pb-22

PB-22 is a synthetic cannabinoid, a type of designer drug that mimics the effects of THC, the active component in cannabis. It acts as a potent agonist at the CB1 and CB2 cannabinoid receptors in the brain and body. PB-22 has appeared in some herbal incense or “spice” products marketed as legal highs, though it is now controlled or banned in many countries due to safety and toxicity concerns.
