Freebase DMT

Freebase DMT is the pure alkaloidal form of N,N-Dimethyltryptamine, though it is often used in reference to the freebase form of extracts in which the primary--but not only--active is DMT. This is the form of DMT most commonly used for administration by inspiration through heating it to the point of vaporization. The freebase is preferred because there is a larger window between the evaporation point (where vaporization of active product occurs) and the burning point (where pyrolysis destroys it).

In it's pure form with a uniform structure, it can appear as a clear white crystalline product, but it can be yellow and oily or even waxy or clay-like in it's less structured or less pure forms, depending on the manner of crystallization.
