This combination can result in an increased risk of vomiting during unconsciousness and death from the resulting suffocation. If this occurs, users should attempt to fall asleep in the recovery position or have a friend move them into it.
It is dangerous to combine benzodiazepines with stimulants due to the risk of excessive intoxication. Stimulants decrease the sedative effect of benzodiazepines, which is the main factor most people consider when determining their level of intoxication. Once the stimulant wears off, the effects of benzodiazepines will be significantly increased, leading to intensified disinhibition as well as other effects.

History & Culture
Deschloroetizolam is a designer thienotriazolodiazepine that emerged as a novel psychoactive substance in 2014. The compound is structurally derived from etizolam, differing only by the removal of a chlorine atom from the parent molecule—hence the "deschloro" prefix in its name. This minor structural modification results in a substance approximately half as potent as etizolam but with a duration roughly twice as long. The substance first appeared on grey market research chemical vendor websites, marketed primarily to collectors and researchers seeking legal alternatives to controlled benzodiazepines and thienodiazepines. It is sometimes sold under the alternative name "Etizolam-2." Unlike its parent compound etizolam, which holds medical approval in certain countries including Japan, Italy, and India, deschloroetizolam has never been developed for therapeutic use and lacks formal pharmaceutical recognition in any jurisdiction.
Subjective Effect Notes
physical: The physical effects of deschloroetizolam can be broken down into several components which progressively intensify proportional to dosage.
cognitive: The cognitive effects of deschloroetizolam can be broken down into several components which progressively intensify proportional to dosage. The general head space of deschloroetizolam is described by many as one of intense sedation and decreased inhibition. It contains a large number of typical depressant cognitive effects. Paradoxical reactions to benzodiazepines such as increased seizures (in epileptics), aggression, increased anxiety, violent behavior, loss of impulse control, irritability and suicidal behavior sometimes occur (although they are rare in the general population, with an incidence rate below 1%). These paradoxical effects occur with greater frequency in recreational abusers, individuals with mental disorders, children, and patients on high-dosage regimes.

Tolerance to sedation/anxiolysis builds within days of regular use and decays slowly over weeks; figures are heuristic and derived from benzodiazepine class data and community experience rather than DCE-specific trials.

Legal Status
| Country | Status | Notes |
|---|---|---|
| Canada | Not scheduled | Thienodiazepines are not scheduled under Canadian controlled substances legislation. However, sale or provision for human consumption is prohibited as deschloroetizolam lacks approval as a medical drug. |
| Germany | NpSG controlled | Controlled under the Neue-psychoaktive-Stoffe-Gesetz (New Psychoactive Substances Act) since July 18, 2019. Production and import with intent to market, administration to others, and trading constitute criminal offenses. Possession is prohibited but not subject to criminal penalty. |
| Russia | Schedule III | Listed as a Schedule III controlled substance since 2017 under Russian drug control legislation. |
| Switzerland | Verzeichnis E | Specifically named as a controlled substance under Verzeichnis E of Swiss narcotics scheduling. |
| Turkey | Illegal | Classified as a controlled drug under Turkish law. Possession, production, supply, and import are all prohibited activities. |
| United Kingdom | Psychoactive Substances Act | Controlled under the Psychoactive Substances Act 2016, effective May 26, 2016. Production, supply, and import are criminal offenses. Personal possession is not criminalized under this legislation, though the substance remains in a legal grey area. |
Harm Reduction
drugs.wikiDeschloroetizolam is a thienotriazolodiazepine closely related to etizolam; drug checking programs describe it as roughly half as strong per milligram and lasting up to about twice as long as etizolam, which increases next-day impairment risk; plan activities accordingly. Community and HR sources consistently flag benzodiazepines combined with alcohol, opioids, or GHB/GBL as dangerous due to additive/synergistic respiratory depression; avoid these combinations entirely and place any unresponsive person in the recovery position while seeking emergency help. Tramadol with benzodiazepines is particularly risky because it adds respiratory/CNS depression and has seizure potential; avoid this pairing. Etizolam (the parent compound) is primarily metabolized by CYP3A4; given close structural similarity, deschloroetizolam may be similarly affected—CYP3A4 inhibitors (azole antifungals, macrolides, grapefruit) can raise levels and prolong effects; dose conservatively and avoid redosing if such inhibitors are on board. Potency is in the low-milligram range; use a calibrated 0.001 g scale or volumetric dosing and ensure complete dissolution—do not rely on cloudy suspensions as uneven distribution can cause accidental overdoses and blackouts. Illicit supply variability is high; drug checking services have repeatedly detected deschloroetizolam—sometimes unexpectedly—in fentanyl samples; if any opioid exposure is possible, keep naloxone available (it reverses opioids, not benzodiazepines) and avoid using alone. Regular use builds tolerance quickly and can produce significant dependence; abrupt cessation after sustained use can trigger severe withdrawal and seizures—seek medical supervision for any taper. Flumazenil can reverse benzodiazepine effects in medical settings but may precipitate seizures in benzodiazepine-dependent people or mixed overdoses; it must not be self-administered. Avoid driving or operating machinery for at least a full waking day after significant doses due to amnesia, impaired coordination, and residual sedation. Because formal human pharmacokinetic data are limited, all timelines should be treated as approximate; start low, wait full onset and peak, and avoid stacking doses.
