Colorado has taken a California-like approach to its medical weed program, licensing hundreds of dispensaries around the state, and so far, so good. Patients are getting their medicine and generating lots of karma-free dollars in the process. The state collected $2.2 million in sales taxes for 2010 and Denver took in the same amount in local sales tax. But those numbers might be incomplete, as they don’t include what must be a marked increase in the sales of lighters, bongs, and presumably, soft drinks.
