Psychoactive Research chemicals are new synthetic substances that are structurally similar to the original drug, while being functional analogs. Research on the effects of, and treatment for, abuse of these drugs is limited due to the fact that they’re fairly new and have avoided mainstream notice. Research chemicals do not have a lot of human consumption data, and thus harm-reduction and special care should be taken if choosing to ingest them.

Psychedelics are drugs which cause profound changes in a one’s perceptions of reality, otherwise known as hallucinations. While under the influence of hallucinogens, users might see images, hear sounds or feel sensations. These chemicals offer some of the most intense psychological experiences and care should be taken when ingesting them.

Disclaimer: Psychedelic drugs offer some of the most power and intense psychological experiences. Additionally these substances are illegal in many places. We understand that even though these substances are illegal, their use occurs frequently. We do not condone breaking of the law. By providing accurate information about these substances, we encourage the user to make responsible decisions and practice harm reduction.

Practice Harm Reduction. Proceed with Caution.

An unusual psychedelic with similar effects to 2C-B and a slightly longer duration, but maligned because of some deaths in the 2000s. Also similar to 2c-t-7, but with a shorter duration. Potentially unsafe with stimulants and empathogens.


It is a member of the 2C-x family of psychedelic phenethylamines, all of which were derived from the systematic modification of the mescaline molecule. 2C-T-2 was first synthesized and tested for activity in humans by Alexander Shulgin in 1981 and described in his 1991 book PiHKAL ("Phenethylamines I Have Known and Loved"). It is a member of the so-called "magical half-dozen" which refers to Shulgin's self-rated most important phenethylamine-derived compounds, all of which except mescaline he developed and synthesized himself.

They are found within the first book of PiHKAL, and are as follows: mescaline, DOM, 2C-B, 2C-E, 2C-T-2 and 2C-T-7. Anecdotal reports generally characterize 2C-T-2 as a highly dose sensitive psychedelic known for its open headspace and unpredictable body load. Very little data exists about the pharmacological properties, metabolism, and toxicity of 2C-T-2, and it has a relatively short history of human usage.

Many reports also indicate that its physical effects may be too severe for those who are not already experienced with psychedelics or suffer from pre-existing physical conditions. It is highly advised to approach this hallucinogenic substance with the proper amount of precaution and harm reduction practices if using it.

Following the initial positive results found by Shulgin’s research group, a more formal study was carried out by psychedelic psychotherapy pioneer Myron J. Stolaroff who was interested in evaluating the potential use of 2C-T-2 in psychotherapy. Based on the experiences of forty participants in the study who took 2C-T-2, Stolaroff compared the effects favorably to MDMA, describing it as more emotionally opening and permitting a wider exploration of feelings and thoughts.




2C-T-2 belongs to the 2C family of phenethylamines which contain methoxy functional groups CH3O- attached to carbons R2 and R5 of the benzene ring.

2C-T-2 is also substituted at R4 with an ethyl thioether group. 2C-T-2 is a close structural analogue of 2C-T-7; the two differ by the length of the alkane chain in their thioether functional group.

Pharmacological Effects

The mechanism of action that produces 2C-T-2’s hallucinogenic and entheogenic effects has not been established in scientific literature; however, its primary psychedelic effects are more than likely a result of its efficacy at the 5-HT2A receptor as a partial agonist. This mechanism of action is shared by many other psychedelic phenethylamines and tryptamines. Athough no established scientific experiments have been performed to establish MAO-A inhibition of 2C-T-2, phenethylamine derivatives substituted with an alkylthio group at the 4 position (4-MTA, and the 2,5-desmethoxy derivative of 2C-T-7) are known to act as selective monoamine oxidase A inhibitors. Furthermore, many compounds of the amphetamine-analogs of the 2C-T-x have been found to have highly selective MAO-A inhibition. Therefore, this substance may likewise have MAOI effects. However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.

Subjective Effects

Disclaimer: The effects listed below are cited from the Subjective Effect Index (SEI), which relies on assorted anecdotal reports and the personal experiences of PsychonautWiki contributors. As a result, they should be taken with a healthy amount of skepticism. It is worth noting that these effects will not necessarily occur in a consistent or reliable manner, although higher doses (common+) are more likely to induce the full spectrum of reported effects. Likewise, adverse effects become much more likely on higher doses and may include serious injury or death.

Physical Effects

Psychological Effects

The head space of 2C-T-2 is described by many as one which is both insightful and relatively normal in its thought processes even at moderate to high doses.

Visual Effects




The visual geometry that is present throughout this experience can be described as somewhat similar in appearance to that of ayahuasca, psilocin, and 4-AcO-DMT with mystical and shamanic undertones which combine with synthetic digital undertones reminiscent of LSD or 2C-E. 2C-T-2's geometry can be comprehensively described through its variations as intricate in complexity, abstract in form, organic but somewhat synthetic in style, structured in organization, brightly lit and multicoloured in scheme, glossy in shading, rounded in edges, large in size, fast in speed, smooth in motion, mostly angular in corners, immersive in-depth and consistent in intensity. The visuals have a contradictory natural and synthetic feel to them which is reminiscent of DOC or 2C-P. Higher doses are more likely to result in states of level 8B visual geometry, but may also lead into level 8A visual geometry (as with 2C-T-7).

Hallucinatory states

At common to high doses, 2C-T-2 is capable of producing a full range of high-level hallucinatory states in a fashion that is more consistent and reproducible than that of many other commonly used psychedelics. This holds particularly true in comparison to other substances within the phenethylamines family. These effects include:

  • Transformations
  • External hallucination (autonomous entities; settings, sceneries, and landscapes; perspective hallucinations and scenarios and plots) - In comparison to other psychedelics such as ayahuasca, 2C-T-2 is very high in external hallucinations. This particular effect commonly contains hallucinations with scenarios, settings, concepts and autonomous entity contact manifested as dense solidified geometric matter or physical objects of imagined concepts. They are more common within dark environments and can be described as external in their manifestation, lucid in believability, interactive in style and almost exclusively of a personal, religious, spiritual, science-fiction, fantasy, surreal, nonsensical or transcendental nature in their overall theme.
  • Internal hallucination (autonomous entities; settings, sceneries, and landscapes; perspective hallucinations and scenarios and plots) - In comparison to other psychedelics such as LSD, 2C-T-2 is very high in hallucinations embedded within visual geometry. This particular effect commonly contains hallucinations with scenarios, settings, concepts and autonomous entity contact. They are more common within dark environments and can be described as internal in their manifestation, lucid in believability, interactive in style and almost exclusively of a personal, religious, spiritual, science-fiction, fantasy, surreal, nonsensical or transcendental nature in their overall theme.
