TOMSO (2-methoxy-4-methyl-5-methylsulfinylamphetamine) is a lesser-known psychedelic drug and a substituted amphetamine. TOMSO was first synthesized by Alexander Shulgin. In his book PiHKAL, the dosage range is listed as 100–150 mg, and the duration listed as 10–16 hours.^[1] TOMSO is inactive on its own; it is activated with the consumption of alcohol. It produces intense time distortion and a threshold. Very little data exists about the pharmacological properties, metabolism, and toxicity of TOMSO.
