Marijuana has been illegal because there is no or has been no tax revenue from it. The government could not care less about your health. That includes our current POTUS
. If they cared so deeply about the harmful affects of such things, cigarettes would have disappeared from store shelves years ago. Oh ya, there is big money and big votes to be had from the tobacco industry. Hmmm...can't upset them!
As far as not wanting a marijuana dispensary in your neighborhood, I have news for you. They are already there. The ones you don't see should concern you a lot more than a government authorized brick and mortar dispensary. If medical pot helps people who have illnesses that I wouldn't wish on my worst enemy, I say let them be and go about your day.
