Change From Baseline in Profile of Mood States (POMS) [ Time Frame: End of study (Baseline - time 0 and approximately 4 weeks later) ]
The POMS measures individuals' mood states. This is a validated scale to measure positive and negative mood states. The POMS contains 30 items and assess six identified mood factors: Tension-Anxiety, Depression-Ejection, Anger - Hostility, Vigor-Activity, Fatigue-Inertia, and Confusion-Bewilderment. Scoring of this instrument provides a global score of 0 to 120 or individual domain scores. Lower scores indicate better mood state. The POMS brief form is a simple self-rating instrument

Descriptive Information
Brief Title  ICMJE Individual Differences in Drug Response
Official Title  ICMJE Differential Female Response to Δ9-tetrahydrocannabinol (THC): The Influence of Estradiol
Brief Summary 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.

Study Type  ICMJE Interventional
Study Phase  ICMJE Early Phase 1
Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Basic Science
Condition  ICMJE Differential Female Response to Δ9-tetrahydrocannabinol (THC): The Influence of Estradiol
Intervention  ICMJE
  • Drug: Dronabinol
    THC (Marinol® [dronabinol]; Solvay Pharmaceuticals) will be orally administered in doses of 10 mg and 20 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
Study Arms  ICMJE
  • Placebo Comparator: Placebo
    Intervention: Drug: dextrose
  • Active Comparator: 10 mg THC
    Intervention: Drug: Dronabinol
  • Active Comparator: 20 mg THC
    Intervention: Drug: Dronabinol
