Mescaline toxicity
(Redirected from Mescaline)
Background
- Psychedelic phenethylamine , naturally occurring in the peyote cactus (Lophophora williamsii) and other cacti
- Similar to, but chemically distinct from and less potent than LSD
- Thought to be a serotonin agonist
- Sold as dried cactus parts or "buttons"
- Used in religious ceremonies by some indigenous Central and South american peoples.
Clinical Features
- Onset 30-60 minutes, lasts 5-12 hours (though wide individual variability)
- Euphoria, energy, esoteric/spiritual experiences
- Altered sensorium, altered sense of time, extreme focus or distractibility, hallucinations
- Nausea/vomiting, abdominal pain
- Adrenergic stimulation: mydriasis, mild tachycardia, mild hypertension, hyperthermia
- Dizziness, headache
