Medical marijuanais cannabis that’s prescribed by a physician to treat or provide relief for a medical condition.
Cannabinol, or CBD, is the other cannabinoid, which is used in medical marijuana.
How Does Medical Marijuana Affect the Body?
Marijuana affects the body throughneurotransmitters, which are the chemical messengers of the nervous system.
Various factors can stimulate neurotransmitter activity, initiating a set of physiological responses.
Theendocannabinoid system (ECS)is one of the most important neurotransmitter systems in the body.

The endocannabinoid system is not fully understood.
While everyone has an ECS, medical cannabis’s direct interactions with it may affect individuals differently.
Hemp is a plant that contains 0.3% or less THC.

The two most affected by cannabis are:
THC strongly activates CB1 receptors, triggering a feeling of euphoria.
CBD activates both CB1 and CB2 receptors, although less strongly than THC.
For this reason, CBD has been used to treat pain, anxiety, and seizures.
