Chlordiazepoxide (also known as Librium) is a depressant substance of the benzodiazepine class. Its mechanism of action is to increase the effects of the inhibitory neurotransmitterGABA.
Chlordiazepoxide is notable among benzodiazepines for having a relatively long duration of action, compounded by the even longer half-life of its active metabolites, primarily nordiazepam (up to 300 hours). It is indicated for the short-term treatment of debilitating anxiety and alcohol withdrawal. Compared to other benzodiazepines, chlordiazepoxide is not particularly potent and has a long onset. Hence, it is seldom used as a PRN anxiolytic (given its prolonged onset) or for its other indications (given its low efficacy compared to other benzodiazepines).
Subjective effects include anxiety suppression, sedation, and muscle relaxation.[2] Its usage is rare, and limited mostly to managing symptoms of alcohol withdrawal. Given its particularly strong hypnotic and amnesic effects, infrequent prescription, and prolonged onset, it is not commonly used recreationally.
Chlordiazepoxide is considered to have low toxicity.[citation needed] It has moderate abuse potential, given its long duration of action. Recreational use is uncommon, as it is not often prescribed outside the context of detoxification and withdrawal management. It still however produces physical and psychological symptoms of dependence with extended use. Additionally, it can contribute to death by respiratory depression if combined with alcohol, opiates, and other depressants. It is highly advised to use harm reduction practices if using this substance.
It should be noted that the sudden discontinuation of benzodiazepines can be potentially dangerous or life-threatening for individuals using regularly for extended periods of time, sometimes resulting in seizures or death.[3] It is highly recommended to taper one's dose by gradually lowering the amount taken each day for a prolonged period of time instead of stopping abruptly.[4]

Chlordiazepoxide was accidentally discovered in 1957. and was found to have sedative and hypnotic effects. This discovery led to its marketing in 1960 and the development of the benzodiazepine class of drugs. Six years later, in 1963, diazepam (which is much more widely used than chlordiazepoxide), was created, kicking off a cascade of benzodiazepines. Initially met with widespread approval due to their efficacy, benzodiazepines were later restricted in light of evidence of their potential for recreational usage and liability to cause dependence and addiction.[5]
Chlordiazepoxide is a prodrug to Nordiazepam which functions as a partial agonist at ω1 and ω2 Benzodiazepine Receptors which is an allosteric site of the GABAa receptor. The conformational change as a result of van der waals Forces allows for roughly a 300% increase in GABAa receptor activation. Nordiazepam is a metabolite of many Benzodiazepines which is slowly metabolized to Oxazepam (full agonist activity) and subsequently conjugated.
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 PsychonautWikicontributors. 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 euphoria - This effect is often only present in individuals who are naturally anxious, and, when it presents itself, is tame in comparison to more commonly used euphoriants.
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%).[6][7]
These paradoxical effects occur with greater frequency in recreational abusers, individuals with mental disorders, children, and patients on high-dosage regimes.[8][9]
Cognitive effects
The most prominent of these cognitive effects generally include:
Delusions of sobriety - This is the false belief that one is perfectly sober despite obvious evidence to the contrary such as severe cognitive impairment and an inability to fully communicate with others. It most commonly occurs at heavy dosages.
Emotion suppression - Although this compound primarily suppresses anxiety, it also dulls other emotions in a manner which is distinct but less intensive than with that of antipsychotics.
Language suppression - Chlordiazepoxide & most benzodiazepines are known to cause slurred speech and difficulty communicating words in a clear fashion.
After effects
Rebound anxiety - Rebound anxiety is a commonly observed effect with anxiety relieving substances like benzodiazepines. It typically corresponds to the total duration spent under the substance's influence along with the total amount consumed in a given period, an effect which can easily lend itself to cycles of dependence and addiction.
Residual sleepiness - While benzodiazepines can be used as an effective sleep-inducing aid, their effects may persist into the morning afterward, which may lead users to feeling "groggy" or "dull" for up to a few hours.

Chlordiazepoxide has a low toxicity relative to dose.[2] However, it is [[Toxicity::potentially lethal when mixed with depressants like alcohol or opioids]].
It is strongly recommended that one use harm reduction practices, such as volumetric dosing, when using this substance to ensure the administration of the intended dose.
Lethal dosage
Chlordiazepoxide has a high LD50. Alone, fatal benzodiazepine overdoses occur only with extraordinarily high dosages, but when combined with other depressants, this threshold is lowered significantly.
Tolerance and addiction potential
Like other benzodiazepines, chlordiazepoxide is liable to cause physical dependence and addiction in a manner directly correlated to how long the substance is used for and the dosage at which the substance is used. Long-term treatment with benzodiazepines is not suggested, as it often results in a physical dependence that presents uncomfortable, if not life-threatening, withdrawal symptoms.
Warning:Many psychoactive substances that are reasonably safe to use on their own can suddenly become dangerous and even life-threatening when combined with certain other substances. The following list provides some known dangerous interactions (although it is not guaranteed to include all of them).
Always conduct independent research (e.g. Google, DuckDuckGo, PubMed) to ensure that a combination of two or more substances is safe to consume. Some of the listed interactions have been sourced from TripSit.
Dissociatives - 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.
Stimulants - 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. If combined, one should strictly limit themselves to only dosing a certain amount of benzodiazepines per hour. This combination can also potentially result in severe dehydration if hydration is not monitored.

Internationally, chlordiazepoxide is a Schedule IV controlled drug under the Convention on Psychotropic Substances.[12] Chlordiazepoxide is regulated in most countries as a prescription drug.
