Kind: research · Impact: low

## In brief

- A study of more than 17,700 US adults examined cannabis use across multiple forms.
- People who used cannabis in multiple forms had markedly higher rates of daily use and addiction symptoms than those who mainly used one method.
- Nearly 67% of those who used almost every form reportedly met criteria for addiction-related symptoms.

## Why it matters

The findings suggest that the number of cannabis forms a person uses may be a warning sign of heavier use and addiction, which could help clinicians and public health researchers identify at-risk users.
