Individual Differences in Drug Response

Study Description

Individual Differences in Drug Response

Females are increasingly using cannabis, yet remain underrepresented in preclinical and clinical cannabinoid research. This female-specific research plan will test the effects of two recreationally relevant doses of oral THC and placebo in healthy females at two phases of the menstrual cycle. Acute oral THC will be administered in a double-blind and counterbalanced design. Menstrual cycle phase will be determined using blood serum analyses of estradiol and progesterone and self-reported responses. The main hypothesis is circulating estradiol levels are associated with cardiac, neuroendocrine, and subjective THC response. The rationale for the presented work is to better understand the risks of cannabis use, in order to maximize possible medical potential and minimize public health risks. The expected outcome of this work is a deeper understanding of how circulating estradiol levels may associate with response to THC and how the physiological response is associated with the subjective response. Uncovering the individual differences in response to THC will allow for more preventive action against cannabis-induced anxiety, paranoia, and psychosis.

Drug - Dronabinol

THC (Marinol® [dronabinol]; Solvay Pharmaceuticals) will be orally administered in doses of 7.5 mg and 15 mg, in opaque capsules with dextrose filler. Placebo capsules contain only dextrose. These doses of THC are known to produce performance impairments as well as subjective intoxication with little to no adverse reactions in experienced occasional, but non-daily cannabis users (Ménétrey et al., 2005; Issa et al. 2016).

Drug - dextrose

We are administering dextrose to health volunteers for our placebo group
