There are just as many cons to legalizing marijuana as there are pros. I'm all for medicinal marijuana but we all know that will be abused by people like those on here supporting it. How can you disprove chronic nausea? And if you think legalization or even decriminalization will reduce crime you watch too much tv. There will always be a clandestine grow operation and an underground need. Look at prescription drugs. I heard of a guy selling Foclin to college students. Novel effort but futile I'm afraid.
