Greening out is the experience of feeling sick or ill after consuming too much cannabis, essentially resulting in an overdose of the drug. Unlike alcohol’s effects, greening out can cause dizziness, nausea, anxiety, and, in some cases, vomiting or hallucinations. This reaction can happen with all forms of cannabis products, including smoking, edibles, gummies, or vaping.

Hotboxing is also one of the primary reasons for greening out.

According to National Institute on Drug Abuse (NIDA) In 2022, an estimated 8.3% of 8th graders, 19.5% of 10th graders, and 30.7% of 12th graders reported using cannabis/hashish in the past 12 months.

Research shows that greening out is much more likely to occur if the user has been drinking alcohol before smoking cannabis. Alcohol in the bloodstream can result in a stronger and more unpleasant effect than usual.
