My wife got a body scrub at a spa in Oregon recently. The more exfoliating of the two scrub options (I think salt versus volcanic ash) was based on CBD oil. The spa insisted that it was relaxing and folks got it all the time with no trouble. My wife was sick for the better part of three days, puking and nauseous. Apparently CBD poisoning is a thing, and the amount added to these things (especially in consideration of absorption vectors) is pretty much unregulated.
