Etodesnitazene (Desnitroetonitazene, Etazen, Etazene, Etazone) is a benzimidazole derived opioid analgesic drug, which was originally developed in the late 1950s alongside etonitazene and a range of related derivatives.[1] It is many times less potent than etonitazene itself, but still 70x more potent than morphine in animal studies. Corresponding analogues where the N,N-diethyl group is replaced by piperidine or pyrrolidine rings also retain significant activity (10x and 20x morphine respectively).[2]
History and culture
Very little is known about etazene's origin, it first came to the public eye in 2020, when it was first seized by law enforcement. People speculate it is a etonitazene like Research chemical, with similar effects but a much lower LD50.
Etazene is an analgesic drug, first reported in 2020, that has been shown to have approximately one thousand to one thousand five hundred times the potency of morphine in animal models, but only sixty to seventy times the potency in humans.
Because it is characterized by a strong dependency potential and a tendency to produce profound respiratory depression, it is not used in humans. It is, however, useful in animal models for addiction studies, particularly those requiring the animals to drink or ingest the agent, because it is not as bitter as opiate salts like morphine sulfate.
Pharmacology
Opioids exert their effects by binding to and activating the μ-opioid receptor. This occurs because opioids structurally mimic endogenous endorphins which are naturally found within the body and also work upon the μ-opioid receptor set. The way in which opioids structurally mimic these natural endorphins results in their euphoria, pain relief and anxiolytic effects. This is because endorphins are responsible for reducing pain, causing sleepiness, and feelings of pleasure. They can be released in response to pain, strenuous exercise, orgasm, or general excitement.
Chemistry
Etazene is a synthetic opioid in the benzimidazole family. The structures of opioids share many similarities. Whereas opioids like hydrocodone, oxycodone, and hydromorphone are synthesized by simple modifications of morphine, etazene and its relatives are synthesized using the benzimidazole chemical structure.
Subjective effects
Disclaimer: The effects listed below cite the Subjective Effect Index (SEI), an open research literature based on anecdotal user reports and the personal analyses of PsychonautWiki contributors. As a result, they should be viewed with a healthy degree of skepticism.
It is also worth noting that these effects will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of effects. Likewise, adverse effects become increasingly likely with higher doses and may include addiction, severe injury, or death ☠.
Physical effects 
-
The general sensation of methadone can be described as one of euphoria, relaxation, anxiety suppression and pain relief.
- Pain relief
- Physical euphoria - This particular substance can be considered as less intense in its physical euphoria when compared with that of morphine or diacetylmorphine (heroin), but stronger than that of other synthetic opioids such as tramadol. The sensation itself can be described as extreme feelings of intense physical comfort, warmth, love and bliss.
- Itchiness
- Respiratory depression - At low to moderate doses, this effect results in the sensation that the breath is slowed down mildly to moderately, but does not cause noticeable impairment. At high doses and overdoses, opioid-induced respiratory depression can result in a shortness of breath, abnormal breathing patterns, semi-consciousness, or unconsciousness. Severe overdoses can result in a coma or death without immediate medical attention.
- Constipation
- Cough suppression
- Difficulty urinating
- Nausea
- Sedation
- Pupil constriction
- Decreased libido
- Appetite suppression
- Orgasm suppression

Toxicity and harm potential

The short-term non-chronic use of opioids is not associated with any physical or neurological toxicity.[citation needed]
Long term effects
The long-term use of opioids causes hormonal imbalance in both men and women.
This negative change in endocrine function in males can lead to: reduced libido, erectile dysfunction, fatigue, depression, reduced facial and body hair, decreased muscle mass, and weight gain.
It is strongly recommended that one use harm reduction practices when using this class of substances.
Dependence and tolerance potential
As with other opioids, the chronic use of etazene can be considered highly addictive with a high potential for abuse and is capable of causing psychological dependence among certain users. When addiction has developed, cravings and withdrawal symptoms may occur if a person suddenly stops their usage.
Tolerance to many of the effects of Etazene develops with prolonged and repeated use. The rate at which this occurs develops at different rates for different effects, with tolerance to the constipation-inducing effects developing particularly slowly for instance. This results in users having to administer increasingly large doses to achieve the same effects. After that, it takes about 3 - 7 days for the tolerance to be reduced to half and 1 - 2 weeks to be back at baseline (in the absence of further consumption). Etazene presents cross-tolerance with all other opioids, meaning that after the consumption of Etazene all opioids will have a reduced effect.
