What Are Synthetic Cannabinoids and Why Are They So Dangerous?

Synthetic cannabinoids, sometimes called spice, K2, or by chemical names like Pinaca, are man-made chemicals designed to mimic the effects of THC, the active compound in marijuana. The similarity ends there.

Natural marijuana has never been directly linked to a fatal overdose. Synthetic cannabinoids kill people regularly. The chemical compounds used in synthetic drugs are engineered and re-engineered constantly, often specifically to evade detection and drug testing. Each new formulation tends to be more potent than the last, and the human body responds to these chemicals in ways that are far more severe and unpredictable than to natural cannabis.

The symptoms of a synthetic cannabinoid overdose can include seizures, cardiac arrest, kidney failure, and loss of consciousness within minutes of exposure. Narcan, the medication used to reverse opioid overdoses, does not affect synthetic cannabinoid overdoses, which means medical staff at correctional facilities have extremely limited tools to intervene once an inmate is in crisis.

In the Cook County jail outbreak, inmates were dying in their cells before anyone understood what was happening. The drug was arriving on paper that looked completely ordinary, and the facilities had no detection system in place for it initially.

Law enforcement officials who have dealt with this firsthand describe synthetic cannabinoids as potentially more dangerous than fentanyl if the drug-soaked paper method were to spread beyond correctional facilities into the general population. The fact that it is invisible, odorless, and undetectable by standard means makes it uniquely difficult to combat.
