Where is the profits? There is more money in having someone sign up for a lifetime regiment of pills than smoking a little pot. Making Hemp illegal opened up 5 new industries including paper and wood. You can literally make steel strength materials with Hemp. The same idea applies to medical cannabis, there is more money if you provide crapper solutions at higher price points; such as Oxycodone. This plays into insurance companies after a while as well and I could go on and on about how there are very powerful people in this country would have ALOT to lose on the legalization movement, it won't come easily.
