2,5-Dimethoxy-4-iodoamphetamine (DOI) is a psychedelic drug and a substituted amphetamine. Unlike other substituted amphetamines, however, it is not a stimulant.[2] DOI has a stereocenter and R-(−)-DOI is the more active stereoisomer. In neuroscience research, [125I]-R-(−)-DOI is used as a radioligand and indicator of the presence of 5-HT2A serotonin receptors. DOI's effects have been compared to LSD, although there are differences that experienced users can distinguish. Besides the longer duration, the trip tends to be more energetic than an LSD trip, with more body load and a different subjective visual experience. The after effects include residual stimulation and difficulty sleeping, which, depending on the dose, may persist for days.[2] It is sometimes sold as a substitute for LSD, or even sold falsely as LSD, which may be dangerous because DOI does not have the same established safety profile as LSD.[3]

Research
Research[4] suggests that administration of (R)-DOI blocks pulmonary inflammation, mucus hyper-production, airway hyper-responsiveness and turns off key genes in in-lung immune response. These effects block the development of allergic asthma in a mouse model.

DOI is a 5-HT2A, 5-HT2B and 5-HT2C receptor agonist.[6]
DOI has been shown to be an extremely potent inhibitor of tumour necrosis factor-alpha inflammation at picomolar concentrations in cell studies. TNF-alpha is an important target for research into degenerative conditions such as rheumatoid arthritis and Alzheimer's disease, where the disease process involves tissue damage through chronic inflammation. This could make DOI and other 5-HT2A agonists an entirely new area for development of novel treatments for these conditions.[7]
DOI has also been shown to induce rapid growth and reorganization of dendritic spines and synaptic connections with other neurons, processes known to underlie neuroplasticity.[8]
History
DOI was first synthesized by Alexander Shulgin.[2] The radioactive iodine-125 form of DOI for PET imaging was first developed in the lab of David E. Nichols.
In January 2007, British Police reported that 3 young men had fallen ill, reportedly, after taking DOI at a rave in Biggleswade, near Milton Keynes, and warned others who had taken it to seek medical attention. This would appear to be the first indication that DOI has found more widespread use as a recreational drug in the UK.[9]
An extremely large increase of the hallucinogenic drug has been seen in sales in Adelaide, Australia. It is commonly sold as LSD or just "trips".[10]
Legal Status
Australia
The Standard for the Uniform Scheduling of Medicines and Poisons (SUSMP) of Australia does not list DOI as a prohibited substance.[11]
Canada
Listed as a Schedule 1[12] as it is an analogue of amphetamine.[13] The CDSA was updated as a result of the Safe Streets Act changing amphetamines from Schedule 3 to Schedule 1.[14]
Denmark
Illegal since 8 April 2007.[15]
Sweden
Sveriges riksdag added DOI to schedule I ("substances, plant materials and fungi which normally do not have medical use") as narcotics in Sweden as of August 30, 2007, published by Medical Products Agency in their regulation LVFS 2007:10 listed as DOI, 4-jod-2,5-dimetoxi-amfetamin.[16]
United States
DOI is not scheduled in the United States,[17] but it is likely that DOI would be considered an analog (of DOB), in which case, sales or possession could be prosecuted under the Federal Analogue Act. DOI is regularly used in animal and in vitro research.[citation needed] Scheduling DOI could cause problems for medical researchers.[citation needed]
US State of Florida
DOI is a Schedule I controlled substance in the state of Florida.[18]
