How Cannabis Affects the Mind and Body

Endocannabinoid system

The endocannabinoid system (ECS) is a group of receptors located in the brain and throughout the central and peripheral nervous systems. The ECS is involved in a variety of physiological processes including appetite, painsensation, mood, and memory, and in mediating the psychoactive effects of cannabis.

Cannabinoids regulate how cells send, receive, or process messages. Cannabinoids act like a type of “dimmer switch,” slowing down communication between cells.

What happensin the Central Nervous System?

When someone ingests cannabis, THC attaches to cannabinoid receptors in the brain. THC slows down the communication in the EC system, leading to many of the effects noted below.
