational and see the ridiculous society we've created where booze and prescription drugs are magically ok but we choose to demonize less harmful things.
