“…For tests of processing speed and psychomotor effects, it has been recommended to use the Digit Symbol Substitution Task, which is a timed paper-and-pencil task, that involves matching symbols with digits (Greenwald and Stitzer, 2000). Measures of the speed of finger tapping and arm and leg movements have also been shown to be sensitive to cannabis exposure (Hitchcock et al, 2021). Lastly, the Paced Auditory Serial Attention Test offers a measure of working memory in addition to attention and information processing speed (Spindle et al, 2018;Arkell et al, 2019).…”

Cannabis is one of the oldest and widely used substances in the world. Cannabinoids within the cannabis plant, known as phytocannabinoids, mediate cannabis' effects through interactions with the body's endogenous cannabinoid system. This endogenous system, the endocannabinoid system, has important roles in physical and mental health. These roles point to the potential to develop cannabinoids as therapeutic agents, while underscoring the risks related to interfering with the endogenous system during non-medical use. This scoping narrative review synthesizes the current evidence for both the therapeutic and adverse effects of the major (i.e., Δ9-tetrahydrocannabinol and cannabidiol) and lesser studied minor phytocannabinoids, from nonclinical to clinical research. We pay particular attention to the areas where evidence is well-established, including analgesic effects after acute exposures, and neurocognitive risks after acute and chronic use. In addition, drug development considerations for cannabinoids as therapeutic agents within the United States are reviewed. The proposed clinical study design considerations encourage methodological standards for greater scientific rigor and reproducibility, ultimately, to extend our knowledge of the risks and benefits of cannabinoids for patients and providers. Significance StatementThis work provides a review of prior research related to phytocannabinoids, including therapeutic potential and known risks in the context of drug development within the United States.
