For your term paper, as a topic, you should choose either a plant/substance (it is acceptable to do your term paper on a synthetic substance not of biological origin) and focus on that, or on a more general topic, such as “the use of hallucinogens in religious movements,” “hallucinogens and the origins of religion,” “drug interdiction policy and hallucinogens,” “the use of psychotropics in psychotherapy,” etc., etc. So your term paper could be on ayahuasca/DMT, bufo toads/bufotenine, a synthetic (MDMA, katamine, etc.), or on a general topic covering hallucinogens. Discuss cultural, medical, religious, therapeutic, recreational, and other uses of the substance; also discovery, historical usage, isolation of active ingredients, etc.
