Before my experience with Clonazolam, I had enjoyed several types of Benzodiazepines such as Xanax, Klonopin, and Valium on many occasions. I first heard of RC benzos on an internet drug forum, and saw that they were cheap, legal, and readily available! What could go wrong? It'll be fun! I ordered 2 vials of 50mL Clona...

Summary
Clonazolam (also known as Clonitrazolam) is a novel depressant substance of the benzodiazepine chemical class which produces anxiolytic, sedative, muscle relaxant, and amnesic effects when administered. This compound is a novel research chemical derivative of the FDA-approved drugs clonazepam (Klonopin, Rivitrol) and alprazolam (Xanax). Clonazolam is reported to be roughly 2.5x as potent as alprazolam.

Build-up
develops over 1–4 weeks of daily use; hypnotic tolerance faster than anxiolytic tolerance
Reset
Falls after you stop, at a rate that varies from person to person. If you've been using regularly, cut down gradually with medical help rather than stopping suddenly.
No tolerance chart. Our decay curves for these drugs were estimates, and a curve can make tolerance look longer-lasting than it is, which is the dangerous direction.
How fast tolerance to these drugs fades after a break has not been measured well enough to draw, so don't count on a dose you used to take still being safe: after time off, start with a much smaller amount and don't use alone. Mixing sedatives with each other, with alcohol or with opioids sharply raises the risk of a fatal overdose. If you've been using regularly, don't stop suddenly: withdrawal from benzodiazepines, alcohol or GHB/GBL can cause seizures or delirium, so get medical help to cut down gradually.

Effects
Aggregated from 16 single-substance Erowid experience reports; 12 Erowid reports where another drug was taken too are left out
Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect or something witnessed can count). Mentions saying the effect did not happen are left out; that check reads keywords, so it can miss some. The shaded band on a bar, and the small range after its number, is the 95% interval: where the share could plausibly be with other reports of the same kind. Fewer reports, wider band. Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.
Too few reports for bars: these effects come from 16 single-substance Erowid reports, and a bar is drawn only from 20 reports or more. With fewer, a percentage cannot tell a common effect from a rare one. Counts are shown instead. Why 20?

Also reported in combinations. In the 12 Clonazolam reports where another drug was taken too, 2 mention hospital, emergency services or an overdose, 0 a seizure and 1 psychosis (too few reports for percentages). In the 16 single-substance reports: 4, 2 and 0. These are not in the figures above: they cannot be put down to Clonazolam alone, and a mention is not always something that happened to the writer.

It is very rare for me to write off a substance entirely. I think most drugs can be used successfully (or at least harmlessly) when the right information and resources are available. However, I must recommend that you entirely clear of clonazolam.
I'll try keep it short and simple, but go into detail where I feel may be beneficial as possible for people reading for harm reduction and research. I'm in good health, drink once or twice a week (beer or glass of wine after work, which is 9-5 Mon-Fri) and never get slaughtered on alcohol.
I bought some clonazolam with the intention of taking it recreationally. Before this I've had experience with prescription benzodiazepines such as Xanax and also research chemicals such as the very potent flubromazolam. I read up on the web about this new benzo named clonazolam.
I decided to take some Clonazolam on a Sunday night to help me go to bed and relax after a long day - I started with 1mg sublingually and move up in my dose over time. I remember quite fondly that I took 3mg more sublingually and 1mg insufflated with nasal spray.
I'll start this off with an experience report I wrote right after my first time taking this substance, in which I suffered the negative consequences of this drug. The first time I only took a measly 0.5mg of this substance! Afterwards, I'll talk about my SECOND negative experience.
I'm writing this as a warning to anyone that might think they can eyeball an appropriate dose of Clonazolam powder. It's EXTREMELY dangerous to ingest raw powder of ANY drug, let alone one that is active in the microgram range. I am lucky to have survived (not an exaggeration).
Multiple Seizures Near Death By the age of twenty I was an experienced drug user, specializing in benzo use. People in the past noticed my high affinity for pills. Naturally, when my friend at the time who was a neuroscience major told me he got a pill that works STRONG for 8 to 12 hours I was interested.
