Current Primary Outcome Measures ICMJE |
Standard Deviation of Lateral Position (SDLP) in cm [ Time Frame: 0-8 hours ] A measure of lane weaving during simulated driving performance, the standard deviation of lateral position is a standard metric of impairment in driving performance. A score of 0 (perfect score, no deviation) is the minimum score possible and there is no upper threshold score. Higher scores equate to worse performance (more lane weaving).

Official Title ICMJE | The Effect of Delta-8-THC vs Delta-9-THC on Simulated Driving Performance and Measures of Impairment | ||||||||
Brief Summary | Delta-8-THC is an isomer of delta-9-THC that has become widely available due to the legalization of hemp and its derivatives. Very little controlled research has been conducted with delta-8-THC and some research suggests it produces similar effects to delta-9-THC, albeit at lower potency. The present study will evaluate the dose effects of delta-8-THC, compared with delta-9-THC, on simulated driving performance, field sobriety tests, cognitive performance, and biomarkers of exposure to cannabinoids. The results will inform policy and education related to impairment due to acute delta-8-THC exposure via vaporization and oral ingestion. | ||||||||
Detailed Description | The present study will characterize the acute effects of oral and inhaled ∆8-THC, compared with a positive control dose of ∆9-THC and placebo, on subjective drug effects, cardiovascular effects, cognitive performance, simulated driving performance, field sobriety tests, and drug testing outcomes in oral fluid, blood, hair, and urine. Healthy adults with a history of cannabis use will be recruited to participate in a placebo-controlled, within-subject crossover study at the Johns Hopkins Behavioral Pharmacology Research Unit (BPRU). The result will be a comparative pharmacology and toxicology dataset for ∆8-THC and ∆9-THC via both oral ingestion and inhalation, two routes of administration that are predominant in retail products currently being sold across the U.S. This study will provide urgently needed data on the behavioral pharmacology and toxicology of ∆8-THC, a novel cannabinoid that is now widely available, but for which there is little public knowledge or public health messaging. This data will directly inform the impact of ∆8-THC use on drug testing programs, and the comparative effects of ∆8-THC to ∆9-THC can be used to inform regulatory decisions related to public safety and the sale of these products. | ||||||||

Study Design ICMJE | Allocation: Randomized Intervention Model: Crossover Assignment Intervention Model Description: A within-subjects design. At the time of study randomization, participants will be assigned to complete Sub-Study 1 followed by Sub-Study 2, or vice versa, using a counter-balanced randomization sequence. The order in which dose conditions are administered within each sub-study will be randomized across participants because there are too many drug conditions to fully counterbalance dosing within sub-studies at the proposed sample size. Masking: Double (Participant, Outcomes Assessor)Masking Description: Placebo controlled, double blind drug administration Primary Purpose: Basic Science
