Honestly, if you ever believed the nonsense that marijuana was "medicine," you probably don't have the brain capacity to process the information I'm about to give you. Then again, there's dumb and there's willfully delusional. You can have the ability to know better, but choose to embrace nonsense anyway because you want so desperately to get high.
I'd say that still makes you an idiot. Just that you're an idiot by choice.
At any rate, you know that "medical" marijuana was sold as something desperately needed by the old and the sick suffering from cataracts and glaucoma. In reality, most of the cards approved by doctors go to 25-year-old dumbasses who claim to be suffering from "chronic pain" and "headaches." The doctors know it's a scam too, but they don't care. They figure the public is sufficiently sold on this scam, and many of them probably like to get high too.
