Marijuana and Erectile Dysfunction

The link between marijuana and ED involves tetrahydrocannabinol (THC), the active ingredient in marijuana.

Studies have shown how THC affects the brain. When a person smokes marijuana, THC gets into the bloodstream and travels to the brain and other organs.

When THC reaches the brain, it interacts with proteins called cannabinoid receptors. This interaction triggers cellular reactions that make a person feel “high” and interfere with normal functioning.

It appears that THC might affect the penis the same way.
