It's always about regulation, and how it is apportioned. Complete de-criminalizing will allow you to grow, but not sell.
Getting licensed to grow/sell will be costly, but worth it.
If you go through 3 oz's a month, your not "medical" your "chronic" and just abuse it. Go ahead, say something stupid. It'll just prove the point.
I'll get more stoned on one hit than you choking 3-4 bongloads. Enjoy!
