Science for Pot Smokers

by Rachel Baker on September 9, 2013

Here’s an interesting story about the science of why people love to get high.

Marijuana is not magic. Marijuana (botanical name, cannabis) affects the human body because the plant-based cannabinoids in marijuana, once ingested, can “plug into” the cannabinoid receptors that are used by the cannabinoids made by our own bodies.

It’s not just people that have cannabinoid systems. All mammals have them. All creatures do, except bugs. Although cannabinoid systems can utilize the plant-based cannabinoids in marijuana, the cultivation and preservation of cannabinoid systems by the evolutionary process has nothing to do with pot. The cannabinoid receptor appeared on the planet at least 550 million years before marijuana.
