I have to agree that there is definently legitimate medical use. I know of some pretty amazing things happening after vaping a little dmt. Once I vaped a small amount with an older guy who had a brain tumor. He said all the pressure in his head went away and it was the best he had felt in a very long time.

Another time I gave some to one of my friends to smoke out (or would vape out be the correct term) a friend of his who was in a car accident and now is paralyzed. After taking a hit he temporarily regained control of his arms. For about thirty minutes he was able to move his arms around again, something doctors told him he would never be able to do.

Makes me curious if vaping dmt or drinking ayahuasca before physical therapy might make it more efficient. Although, I could see how purging while paralyzed might be pretty terrible.
