DMT is classified in the United States as a Schedule I drug under the Controlled Substances Act of 1970. got that from wiki just to make sure and called my friend who own a head shop and said yes some places or selling an item called DMT but no drugs in it jus the name.....I cant speak for your headshop I can only tell you what my friend said.......and I did already know it was a drug but wasnt sure about how the PO PO felt about it thats why I used the wiki to find out. So take the info for what its worth I may be way off base just telling you what my head shop friend said and what wiki says.
could be 5MeO-DMT, not quite the same thing though.
But wouldn't 5-meo-dmt be an anologue thus still making it illegal?
