Summary

This study looked at how smoking cannabis affects balance, walking, and attention in 25 older women, some with HIV and some without. Participants smoked either a low-THC cannabis cigarette or a placebo, then did walking and thinking tests. The goal was to understand why cannabis users in earlier studies had more falls.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
cannabis (THC cigarettes)
What this could lead to
If successful, this could help explain why some older women who use cannabis have more falls, and guide safer use recommendations.
What could go wrong
This is a small, early-phase study with only 25 participants, so results may not apply to everyone. It looks at short-term effects, not long-term safety.
