A Study to Investigate the Bioavailability and Skin Absorption of CBD and THC From GT4 Technology in Healthy Adults
The bioavailability of cannabinoids differs greatly for different routes of administration. When applied topically to the skin, they are absorbed through the skin or hair follicles while interacting with receptors to provide localized effects. To gain more information on the potential of this route of administration in therapeutic applications, this open-label study will investigate the skin absorption and bioavailability of CBD and THC delivered trans-dermally.

THC Memory & Reward Learning Pilot
Tetrahydrocannabidiol (THC) is the psychoactive chemical in cannabis that makes people high. This study aims to dissect acute impairment of various forms of memory and learning by THC in cannabis compared to placebo. Impairment will be assessed via a short cognitive test battery and then subjects will complete four tasks in the fMRI scanner.

Standardized Field Test for Marijuana Impairment II
This research responds to NHTSA's request with a proposal to increase our understanding of smoked cannabis' (CNB's) acute effects on driving-relevant cognition and simulated driving performance, the persistence of these deficits over the hours after use, and the influence of prior experience with CNB on these effects. This extension study will aim to further investigate marijuana impaired behavior, using a similar design to our previous NHTSA Examine the Feasibility of a Standardized Field Test for Marijuana Impairment and the prior NIDA Neuroscience of Marijuana-Impaired Driving award, that used similar techniques and measures to quantify marijuana impaired automobile driving. We will be utilizing tasks and assessments that were shown to be strong indicators for cognitive and driving impairment in our NHTSA study.

The Effect of Medical Cannabis on Tics, Premonitory Urge and Psychiatric Comorbidity in Adults With Tourette Syndrome
Medical cannabis (MC) is a standard treatment in Israel to adults with resistant Gilles de la Tourette syndrome (GTS). While small randomized control trials assessed THC efficacy on tics and premonitory urge, only small retrospective studies assessed MC efficacy and tolerability in GTS. Herein, By using an open-label, prospective design, our aim is to determine the preferred method of use, efficacy and tolerability of 12 weeks of treatment with MC in adult patients with GTS.

Fire Dragon Pot Moxibustion
Insomnia in perimenopausal women is normal. Studies have shown that insomnia occurs in 75-81% of perimenopausal women and is 2.4 times more common than in premenopausal participants. Western medicine often uses sedative sleeping drugs in the treatment of insomnia in perimenopausal women, which have better effects but have more side effects, and whether they are suitable for long-term application is still controversial. Non-pharmacological traditional therapies in Traditional Chinese Medicine have achieved significant clinical efficacy in the treatment of perimenopausal insomnia patients in recent years. This study aims to explore the efficacy of auricular point seed burying combined with fire dragon pot moxibustion in the treatment of the insomnia symptoms of perimenopausal women.

Effect of Medical Cannabis for Non-motor Symptoms of Parkinson's Disease
Medical cannabis (MC) is a standard treatment in Israel to Parkinson's disease (PD) patients suffering from pain. Nevertheless, it is not known about MC effectiveness for other non-motor symptoms of the disease. Our aim is to prospectively observe patients with PD before and after initiation of MC, for non-motor symptoms effect. In specific, relying of data from multiple sclerosis patients and basic science showing cannabinoid receptor 1 (CB1) is abundantly expressed in the sub epithelial layer of the bladder, we will explore the impact of MC on bladder function and urinary symptoms.

Evaluation of Effects of CBD Products on Anxiety Among U.S. Women
The investigators will conduct a retrospective cohort analysis of a consumer trial conducted by Rae Wellness. The trial took place between October 15, 2020 and December 30, 2020 and involved 1350 U.S. women who used in-home use tests (IHUT) of various Cannabidiol (CBD) products. Participants were randomized to one of 9 groups: 8 groups received one of 8 different CBD products in the mail, and one group served as the control and did not consume any CBD product. The CBD products varied by method of delivery, concentration of Tetrahydrocannabinol (THC), and dosage of CBD. Participants were asked to use the product once daily for 60 day and to complete health questionnaires at baseline, 30 days and 60 days.

Cannabis and Aging
With increased availability and use of cannabis by older adults aged ≥ 50 years, a rigorous evaluation of the benefits and risks of cannabis use in these individuals is necessary. Our proposed project will investigate whether older adults who initiate cannabis use after the age of 50 are at an increased risk of fall and what are the underlying mechanisms. We will measure motor and cognitive function in older cannabis users and nonusers and we will use positron emission tomography to determine brain activity and how it is associated with fall risk.

CBD for Sleep in People With HIV
This study will obtain preliminary information about whether, and at what dose, cannabidiol (CBD) may help with insomnia in people living with human immunodeficiency virus (HIV). The study will be a 5-week randomized, double-blind placebo-controlled phase II trial using daily oral CBD doses between 50mg and 600mg. Sleep problems will be measured using a wrist-worn device and by self-report. Performance on tests of thinking skills will be compared before and after CBD/placebo treatment. Positive study results will provide support for the use of CBD as a potential treatment for insomnia.

Cannabis as a Complementary Treatment in Multiple Sclerosis
Multiple sclerosis (MS) is an inflammatory disease of the central nervous system (CNS) afflicting over 77,000 Canadians. Unfortunately, the therapeutic arsenal to relieve MS symptoms is limited. It is therefore essential to develop better approaches to treat the symptoms of MS. The use of cannabis for recreational purposes is now legal in Canada. However, for many years, people with Multiple Sclerosis (PwMS) have used cannabis either to relax, to reduce pain and spasticity, or to improve sleep and daily functioning. Currently, there is little scientifically established evidence that cannabis works on these symptoms in people with MS. It is therefore important to carry out studies to better understand the efficacy Δ-9-tetrahydrocannabinol (THC), and cannabidiol (CBD) on MS symptoms . THC is known for its analgesic, neuroprotective and anti-inflammatory properties and CBD seems to have positive effects on anxiety and cognitive abilities (memory, concentration).
For this study, investigators hypothesize that administering different doses of THC alone, CBD alone, and THC and CBD combined will result in a significant beneficial effect on spasticity relief compared to placebo.

Topical CBD for Musculoskeletal Pain
Rationale: CBD is commonly being used as an over-the-counter treatment for musculoskeletal pain; however, no clinical trial has been performed to establish efficacy of CBD in humans for musculoskeletal pain.
Hypothesis: CBD is more effective than placebo for relieving pain and improving patient-reported outcomes for musculoskeletal pain.
Study Design: The study design with be a double-blind, randomized controlled trial with crossover. Treatment will be blinded to the subjects and investigators. Patients will be randomly assigned 2 weeks of the CBD or control and then crossover to the other condition for 2 additional weeks. Patients will apply the CBD or control cream to the affected area twice daily (approximately every 12 hours) for 1 hour. Subjects will be advised to observe for physiologic changes, skin changes, or other adverse effects.
