And now, on a lighter note:

Ask the doctor:

WHY DO YOU GET THE MUNCHIES WHEN YOU ARE STONED?

The main active chemical in marijuana is THC (delta-9-tetrahydrocannabinol). THC falls in the category of chemicals called cannabinoids. Molecules called endocannabinoids, marijuana-like chemicals that are present in our brains, bind with receptors in the hypothalamus and activate hunger. These endocannabinoids in the brain activate cannabinoid receptors, which are responsible for maintaining food intake. The chemicals from marijuana bind to these same receptors and cause the ?munchies.? Far out, huh?
