Warning signs
Seizure, chest pain or severe confusion

There’s no THC conversion

A pinch or puff can be much stronger than the last one. A THC label or home test can’t tell you the dose. Ask a drug-checking service if it can identify what you have.

Watch for poisoning

Avoid mixing or taking more. Have someone sober nearby and keep the package to show responders. Call 911 for chest pain, severe confusion, or a seizure.
