I know that possession of small amounts is decriminalized in the city limits of Denver, and a few other ski towns I think. As far as growing I'm not sure though, I wouldn't think so. Colorado Marijuana Penalties - NORML There it says that possession of 2oz or less is just a $100 fine, but cultivation is still a felony.
No problem. Happy growing and I'm envious. Really starting to consider moving to Colorado when my kids are grown and gone.
