Using Cannabis While Drinking May Lead to Riskier Behavior

Young adults often use alcohol and cannabis together, a behavior that may dull the perceived negative effects of drinking and increase the risk of alcohol-related harm. A recent study found that simultaneous use can reduce users’ awareness of alcohol’s effects, potentially leading to alcohol use disorder and dangerous behaviors like drunk driving.

Cannabis Terpenes Offer New Hope for Chronic Pain, Fibromyalgia

New research has identified cannabis-derived terpenes—compounds that give plants their distinctive aroma—as effective treatments for fibromyalgia and post-surgical pain. In preclinical mouse models, terpenes such as geraniol and linalool significantly reduced chronic pain, providing promising alternatives to opioid medications and avoiding THC's psychoactive side effects.

How CBD Modulates THC’s Impact on the Brain

Researchers have identified how CBD interacts with cannabinoid receptors to mitigate the negative effects of THC, the psychoactive component of cannabis. Unlike THC, which fully activates the receptor and causes side effects like memory loss and addiction, CBD acts as a modulator, fine-tuning receptor activity.
