Yea, I always wondered about that. The people who were pushing legalization for hemp products, really wanted to smoke it to relax. The politicians knew this and said "hey they just want to legalize it to smoke it, not to make hemp products, the liars!", so it never passed.
Now its in your face politics, which gives the politicians much fewer ways to wriggle out. "Hey, we want to legalize pot to use as a legal drug like alcohol, but without many of the negative and potentially fatal side effects of alcohol. We want to come home from work and smoke a j to relax".
This seems to be a much more effective, (and truthful) way to present the case for legalization. Whereas before they looked like a bunch of stoners trying to pull the wool over the governments eyes, now they look like responsible adults making responsible choices. We would rather smoke weed than drink booze thank you.
