Well you have the MAOIs in there, so that it is not so critical to vape all the DMT at once, as you have to do otherwise. Also the duration will be much shortened...
But you can do it...and then have to handle it accordingly (trying to smoke all at once).
I claim not that this is the truth. As this is just what got manifested into my mind at the current position in time on this physical plane. So please feel not offended by anything I say.
