My girlfriend vapes marijuana too. She had a migraine. Now she feels much better. Not sure if it's vaping weed, but still.
Of course, I vape it too. Just once a week maybe to relax. It's also a good option to relax after a stressful working day.
When I tried it for the first time, didn't know what was wrong. But I didn't like and didn't understand it. Vaping weed? What for? Then I tried it with my friend and the result was different. I thought maybe the reason was in my vaping device as I bought the cheapest one and it was of poor quality. Then I've read some reviews here

Was difficult for me to choose, but I stopped on Mig Vapor DRAY. Quite satisfied with it.
Maybe I'll buy a new one soon, but that's what I have now.
