Waste 'o' time. Nobody cares but pot smokers. I hate to sound assumptious, but you don't sound like the type who's willing to go to jail for the cause and those are the only people who can make a difference.

If legalizing in a city isn't enough... a paper?

There's already books, essays and articles about the subject, so just leave it alone. I promise you, nobody cares. It's cynical, but it's practical. Believing a paper will make any bit of difference is just an ego trip. Direct your energy into rolling blunts and learn to live with it because it's going to be at least a decade before any real changes start happening.
