4-D (psychedelic)

4-D, or 3,5-methoxy-4-trideuteromethoxyphenethylamine, is a lesser-known psychedelic drug. It is one of the only phenethylamines that contains Deuterium, the other being Beta-D. It is also the 4-trideuteromethoxy analogue of 2C-H. It exists as a sulfate salt or a hydrochloride salt. 4-D was first synthesized by Alexander Shulgin. In his book PIHKAL (Phenethylamines I Have Known and Loved), the dosage is listed as approximately 200-400 mg for the sulfate salt, and 178-356 mg for the hydrochloride salt. 4-D lasts for approximately 12 hours. It causes closed-eye visuals, mild open-eye visuals, color distortion, and mydriasis. Very little data exists about the pharmacological properties, metabolism, and toxicity of 4-D.
