Diclazepam
Aliases: Chlorodiazepam, 2'-chloro-diazepam
Summary
Diclazepam is an unscheduled research chemical benzodiazepine not approved for medical use in most countries. It is structurally related to diazepam but approximately 10 times more potent in animal studies. Its long half-life of approximately 42 hours and active metabolites (delorazepam, lorazepam, lormetazepam) lead to accumulation with repeated use and prolonged effects lasting days.

Tolerance
Tolerance Decay
Benzodiazepine tolerance to hypnotic/sedative effects can develop within days to weeks of regular use and decays slowly over weeks after cessation; cross-tolerance exists across benzodiazepines and is partial with Z‑drugs. Values are heuristic for planning safer spacing between uses; strong inter-individual variability. Data quality: mixed guidance from public-health profiles and community experience rather than controlled trials.
