2,5-Dimethoxy-4-ethylfluorothiophenethylamine (also known as 2C-T-21, or colloquially as Aurora) is a psychedelic substance of the phenethylamine chemical class that produces psychedelic effects when administered. 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-21 was first synthesized by Alexander Shulgin and documented in his book PiHKAL ("Phenethylamines I Have Known and Loved"). The dosage range is listed as 8–12 mg. It is described in various reports as being generally relaxed and clear-headed with mild visual effects. In his book "Thanatos To Eros, 35 Years of Psychedelic Exploration", Myron Stolaroff describes it as "not psychedelic, but a wonderful energizer", along with displaying a notable lack of appetite suppression typically observed with members of its class.
In March 2004, a 22-year-old American male died after ingesting an unknown amount of 2C-T-21. This death became part of a two-year DEA investigation called "Operation Web Tryp" which ended with the arrests of 10 persons involved in the online distribution of research chemicals. 2C-T-21 remains unscheduled in the United States.
Very little data exists about the pharmacological properties, metabolism, and toxicity of 2C-T-21, and it has little history of human usage. Today, it is used for the purposes of recreation and experimental psychotherapy. It has no history of being sold on the streets and is very sporadically sold online as a grey area research chemical. It is strongly advised to use harm reduction practices if using this substance.

2C-T-21, or 2,5-dimethoxy-4-ethylfluorothiophenethylamine, is a substituted phenethylamine featuring a phenyl ring bound to an amino (NH2) group through an ethyl chain. 2C-T-21 contain methoxy functional groups CH3O- attached to carbons R2 and R5 of the benzene ring as well as an ethylfluoro thioether group attached to carbon R4 of the phenyl ring.
2C-T-21 belongs to the 2C family of phenethylamines, all of which contain methoxy groups on the 2 and 5 positions of the benzene ring.
2C-T-21's psychedelic effects are believed to come from its efficacy at the 5-HT2A receptor as a partial agonist. However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.

The effects listed below are based upon the subjective effects index and personal experiences of PsychonautWiki contributors. The listed effects should be taken with a grain of salt and will rarely (if ever) occur all at once, but heavier doses will increase the chances and are more likely to induce a full range of effects. Likewise, adverse effects become much more likely on higher doses and may include injury or death.
- Stimulation - In terms of its effects on the physical energy levels of the user, 2C-T-21 is generally considered to be energetic and stimulating in a fashion is comparable to that of other phenethylamines such as 2C-B, 2C-E and 2C-P. However, at certain doses and contexts, it may produce periods of notable sedation.
- Spontaneous physical sensations - The "body high" of 2C-T-21 is intense, but in comparison to 2C-E or 2C-B, it can be considered mild though is still capable of becoming very powerful and highly physically euphoric. The sensation itself can be described as intense and will manifest itself in the form of a continuously shifting tingling sensation that travels up and down the body in spontaneous waves.
- Bodily control enhancement
- Changes in felt bodily form
- Tactile enhancement
- Temperature regulation suppression
- Abnormal heartbeat
- Increased blood pressure
- Increased heart rate
- Difficulty urinating or Frequent urination
- Increased perspiration
- Muscle contractions
- Muscle spasms
- Muscle cramps
- Nausea - Mild to extreme nausea is commonly reported when consumed in moderate to high dosages, and either passes once the user has vomited or gradually fades by itself as the peak sets in.
- Stomach bloating
- Stomach cramps
- Teeth grinding
- Excessive yawning
- Pupil dilation
- Watery eyes
- Drifting (melting, flowing, breathing and morphing) - In comparison to other psychedelics, this effect can be described as highly detailed, slow and smooth in motion, static in appearance.
- After images
- Symmetrical texture repetition
- Colour shifting
The head space of 2C-T-21 is described by many as one which is both insightful and relatively normal in its thought processes even at moderate to high dosages.
- Emotion enhancement
- Thought acceleration
- Novelty enhancement
- Time distortion
- Increased music appreciation
- Analysis enhancement - 2C-T-21 is notable for providing an unusual sense of outrospection.
- Personal bias suppression

Toxicity and harm potential
This toxicity and harm potential section is a stub.
As such, it may contain incomplete or even dangerously wrong information. You can help by expanding upon or correcting it.
On March 9, 2004, a 22-year-old American male consumed an unknown dose of 2C-T-21 by sticking his tongue into a vial of powder he had purchased online. He developed a temperature of 108 degrees Fahrenheit (42 degrees Celsius), had a tonic-clonic seizure, and slipped into a coma before dying four days later. Little is known about the toxicity of 2C-T-21 beyond this incident.
It is strongly discouraged to administer 2C-T-21 non-orally because this may cause vomiting, numerous negative side effects, or death at high doses.
Tolerance and addiction potential
2C-T-21 is not habit-forming and the desire to use it can actually decrease with use. It is most often self-regulating.
Tolerance to the effects of 2C-T-21 are built almost immediately after ingestion. After that, it takes about 3 days for the tolerance to be reduced to half and 7 days to be back at baseline (in the absence of further consumption). 2C-T-7 presents cross-tolerance with all psychedelics, meaning that after the consumption of 2C-T-7 all psychedelics will have a reduced effect.
Although many psychoactive substances are safe on their own, they can become dangerous and even life-threatening when combined with other substances. The list below contains some common potentially dangerous combinations, but may not include all of them. Certain combinations may be safe in low doses of each but still increase the potential risk of death. Independent research should always be done to ensure that a combination of two or more substances is safe before consumption.
If 2C-T-21 does have MAOI effects as commonly speculated, this could indicate that 2C-T-21 is more likely to induce serotonin syndrome or general neurotransmitter overload (especially at high dosages) than other serotonergic psychedelics. This may make it dangerous to combine it with other MAOIs, stimulants and certain substances which releases neurotransmitters such as serotonin or dopamine. These substances include but are not limited to:

- Canada - As of October 31st, 2016; 2C-T-21 is a controlled substance (Schedule III) in Canada. 
- United Kingdom - 2C-T-21 is a Class A drug in the United Kingdom as a result of the phenethylamine catch-all clause.
- United States - 2C-T-21 is technically not scheduled in the United States, but could be considered an analogue of 2C-T or 2C-T-7 and may therefore be considered a Schedule I drug under the Federal Analogue Act.
