Which cannabinoid is primarily known for its psychoactive effects?

The cannabinoid primarily recognized for its psychoactive effects is THC. Tetrahydrocannabinol (THC) is the main psychoactive constituent of cannabis, and it is responsible for the "high" that users experience. This compound interacts with the endocannabinoid system in the brain by binding to cannabinoid receptors, particularly the CB1 receptors, which leads to various effects, including altered perception, mood changes, and increased appetite.

In contrast, CBD, CBN, and CBC are cannabinoids that do not produce the same psychoactive effects as THC. CBD, for example, is known for its potential therapeutic benefits without inducing a "high," making it popular for medicinal applications. CBN, which is derived from the degradation of THC, also does not have significant psychoactive properties, and CBC, while having potential therapeutic effects, is likewise non-psychoactive. This distinction is important in understanding the different uses and effects of cannabinoids in both recreational and medicinal contexts.
