Marijuana contains a complex mix of chemicals, some with medicinal effects, others with an effect that, well, have led it to be classified as a controlled substance. The cannabinoid THC, the primary active ingredient, seems to do both. It’s responsible for many of the psychoactive qualities of marijuana, but is also a potent analgesic, blocking a variety of pain. A study that was released over the weekend, however, indicates that some of its painkilling effects are mediated via a receptor that wasn’t previously known to interact with the cannabinoids. In the process of characterizing this new receptor, the authors find a chemical that blocks pain, but has no apparent psychoactive effects.
