Hi I'm a Coloradoan. We just got home on Saturday. Spent 12 days and smoked everyday just like at home. Talked to a lot of folks about Ganga and got the same response from everyone.
1 Ganga is legal for medical ( cards available Nov 2015, and religious reasons.
2 as long as you carry under 2 oz and don't toke and drive you will not get a ticket. The police do not currently ticket you because the government has not given them the paper tickets to do so AND if they do somehow give you the US $4.50 ticket you then have the right to contest and they then must have it lab tested for US $20.00 to prove that it is Ganga. The police can't afford that. So be smart and don't carry more than 4 sticks of green and all is well.
Americanized places have signs prohibiting Ganga but it's rarely inforced. Ask them before you spark up.
Local places- the response will be "why- I can get you some? Or laughter over such a silly question
Just got back and homesick already- Sigh.......
