Rasta is no Shaman. I would argue its a barrier to consciousness and would remind ones of a large population of Rastafari that wouldn't even burn ganja. Natural ital living. Hallucinations and consciousness are automatically opposed. I've yet to meet a Rasta who would at least openly encourage such behaviour. Fyah on drug from caffeine to lsd....which is basically what peynote is.
Not to mention the medical effects. From the medical poisons database:
Revised 12/2008 Checked 6/2014
Type of Product
A hallucinogenic phenylethylamine, structurally similar to amfetamine, derived from the peyote cactus (Lophophora williamsii) and the San Pedro cactus (Trichocereus pachanoi). Mescaline is also synthetically manufactured.
Bad seed, big chief, button, mescal, moon tops, peyote.
Caution: using a slang term to try and identify a drug of abuse is potentially dangerous since there are many regional variations and the terms change over time.
Tablet or capsule - usually 200 mg - 500 mg
'Button' - approx. 45 mg
Various - 'buttons' are whole dried cactus tops; chopped buttons, powder, or browny-grey liquid extract.
Synthetic mescaline is available as a white or brown crystalline powder.
Caution: The purity of the ingredients in legal highs and street drugs may vary greatly.
Few fatal cases have been reported (Reynolds & Jindrich, 1985, Nolte & Zumwalt, 1999), although suicidal thoughts can develop. Sympathomimetic effects are thought to be due to a centrally-mediated action, possibly by increasing serotonergic and noradrenergic CNS activity.
All children who have ingested any amount of this preparation should be referred to an Emergency Department.
Nausea, vomiting (which may be forceful), and abdominal cramps are common, usually occurring within 30 to 60 minutes of ingestion and before onset of hallucinogenic effects.
Sympathomimetic effects (mild in adults, more severe in children) - dilated pupils, blurred vision, headache, dizziness, tremor, paraesthesiae, hyperventilation and drowsiness.
Tachycardia (bradycardia with large doses), mild hypertension, rarely palpitations and chest pain.
Psychomimetic effects are most pronounced 4-6 hours post ingestion and usually resolve within 12 hours.
Hallucinogenic effects similar to those of LSD may occur.
Some users experience “flashbacks”, or hallucinogen persisting perception disorder (HPPD), which are reoccurrences of hallucinations long after ingesting the drug. The causes of these effects, which in some users occur after a single experience with the drug, are not known.
