There are several categories of designer drugs, each with distinct effects:
Synthetic cannabinoids (e.g., Spice, K2) mimic THC but can be much stronger. Synthetic cathinones (e.g., bath salts) resemble stimulants like methamphetamine. Designer opioids (e.g., fentanyl analogs) are highly potent and can be lethal in small doses. Phenethylamines (e.g., 2C drugs) have hallucinogenic properties.
