So yesterday I was smoking a bowl with some people, and after taking my hit I had the distinct taste of spice on my lips. I said something and it turned out he had tried DMT for the first time a week ago and several times throughout the week. I could taste the spice in his lungs or lips on my pipe. Crazy. Also it was my own pipe which has never had spice in it. (Not that pipe anyway) Makes me think frequent use might result in excretion through the skin. Makes me want to do tons of psychedelics and go give people hugs.
