Driving under the influence is illegal.
Give these people stiff sentences no different than booze or driving after taking some medication.
Beyond that, screaming that “OMG this needs to be kept illegal because DUIs”, while you keep booze legal is still keeping you in a position where you are trying to keep two different positions for two things that are used almost the same way.
I've personally seen it destroy many lives especially the lives of young people as it serves as a gateway drug leading to harder stuff.
Many times I just wonder just why do I bother warning people about the dangers of these stuff as all I get is a cussing out from them, them hating me, and the equivalent of a "F### Off and leave me alone, as I'll live my life as I see fit"
