Rick Simpson oil (RSO) is unique in that it contains higher levels of tetrahydrocannabinol (THC) than other medical cannabis extracts.

Although there is some evidence to support the use of cannabis for aiding cancer treatment, the medical community needs more direct evidence of its safety and effectiveness in humans before making any firm claims.

A new target for marijuana

Cellular-level changes to a part of the brain’s reward system induced by chronic exposure to the psychoactive component of marijuana may contribute to the drug’s pleasurable and potentially addictive qualities, suggests a study in young mice published in JNeurosci. The results could advance our understanding of marijuana’s effects on the developing brain as the drug’s rapidly changing legal status increases its recreational and medical use in the United States.

Drugs of abuse impact the ventral tegmental area (VTA) of the brain, which is rich in dopamine neurons. Using juvenile and adolescent mice, Jeffrey Edwards and colleagues investigated the effects of tetrahydrocannabinol (THC), the chemical in marijuana responsible for its effects on cognition and behavior, on VTA GABA cells, an understudied inhibitory cell type in the reward system that regulates dopamine levels.
