Maggie Koerth-Baker highlights a rarely discussed benefit of marijuana legalization:
Cases of marijuana allergy are rare in the medical literature, but a recent study suggests that they're a lot more common in real life. Reactions range from the annoying (runny noses) to dangerous (anaphylactic shock), but if patients and doctors can't speak freely to one another then patients miss out on treatment and medicine loses valuable information.
I see marijuana legalization as a core matter of human freedom, but it's definitely a plus to be able to have scientists, doctors, and patients honestly and without fear figure out how best to use the plant for various medical needs. When something is hidden and suppressed, it's impossible to know its true costs and benefits. And there are obviously some costs for some. Right now, we can't address them. Some day soon, we will.
