Medical marijuana is not subject to any special taxes (aside from normal sales tax on all goods, which is 2.9% across the state + any local sales tax). That amounts to less than $10MM, and it dosn't count towards the tax revenues from Amendment 64, which was the constitutional amendment that legalized recreational marijuana. It's also worth mentioning that because it is relatively easy to access a medical marijuana card in Colorado, heavy recreational users have an incentive to get a medical card.
