Q: Does Benzodiazepines cause compulsive redosing?

Yes. Compulsive redosing is a documented cognitive effect of Benzodiazepines. An overwhelming, difficult-to-resist urge to continuously take more of a substance in order to maintain or intensify its effects, often overriding rational judgment and self-control.

Substances causing compulsive redosing

Benzodiazepines is known to produce compulsive redosing, a cognitive effect. An overwhelming, difficult-to-resist urge to continuously take more of a substance in order to maintain or intensify its effects, often overriding rational judgment and self-control.

About Compulsive redosing

Compulsive redosing is the experience of a powerful and difficult-to-resist urge to continuously redose a psychoactive substance in an effort to increase or maintain the subjective effects it produces. This drive can feel almost automatic, as though the decision to take more has already been made before the person consciously deliberates. The desire often intensifies as the peak effects begin to wane, creating a cycle in which the user chases an increasingly elusive high.

This effect is often accompanied by and driven by other coinciding experiences such as cognitive euphoria, physical euphoria, anxiety suppression, disinhibition, motivation enhancement, and ego inflation. These accompanying effects work together to cloud judgment and reduce the person's ability to critically evaluate whether redosing is wise or safe. The combination of pleasurable reinforcement and impaired decision-making creates a feedback loop that can be extremely difficult to break without external intervention.

The intensity of compulsive redosing varies significantly depending on the substance, route of administration, and individual susceptibility. Substances that produce rapid-onset, short-duration euphoria tend to induce the most severe compulsive redosing. Vaporized or injected stimulants, for example, produce an intense but brief rush that rapidly gives way to a craving for more. Substances like MDPV and alpha-PVP are notorious for producing compulsive redosing so powerful that users may continue taking the substance even when the negative side effects clearly outweigh any remaining positive ones.

Methamphetamine, cocaine, and various cathinone derivatives are among the most commonly associated substances. When methamphetamine is vaporized or injected, the overwhelming euphoric rush upon initial administration frequently triggers compulsive redosing behavior that can continue for days. Cocaine's short duration of action similarly encourages rapid, repeated dosing. Many research chemicals in the cathinone and pyrovalerone families share this property to varying degrees, and some users report that certain substances make the urge feel nearly impossible to resist.

Compulsive redosing is considerably more likely to manifest when the user has a large supply of the substance readily accessible. Harm reduction strategies include pre-weighing intended dosages before beginning a session, removing the remaining supply from sight or reach, giving the substance to a trusted friend for safekeeping, and setting firm rules about maximum dosages and redosing intervals beforehand. Even with these precautions, the pull of this effect can be strong enough to override planned limits, making it one of the more dangerous behavioral patterns associated with substance use.

The risk of compulsive redosing is a significant contributor to acute toxicity events, as users may consume far more of a substance than originally intended. This is particularly dangerous with substances that have a narrow margin between recreational and dangerous doses, or with substances whose full effects take time to manifest, leading the user to redose before realizing they have already taken too much.

How Benzodiazepines Produces This Effect

Pharmacodynamics

Benzodiazepines work by increasing the effectiveness of the endogenous chemical, GABA, to decrease the excitability of neurons. This reduces the communication between neurons and, therefore, has a calming effect on many of the functions of the brain.

GABA controls the excitability of neurons by binding to the GABAA receptor. The GABAA receptor is a protein complex located in the synapses between neurons. All GABAA receptors contain an ion channel that conducts chloride ions across neuronal cell membranes and two binding sites for the neurotransmitter gamma-aminobutyric acid (GABA), while a subset of GABAA receptor complexes also contain a single binding site for benzodiazepines. Binding of benzodiazepines to this receptor complex does not alter binding of GABA. Unlike other positive allosteric modulators that increase ligand binding, benzodiazepine binding acts as a positive allosteric modulator by increasing the total conduction of chloride ions across the neuronal cell membrane when GABA is already bound to its receptor. This increased chloride ion influx hyperpolarizes the neuron's membrane potential. As a result, the difference between resting potential and threshold potential is increased, and firing is less likely. Different GABAA receptor subtypes have varying distributions within different regions of the brain and, therefore, control distinct neuronal circuits. Hence, activation of different GABAA receptor subtypes by benzodiazepines may result in distinct pharmacological actions. In terms of the mechanism of action of benzodiazepines, their similarities are too great to separate them into individual categories such as anxiolytic or hypnotic. For example, a hypnotic administered in low doses produces anxiety-relieving effects, whereas a benzodiazepine marketed as an anti-anxiety drug at higher doses induces sleep.

