Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Eligible participants will undergo a full day screening visit, if still eligible they will come to Hartford Hospital in Hartford, Connecticut to take part in the full study. Participation requires overnight stays between each of the five study visits. On each of the study days participants are dosed with either a low dose of THC marijuana, a high dose of THC marijuana or placebo marijuana, (the low and high doses are repeated once each, order in which the study drug is given is double blind and chosen at random.)
