Marijuana for medical use may result in rapid onset of cannabis use disorder

A new study shows that using cannabis products to treat pain, anxiety and depression failed to improve these symptoms while doubling the risk of developing the addictive symptoms of cannabis use disorder.
-
People seeking cannabis to treat symptoms of anxiety and depression were at greatest risk of CUD.
-
Contrary to evidence-based medicine, people with medical marijuana cards choose their own products and dosing, suggesting the need for better controls over dispensing, use, and professional follow-up of these patients.

Cognitive control in young adults with cannabis use disorder: An event-related brain potential study.
07/26/2017 |
Abstract
Contemporary models of substance use disorders emphasize the role of cognitive control, which has been linked to difficulties in resisting the use of substances. In the present study, we measured two aspects of cognitive control, response inhibition (operationalized by a Go/NoGo Task) and performance monitoring (operationalized by an Eriksen Flanker Task), in a group of young cannabis-use disorder (CUD) patients and compared these functions with two control groups (i.e. a group of cigarette smokers and a group of non-smokers). We employed both behavioural and electrophysiological measures. The results indicate that CUD patients displayed reduced NoGo-P3 event-related potentials compared with non-smoking controls, but not compared with smoking controls. In addition, CUD patients were slower on Go trials than both control groups. No other between-group electrophysiological or behavioural differences were observed. These results seem to suggest that CUD patients have problems related to response inhibition, but performance monitoring seems relatively unaffected.
