Why - is it your theory that many people responsible enough to avoid pot when it's illegal will suddenly become irresponsible enough to not only use pot but render themselves unemployable when it's legal? Sounds unlikely ... is that YOUR plan?
Actually pot users do “render themselves unemployable” as many businesses drug test and will fire one for being a pot user.
Too bad all the energy used to legalize pot isn’t being used by these same advocates to get the govt out of a taxpayers fiscal house which is most important, imo.
