Abstract Background Trends in cannabis use suggest a global increase in the past decade. Current evidence associates cannabis use with an increased risk of psychosis. This association has prompted a growing research interest in the association between cannabis use and psychiatric disorders, especially psychotic disorders. This study aims to gain a better understanding of the effect of cannabis...
Cannabis and classic psychedelics are controlled substances with emerging evidence of efficacy in the treatment of a variety of psychiatric illnesses. Cannabis has largely not been regarded as having psychedelic effects in contemporary literature, despite many examples of historical use along with classic psychedelics to attain altered states of consciousness. Research into the “psychedelic”...
Medical cannabis (MC) is increasingly used for chronic pain, but it is unclear how it aids in pain management.

Theoretical models of addictive behavior suggest that subjective effects serve as a mechanism through which substance use disorders develop. However, little is known about the subjective effects of simultaneous alcohol and cannabis use, particularly whether simultaneous use (a) heightens specific subjective effects or (b) is related to unique subjective effects relative to single-substance...

This study analyzed the self-regulation behaviors of drivers under the influence of cannabis and its relationship with road complexity and some driver traits, including visual deterioration. Cannabis is the illicit drug most often detected in drivers; its use results in significant negative effects in terms of visual function. Self-regulation behaviors involve the mechanisms used by drivers to...

While the legal status and public perception of cannabis are currently changing in many countries, one of the important considerations from a public health viewpoint is its potential association with adverse health outcomes such as the development of psychosis. We conducted an umbrella review of systematic reviews and meta-analyses using the AMSTAR-2 to assess the quality of included reviews....
There is increased risk of psychosis associated with cannabis use disorder and the interaction of THC with dopamine neurotransmission is complex. It is important to investigate the recovery from cannabis-induced psychosis and its effects on the brain’s dopamine neurotransmission. This study was to evaluate dopamine receptor D 2 availability in the striatum (caudate/putamen) in recently...

Approximately 200 million people consume cannabis annually, with a significant proportion of them using it chronically. Using experience sampling, we describe the effects of chronically getting high on emotions, motivation, effort, and self-regulation in everyday life. We queried chronic users (N=260) 5 times per day over 7 days (3,701 observations) to assess immediate effects of getting high...
Cannabis sativa L. is a widely used recreational drug in Togo, especially among young people. However, little is known about its chemical composition in Sub-Saharan Africa, and specifically in Togo. This study aimed to determine the levels of phytocannabinoids, specifically Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD), in cannabis samples collected from various towns in Togo using gas...
