Users can inhale a little but effective dose of the strong substance. There is no nicotine in the pen. People used to believe DMT could only be taken from a bong or crack-style pipe or injected or combined with an Ayahuasca brew created by an Amazonian shaman. Introducing people to DMT without them having to use a glass pipe—which, for some, might seem like you’re smoking—is a terrific approach by vaping it.
