===Essential amphetamines=== <!-- Note: a redirect, [[Essential amphetamines]], links to this subsection -->
The "Essential Amphetamines" are what Shulgin describes as ten amphetamines that differ from natural products such as [[safrole]] or [[myristicin]] by an amine group ([http://www.erowid.org/library/books_online/pihkal/pihkal157.shtml ''PIHKAL'' Entry #157 TMA]). The list consists of:

* [[Paramethoxyamphetamine|PMA]] (''para''-'''m'''ethoxy-'''a'''mphetamine)
* [[2,4-DMA]] (2,4-'''d'''i'''m'''ethoxy-'''a'''mphetamine)
* [[3,4-DMA]] (3,4-'''d'''i'''m'''ethoxy-'''a'''mphetamine)
* [[3,4-Methylenedioxyamphetamine|MDA]] (3,4-'''m'''ethylene'''d'''ioxy-'''a'''mphetamine)
* [[3-Methoxy-4,5-methylendioxyamphetamine|MMDA]] (3-'''m'''ethoxy-4,5-'''m'''ethylen'''d'''ioxy-'''a'''mphetamine)
* [[MMDA-3a]] (2-'''m'''ethoxy-3,4-'''m'''ethylen'''d'''ioxy'''a'''mphetamine)
* [[MMDA-2]] (2-'''m'''ethoxy-4,5-'''m'''ethylen'''d'''ioxy'''a'''mphetamine)
* [[Trimethoxyamphetamine|TMA]] (3,4,5-'''t'''ri'''m'''ethoxy'''a'''mphetamine)
* [[Trimethoxyamphetamine|TMA-2]] (2,4,5-'''t'''ri'''m'''ethoxy'''a'''mphetamine)
* [[DMMDA]] (2,5-'''d'''i'''m'''ethoxy-3,4-'''m'''ethylene'''d'''ioxy'''a'''mphetamine)
* [[DMMDA-2]] (2,3-'''d'''i'''m'''ethoxy-4,5-'''m'''ethylene'''d'''ioxy'''a'''mphetamine)
* [[Tetramethoxyamphetamine|TeMA]] (2,3,4,5-'''te'''tra'''m'''ethoxy'''a'''mphetamine)

Not all of these chemicals are bioassayed in ''PIHKAL''; some are merely mentioned.
