NCT ID: NCT04429568 Recruiting - Nicotine Dependence Clinical Trials

THC Crossover Study

TRDRP
Start date: October 30, 2020
Phase: N/A
Study type: Interventional

This is a randomized, crossover study enrolling experienced dual cannabis-tobacco smokers (N=18) to describe the differences in THC and toxicant exposure, examining pharmacokinetic, subjective, and cardiovascular effects from smoking and vaping dry herb cannabis. This study will also examine the differences in toxicant exposure and cardiovascular disease risk between smoking cannabis and smoking tobacco cigarettes.

NCT ID: NCT04325958 Recruiting - Cannabis Clinical Trials

Age Differences in the Effects of Cannabis on Simulated Driving

ADCUF
Start date: March 27, 2024
Phase: N/A
Study type: Interventional

Epidemiological studies suggest that the use of cannabis is associated with an increase in the risk of motor vehicle collisions. It is also known that younger users may be at increased risk for motor vehicle collisions. Further, the frequency with which cannabis is used may be an important variable in determining the effects of cannabis on driving. The purpose of the present study will be to investigate the effects of cannabis on simulated driving in young as compared to middle-aged drivers. Half of the participants will be occasional users of cannabis and half will be frequent users of cannabis.

NCT ID: NCT03078309 Recruiting - Clinical trials for Retinitis Pigmentosa

The Effects of Cannabis on Visual Functions in Healthy and Retinitis Pigmentosa Patients

Start date: September 1, 2018
Phase: Early Phase 1
Study type: Interventional

Medical Marijuana is used widely, and its effects on the visual system and the function of the retina have not been investigated thoroughly. Some evidence suggests that cannabinoids may be beneficial in certain degenerative diseases of the retina. The purpose of the study is 1. To determine whether cannabis derivatives affect the visual functions in healthy adults 2. To examine the effect of cannabis derivatives on the retina of retinitis pigmentosa patients

NCT ID: NCT02817698 Recruiting - Smoking Clinical Trials

Imaging the Neurochemistry of Drug Addiction With PET

Start date: November 29, 2017
Phase: Early Phase 1
Study type: Interventional

The investigators' project has two overarching goals. 1) The investigators will use newly developed positron emission tomography (PET) technology to investigate the dopaminergic neurochemistry of drugs of abuse including marijuana, traditional cigarettes, and cocaine, and 2) The investigators will extend PET technology to an additional neurotransmitter system - namely, the opioid-ergic system, using the same drugs of abuse.

NCT ID: NCT02811510 Recruiting - Cannabis Clinical Trials

Gender Related Differences in the Acute Effects of Delta-9-Tetrahydrocannabinol in Healthy Humans: Sub-Study I

THC-Gender-I
Start date: June 2016
Phase: Phase 1
Study type: Interventional

The purpose of the study is to characterize the acute effects of cannabinoids in women relative to men and to begin probing the mechanisms that may underlie gender differences.

NCT ID: NCT02781519 Recruiting - Cannabis Clinical Trials

Gender Related Differences in the Acute Effects of Delta-9-Tetrahydrocannabinol in Healthy Humans

THC-Gender
Start date: June 2015
Phase: Phase 1
Study type: Interventional

The purpose of the study is to characterize the acute effects of cannabinoids in women relative to men and to begin probing the mechanisms that may underlie gender differences.
