"why not get involved in legalized cannabis"
Because it makes you a sellout, because you are hurting your fellow cannabis user, because it puts nonviolent growers in prison, because your tax dollars go to busting patients trying to stay functional with cannabis outside the legal regime. because legal weed is shitty, because it's toxic, because it allows pesticides and fungicides that havent been tested, just like the legalized tobacco industry. Because legal weed doesn't allow branding or logos or anything to do with the real cannabis culture, just block lettering and government warnings about how dangerous cannabis is. because legal weed comes in 10 times the necessary plastic packaging. because there's a snitch line to turn in anyone growing or selling outside the legal regime. because legal (licensed) insiders lobby government and police to crack down on the black market, ie, on freedom. because a plant should never be legalized, just decriminalized. because legalization stands for control and profit, not liberty.
but hey yeah if there is a buck to be made why not right??