The subset of GABAA receptors that also bind benzodiazepines are referred to as benzodiazepine receptors (BzR). The GABAA receptor is a heteromer composed of five subunits, the most common ones being two αs, two βs, and one γ (α2β2γ1). For each subunit, many subtypes exist (α1–6, β1–3, and γ1–3). GABAA receptors that are made up of different combinations of subunit subtypes have different properties, different distributions in the brain, and different activities relative to pharmacological and clinical effects. Benzodiazepines bind at the interface of the α and γ subunits on the GABAA receptor. Binding also requires that alpha subunits contain a histidine amino acid residue, (i.e., α1, α2, α3, and α5 containing GABAA receptors). For this reason, benzodiazepines show no affinity for GABAA receptors containing α4 and α6 subunits with an arginine instead of a histidine residue. Once bound to the benzodiazepine receptor, the benzodiazepine ligand locks the benzodiazepine receptor into a conformation in which it has a greater affinity for the GABA neurotransmitter. This increases the frequency of the opening of the associated chloride ion channel and hyperpolarizes the membrane of the associated neuron. The inhibitory effect of the available GABA is potentiated, leading to sedative and anxiolytic effects. For instance, those ligands with high activity at the α1 are associated with stronger hypnotic effects, whereas those with higher affinity for GABAA receptors containing α2 and/or α3 subunits have good anti-anxiety activity.

GABAA receptors participate in the regulation of synaptic pruning by prompting microglial spine engulfment. Benzodiazepines have been shown to upregulate microglial spine engulfment and prompt overzealous eradication of synaptic connections. This mechanism may help explain the increased risk of dementia associated with long-term benzodiazepine treatment.

The benzodiazepine class of drugs also interacts with peripheral benzodiazepine receptors. Peripheral benzodiazepine receptors are present in peripheral nervous system tissues, glial cells, and to a lesser extent the central nervous system. These peripheral receptors are not structurally related or coupled to GABAA receptors. They modulate the immune system and are involved in the body's response to injury. Benzodiazepines also function as weak adenosine reuptake inhibitors. It has been suggested that some of their anticonvulsant, anxiolytic, and muscle relaxant effects may be in part mediated by this action. Benzodiazepines have binding sites in the periphery, however their effects on muscle tone is not mediated through these peripheral receptors. The peripheral binding sites for benzodiazepines are present in immune cells and the gastrointestinal tract.

Pharmacokinetics

A benzodiazepine can be placed into one of three groups by its elimination half-life, or the time it takes for the body to eliminate half of the dose. Some benzodiazepines have long-acting active metabolites, such as diazepam and chlordiazepoxide, which are metabolised into desmethyldiazepam. Desmethyldiazepam has a half-life of 36–200 hours, and flurazepam, with the main active metabolite of desalkylflurazepam, with a half-life of 40–250 hours. These long-acting metabolites are partial agonists.

Short-acting compounds have a median half-life of 1–12 hours. They have few residual effects if taken before bedtime, rebound insomnia may occur upon discontinuation, and they might cause daytime withdrawal symptoms such as next day rebound anxiety with prolonged usage. Examples are brotizolam, midazolam, and triazolam.
Intermediate-acting compounds have a median half-life of 12–40 hours. They may have some residual effects in the first half of the day if used as a hypnotic. Rebound insomnia, however, is more common upon discontinuation of intermediate-acting benzodiazepines than longer-acting benzodiazepines. Examples are alprazolam, estazolam, flunitrazepam, clonazepam, lormetazepam, lorazepam, nitrazepam, and temazepam.
Long-acting compounds have a half-life of 40–250 hours. They have a risk of accumulation in the elderly and in individuals with severely impaired liver function, but they have a reduced severity of rebound effects and withdrawal. Examples are diazepam, clorazepate, chlordiazepoxide, and flurazepam.

Benzodiazepines can be administered via Oral (Diazepam equiv.). The route of administration can influence both the onset and intensity of compulsive redosing.
