The line between medical and recreational is (or at least was) very fuzzy, though.

Before recreational was legal there were a lot of more or less healthy people getting licenses for silly symptoms, like nausea or difficulty sleeping. There was a very low burden or proof and it was pretty well known that a lot of people were making up problems just to get the license.

I don't know of anybody actually doing it, but it's entirely possible that a lot of the not-so-serious medicinal users are now just keeping the license for price discounts and better availability. It'll be interesting to see those numbers in a few years as the licenses need to be renewed.

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.

Nope, I don't have different numbers. I retract my point in the face of this evidence.
