Thirty purposively selected volunteers interested in cannabis-based care were assigned to three groups of ten and consumed drip tea containing 3%, 5% or 7% cannabis leaf nightly for one week. Happiness scores increased from baseline, with the 7% formulation producing the highest score. Because the study was small, non-randomized and lacked a placebo or non-cannabis control, it cannot establish efficacy or safety.
Key findings
- Happiness scores increased after one week. • The 7% formulation produced the highest score among the three groups. • Evidence came from only 30 volunteers without a control group.
Why this matters globally
This is an exploratory signal, not a recommendation for use or a treatment claim. Randomized controlled trials with cannabinoid measurement and adverse-event monitoring are needed.
Thai researcher contribution
The Sakon Nakhon Rajabhat University team examines a Thai herbal-beverage practice in the medical-cannabis context.
Limitations to consider
The study was small, purposively sampled, non-randomized, uncontrolled, only one week long, and vulnerable to expectation effects in self-reported happiness.
