Synthetic cannabinoids are man-made chemicals designed to mimic the effects of natural cannabis compounds. They are often sprayed onto plant material and sold as "herbal incense" or "spice." Users may seek these products for a similar high to marijuana, but the effects can be unpredictable and much stronger, leading to serious health risks. These substances interact with the same brain receptors as THC, the active ingredient in cannabis. However, because they are not regulated, their potency and composition can vary widely. This unpredictability can result in dangerous side effects, including anxiety, hallucinations, and even severe medical emergencies.
