Mescaline is found in peyote and San Pedro cactus. It can last much of the day.
Dose context
Clinical studies used measured oral mescaline
Timing
Effects can build for hours

Weight or cup size can’t establish dose
Pure mescaline and cactus
In one study, 200 mg of pure mescaline hydrochloride lasted about 8 hours on average. 400 mg lasted about 11 hours and felt stronger.
Cactus, tea, and extracts vary in strength. Grams of cactus or cups of tea can’t tell you mg of mescaline. Ask a drug-checking service what it can measure.
Wait for effects to build
Effects can build for hours. Don’t take more just because it feels slow. Plan a safe place to stay and avoid driving. Get help if vomiting won’t stop.
