Controlled human evidence

What the evidence actually shows

What we do not know

Those trials do not show trace, inhaled cannabis eucalyptol treats bronchitis, asthma, or COPD.

Safety and interpretation

A certificate of analysis identifies composition, not a safe or effective dose. Inhalation can irritate airways, and heating terpenes can create degradation products.
