2,5-Dimethoxy-4-iodophenethylamine (commonly known as 2C-I) 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.[1]

2C-I was first synthesized and investigated for human activity by Alexander Shulgin in 1976[2] and later described in his 1991 book PiHKAL ("Phenethylamines I Have Known and Loved"). Its PiHKAL entry notes it for being "very colorful and active" but without "feelings of insight, revelation, or progress toward the true meaning of the universe."[3]

This substance is typically used recreationally for its psychedelic as well as moderate stimulating and entactogenic effects. It has been explored as a potential stimulant nootropic in the 1-8mg dosage range.[Controversial]

2C-I is sometimes confused for the analog 25I-NBOMe (an abbreviated form of 2C-I-NBOMe). It is commonly sold in its hydrochloride salt form, which is a fluffy, sparkling, white powder that is sometimes pressed into tablets for distribution on the street. It first briefly gained some popularity in the late 1990s and early 2000s, where it was sold in several smart shops as a replacement for 2C-B following its scheduling in 1995.[4] It also has a history of being sold online as a research chemical before becoming scheduled.

Limited data exists about the pharmacological properties, metabolism, and toxicity of 2C-I, and it has a limited history of human use. It is highly advised to use harm reduction practices if using this substance.

Chemistry

Generic structure of a phenethylamine molecule

2C-I, or 2,5-dimethoxy-4-iodophenethylamine, is a substituted phenethylamine comprising a phenyl ring bound to an amino (NH2) group through an ethyl chain. 2C-I contains methoxy functional groups CH3O- attached to carbons R2 and R5 as well as an iodine atom attached to carbon R4 of the phenyl ring. 2C-I belongs to the 2C family of phenethylamines which contain methoxy groups on the 2 and 5 positions of the benzene ring.[5]

Pharmacology

Further information: Serotonergic psychedelic

2C-I'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 remains the subject of ongoing scientific investigation.

Subjective effects

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 serious injury or death.

Toxicity and harm potential

The toxicity and long-term health effects of recreational 2C-I use do not seem to have been studied in any scientific context and the exact toxic dose is unknown. This is because 2C-I is a research chemical with very little history of human usage.

Anecdotal reports from those who have tried 2C-I suggests that there are no negative health effects attributed to simply trying the substance by itself at low to moderate doses and using it very sparingly (but nothing can be completely guaranteed). Independent research should always be done to ensure that a combination of two or more substances is safe before consumption.

It is strongly recommended that one use harm reduction practices, such as volumetric dosing, when using this substance so as to ensure the accurate administration of the intended dose.

Tolerance and addiction potential

Although no formal studies have been conducted, it is not unreasonable to assume that as is the case with psychedelics in general, 2C-I is not habit-forming and that the desire to use it can actually decrease with use.

Tolerance to the effects of 2C-I are built almost immediately after ingestion. After that, it takes about 3-5 days for the tolerance to be reduced to half and 7-10 days to be back at baseline (in the absence of further consumption). 2C-I presents cross-tolerance with all psychedelics, meaning that after the consumption of 2C-I all psychedelics will have a reduced effect.

Dangerous interactions

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.
