2,N,N-Trimethyltryptamine (2,N,N-TMT), also known as 2-methyl-N,N-dimethyltryptamine (2-Me-DMT), is a tryptamine derivative. [1] It is not a psychedelic, but instead produces tactile enhancement and auditory distortion. [1] The drug was invented by Alexander Shulgin and reported in his book TiHKAL (#34). [1]

Effects

2-Me-DMT is claimed to show psychoactive effects at a dosage of 50–100 mg orally, but these are relatively mild compared to other similar drugs. [1] This suggests that while the 2-methyl group has blocked the binding of metabolic enzymes, it is also interfering with binding to the 5-HT2A receptor target that mediates the hallucinogenic effects of these drugs.

The specific effects produced by 2-Me-DMT included tingling, mild stomach rumbling, mild relaxation, skin "alerting" especially on the head and neck, bodily/tactile activation and heightened sensitivity, auditory distortion, and altered tonal perception. [1] There were no visuals, no cloudiness of thought processes, no motor impairment, but sexual activity was said to be enhanced. [1] There were no changes in appetite, no gastrointestinal problems, and no after-effects the next day. [1] The drug was described as not being a psychedelic or psychostimulant, but instead being a specific "tactile stimulant" and sexual enhancer. [1]

Pharmacology

Its affinities (Ki) for the serotonin 5-HT1A and 5-HT2A receptor were 4,598 nM and 15,037 nM, respectively. [2] [3] These affinities were dramatically lower than those of dimethyltryptamine (DMT) in the same study, which were 87 nM and 1,513 nM, respectively. [2] [3] Hence, 2-Me-DMT appears to show approximately 53- and 10-fold lower affinities for the serotonin 5-HT1A and 5-HT2A receptors compared to DMT. [2] [3] In addition, unlike DMT, 2-Me-DMT failed to activate the serotonin 5-HT1A and 5-HT2A receptors. [3] Despite the preceding findings however, 2-Me-DMT induces the head-twitch response, a behavioral proxy of psychedelic effects, in rodents, and does so to a similar magnitude as 5-MeO-DMT. [3]

In studies of other 2-methyltryptamines, specifically 2-methyl-5-MeO-DALT and 2-methyl-5-F-DALT, these compounds had variably reduced affinities for serotonin receptors and, in contrast to 2-Me-DMT, did not produce the head-twitch response. [4]

Sweden's public health agency suggested classifying 2-Me-DMT as a hazardous substance, on May 15, 2019. [5]
