Synthetic cannabinoids sold as K2 or Spice are illegal in New York State and have been linked to severe, sometimes fatal health effects in teens, including psychosis, seizures, coma, and poisoning from opioids and other toxic drugs.
What Is K2/Spice?
K2/Spice products are dried plant material sprayed with lab‑made chemicals that stimulate the same brain receptors as THC, but often much more powerfully.
They are frequently marketed as “herbal incense,” “potpourri,” or “legal weed,” using bright, youth‑appealing packaging and misleading labels like “not for human consumption” to avoid regulation.
Because manufacturers constantly change the chemical formulas to evade laws, the same brand name can contain completely different—and more dangerous—compounds from one batch to the next.
Health Dangers for Adolescents
Teens who use synthetic cannabinoids are far more likely than cannabis users to end up in emergency departments with seizures, coma, and the need for intubation or ICU care.
Reported short‑term effects include extreme agitation, hallucinations, violent or bizarre behavior, panic, very high blood pressure and heart rate, chest pain, kidney injury, and seizures.
In New York and other states, K2 use has been tied to “zombie‑like” states, loss of consciousness, and sudden death.
Contamination and Overdose Risk
Testing in New York has found some K2 packets from convenience stores contaminated with powerful synthetic opioids, greatly increasing the risk of overdose and death.
Other batches have contained synthetic stimulants (“bath salts”), MDMA‑type drugs, and designer benzodiazepines, so a young person who thinks they are using “fake weed” may actually be ingesting a toxic drug cocktail.
Because the chemicals are unevenly sprayed on the plant material, even a few extra puffs from the same packet can push someone from “high” to seizure, psychosis, or collapse.
Impact on the Teen Brain and Mental Health
Adolescents and young adults are the age group most likely to use synthetic cannabinoids, which is especially concerning because their brains are still developing.
Research on key K2 chemicals (such as JWH‑018 and AB‑FUBINACA) shows that exposure during adolescence can lead to long‑term anxiety, problems with information processing, and changes in brain cells and circuits into adulthood.
Clinically, synthetic cannabinoid use has been associated with panic attacks, severe anxiety, and psychotic symptoms that can last beyond the immediate drug effects.
New York Law and Retail Sales
In New York State, it is illegal to possess, sell, offer to sell, or manufacture synthetic cannabinoids, and each individual packet can count as a separate violation under state public health laws.
Retailers caught selling K2 can face fines for each packet, loss of licenses, and in some areas criminal charges and business closure.
Despite being banned for more than a decade, K2 products are still being found in gas stations, bodegas, and smoke shops, often with packaging that targets young people and without any safety testing or accurate labeling.
