Cannabinoid Supplementation on Vascular and Cognitive Function

October 21, 2019 updated by: Phil Ainslie, University of British Columbia

The Effects of Cannabinoids on Vascular and Cognitive Function in Young and Old Healthy Adults.

Cannabidiol (CBD) is a bioactive cannabinoid compound in marijuana (cannabis sativa), but unlike Δ9 tetrahydrocannabinol (THC), lacks the psychoactivity effect of THC. Available evidence suggests that there are marked therapeutic CBD effects for diverse disease processes including inflammation, cancers, psychosis, and epileptic seizures. The purpose of this study, in both younger and older healthy humans, is to improve our understanding of how CBD might control and regulate blood vessel health as well as cognitive and exercise performance.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
