I'm glad this is a topic that has already been discussed (and even commented on by Melissa herself!)
I honestly think if it's used for medicinal use (to avoid taking pharmaceutical drugs) and recommended by a doctor (in a legal state), I don't see why it should be an issue. Obviously cooking it into something like ghee or coconut oil is way better than smoking. Just got to make sure if it makes you munchie, to be sure to know whether you can handle those cravings during a Whole30.
My boyfriend has asked me this question and I'm glad I found the topic and can answer intelligently
