Marijuana is starting to feel like the new normal. In less than 25 years, it’s gone from illicit drug to accepted medical treatment in more than half the country — plus cannabis is now legal recreationally in 10 states.

It’s been a stunning transformation — one that’s thrust weed (and us) into a brand new reality. On this episode, we tackle some of the questions that have popped up along the way. How “medical” are those medical dispensaries, really? What are the risks for pregnant women and their babies? And what’s weed’s power and potential for abuse?
