Phytocannabinoids for the Treatment of Chronic Chemotherapy-Induced Peripheral Neuropathy in Breast and Colon Cancer Survivors
This clinical trial tests how well phytocannabinoids (cannabidiol [CBD] and tetrahydrocannbinol [THC]) work in reducing chronic chemotherapy-induced peripheral neuropathy (CIPN) in breast and colon cancer survivors. Neuropathy is the most common neurological symptom reported by cancer patients due to treatment. A variety of pharmacologic treatments have been evaluated to alleviate CIPN symptoms; however, no definitive treatment has been found to successfully treat all the symptoms of CIPN. Therefore, investigators continue to seek other possible treatment options including cannabis. Phytocannabinoids may be a particularly useful intervention for cancer patients given the limited effective treatments for CIPN. In addition, cannabis-based medicines have become tremendously popular as both cancer patients and clinicians are seeking therapies with fewer potential risks of dependency and other side effects. This trial is being done to provide cancer patients and clinicians with reliable information to help guide their use of phytocannabinoids to manage the tremendous distress and pain experienced by many cancer patients, which impacts their long-term quality of life.

CBD, Nutrient Metabolism and Energy Intake
CBD may affect metabolic control and energy intake. However, there is currently little data regarding these specific outcomes in humans. Therefore, this study will investigate whether a single 300 mg dose of CBD can improve metabolic control following a meal and/or reduce energy intake at a subsequent meal. Healthy, adult volunteers will complete two conditions in a crossover design, comparing outcomes following both CBD and placebo supplementation.

Combined and Separate Effects of Cannabis and Tobacco: Psychomotor, Subjective and Physiological Outcomes
Co-administration of cannabis and tobacco is a common practice, but there is little experimental evidence aimed at understanding the reasons for this prevalence. Some preliminary evidence suggests that tobacco may actually counteract the cognitive-impairing effects of cannabis, and may also increase the subjective ('liking') effects of cannabis, but results are inconclusive. Further, there are no studies into the effects of tobacco on other cannabis-related harms such as driving, or on the ability of tobacco to alter the blood levels of THC, the chemical responsible for the psychoactive properties of cannabis. The purpose of the present study will be to evaluate the effects of tobacco, cannabis or combinations of tobacco and cannabis on driving, cognition, subjective effects and blood THC. Driving will be assessed using a state-of-the-art driving simulator that allows for the safe and objective measurement of the effects of intoxicating substances on driving. Participants will be regular users of cannabis and will be invited to the lab for four counterbalanced test sessions. In these test sessions they will drive the simulator and undergo cognitive tests before and after smoking: 1) cannabis; 2) tobacco; 3) cannabis + tobacco; or 4) placebo. Outcomes will be measured at several time points after smoking the product. Participants will also give blood for determination of levels of THC, and will complete subjective effects questionnaires both before and after smoking the cigarette. This study will be one of the first experimental laboratory studies of the reasons behind co-administration of tobacco and cannabis.

Evaluating the Effects of Cannabis Use and Circulating Cannabinoids on Tumor Infiltrating Lymphocytes in Malignant Melanoma
The goal of this proposal is to determine how cannabinoid use affects the tumor immune microenvironment (TME) of melanoma by correlating TILs with reported cannabinoid use and circulating plasma cannabinoids. The central hypothesis is that cannabinoid use decreases TILs in melanoma in a dose-dependent fashion. This is important because cannabinoid-driven TME changes in melanoma may alter patient outcomes mediated by TILs and response to standard of care ICI treatments.

Acute Effects of Cannabis on Everyday Life Memory
This study will examine the acute effects of cannabis on various aspects of memory. Eligible participants will complete a drug screen followed by baseline measures of cannabis consumption patterns, level of intoxication, euphoria, anxiety, stress, and verbal intelligence. Next, participants will be randomly assigned to inhale vapor from cannabis containing 20mg THC or placebo; both cannabis and placebo will be obtained from the National Institute on Drug Abuse (NIDA). Participants will complete a battery of memory tests including tests of prospective, verbal, visuospatial, autobiographical, source, verbal working, visuospatial working, false, and temporal order memory. Memory tests will be completed across two blocks in a counterbalanced order. Ratings of intoxication, euphoria, anxiety, and stress will be obtained three additional times after drug/placebo administration. The investigators hypothesize that participants who are randomly assigned to inhale cannabis vapor will perform worse on all memory tests than participants who inhale the placebo.

SV2A Density Cannabis Use Disorder
The main purpose of this study is to determine whether hippocampal synaptic vesicle density estimated by hippocampal [11C]APP-311/[11C]UCB-J binding in individuals diagnosed with cannabis use disorder (CUDs) improves with at least 4 weeks of confirmed abstinence from cannabis, in comparison to healthy controls (HCs). Furthermore, any change in synaptic vesicle density will be placed in functional context by measuring verbal memory, which is sensitive to hippocampal function, before and after at least 4 weeks of confirmed abstinence. Finally, the relationship between hippocampal [11C]UCB-J binding in CUDs with measures of cannabis exposure (e.g., age of initiation, cumulative lifetime dose) will be explored.
