Summary

This study looks at whether regular cannabis users can adjust how much they vape when using high-potency concentrates (30%, 60%, and 90% THC). Researchers will measure blood THC levels, puffing behavior, and subjective feelings of intoxication. The goal is to understand if people naturally limit their intake with stronger products, which could inform safety regulations.

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 concentrates at 30%, 60%, and 90% potency)
What this could lead to: If successful, this study could provide evidence to guide regulations on high-potency cannabis products, potentially reducing public health risks like addiction and psychosis.
What could go wrong: This is a small, early-phase study with only 48 participants, so results may not apply to all users. It focuses on acute effects, not long-term harms.
