Concluding thought from today's Drugs and the Brain lecture:
DMT is a schedule 1 substance according to the Controlled Substances Act. Which means possession of any amount of it is considered a felony by the federal government.
However, DMT is also an endogenous chemical in the human body. Some say it's a metabolite of certain neurotransmitters such as serotonin. Other recent research suggests that it itself is probably a neurotransmitter of some kind. Either way, since we all possess some of this substance, technically, we're all felons.
