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
Build-up
develops over 1β4 weeks of daily use; hypnotic tolerance faster than anxiolytic tolerance
Reset
weeks to months depending on half-life and duration of use; taper recommended
Tolerance Decay
Full tolerance

Acute tolerance: develops within a single session β the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
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 Zβdrugs. 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.

With the explosion of 'research chemical' benzos and benzo derivatives/analogues, I've had the opportunity to try a few (namely: etizolam, clonazolam, nifoxipam, and diclazepam) on many occasions.
I took a range of other drugs while under the influence of this drug. I remember taking: 7 gram of base (form of amphetamine in my country) Lots of weed Unsure how much alcohol, about a quarter of a litre of vodka 30mg of Amitriptyline Possibly more, memory was affected I order 50 of these small tablets (1mg each) from...
Steady Hands in the Land of Diclazepam Brief background on my use without sounding snoody: done most recreational pharms particularly stimulants benzos and opiates, am currently prescribed suboxone and have tried and tripped on most common substances and several uncommon ones.
I have had the experience of wanting a particular substance for an event or experience - MDMA for Bonnaroo, maybe, or a joint after a long hike - only to find that somebody forgot to pack a lighter, didn't bring the shrooms, or whatever - and the drugs never made it to their intended destination.
Quick background: Not on any meds, mentally in a good place, exercise semi-regularly, have a pretty terrible diet. Plenty of drug experience, both ΒtraditionalΒ drugs and many RCs. IΒve read countless reports of diclazepam being Βutter shitΒ and Βalmost entirely benignΒ.
Diclazepam 2mg tablets were purchased from a RC vendor, Β£7.50 for x10 2mg tables. They're very small, almost identical in size to 2mg Roche Diazepam. The colour is a blue/mauve mix. Not unlike those old pimento candies. I originally asked my GP for help with coming off codeine.
Diclazepam. I got 120mg of it because I've been using etizolam to combat General anxiety disorder probably brought on by years of last drinking. I don't drink anymore. Etizolam seemed a miracle cure, and is still my favorite RC benzo for effects. It has alot good to be said about it.
