Mescaline Mescaline Mescaline (3,4,5-trimethoxyphenethylamine) is a naturally occurring psychedelic alkaloid of the phenethylamine class, known for its hallucinogenic effects comparable to those of LSD and psilocybin. It occurs naturally in the peyote cactus ("Lophophora williamsii"), the San Pedro cactus ("Echinopsis pachanoi"), the Peruvian torch ("Echinopsis peruviana"), and other members of the Cactaceae plant family. It is also found in small amounts in certain members of the Fabaceae (bean) family, including "Acacia berlandieri". However those claims concerning Acacia species have been challenged and have been unsupported in additional analysis. Peyote has been used for at least 5,700 years by Native Americans in
Naturally aspirated engine Naturally aspirated engine A naturally aspirated engine is an internal combustion engine in which oxygen intake depends solely on atmospheric pressure and does not rely on forced induction through a turbocharger or a supercharger. Many sports cars specifically use naturally aspirated engines to avoid turbo lag. In a naturally aspirated engine, air for combustion (diesel cycle in a diesel engine or specific types of Otto cycle in petrol engines—namely petrol direct injection), or an air/fuel mixture (traditional Otto cycle petrol engines)—is drawn into the engine’s cylinders by atmospheric pressure acting against a partial vacuum that occurs as the piston travels
