3C-E, also known as 4-ethoxy-3,5-dimethoxyamphetamine or as α-methylescaline (3C-escaline), is a psychedelic drug of the phenethylamine, amphetamine, and 3C families related to 3,4,5-trimethoxyamphetamine (TMA).[1][5][3] It is the amphetamine (3C) analogue of escaline.[1][3]

Use and effects

In his book PiHKAL (Phenethylamines I Have Known and Loved) and other publications, Alexander Shulgin lists 3C-E's dose as 30 to 60 mg orally and its duration as 8 to 12 hours.[1][2][5][3] Per other sources, it has an estimated typical dose of 45 mg orally.[4] The drug has about the same potency as escaline.[1][2][6]

The effects of 3C-E have been described as including strong visuals, closed-eye imagery like bright colors and distinct shapes, complex fantasy, strangeness, unworldliness, and unreality, an eerie state of awareness, fluctuating erotic and anti-erotic feelings, "exquisite sensitivity", heavy body discomfort, feelings of toxicity, nausea, muscle tremors, malaise, and slight teeth clenching.[1] Shulgin concluded that it was a fascinating compound, but that it was a little too heavy on the body for most subjects.[1]

Interactions

Pharmacology

Pharmacodynamics

3C-E is a potent serotonin 5-HT2A receptor agonist and also interacts with other serotonin receptors and targets.[3][5] It produces the head-twitch response, a behavioral proxy of psychedelic effects, in rodents.[7][4]

Chemistry

Synthesis

The chemical synthesis of 3C-E has been described.[1]

Analogues

Analogues of 3C-E include TMA, MEM, 3C-FE, 3C-DFE, and 3C-TFE, among others.[1][3][5]

History

3C-E was first described in the scientific literature by Benington and colleagues in 1954.[8] Alexander Shulgin and colleagues reported an active dose of 40 mg orally based on unpublished findings in a 1978 literature review.[9][10] Subsequently, Shulgin further reported the properties and effects of 3C-E in his book PiHKAL (Phenethylamines I Have Known and Loved) in 1991.[1] The drug was encountered as a novel designer drug in Europe in 2013.[11][12][7]

Society and culture

Canada

It is a controlled substance in Canada under phenethylamine blanket-ban language.[13]

Fewer examples are available in this substitution series, but the α-methyl congener of escaline (3,5-dimethoxy-4-ethoxyphenethylarnine) is virtually equipotent to escaline (Shulgin and Shulgin, 1991).
