Summary
1,4-BDO is a prodrug for GHB, metabolized by alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH). Individual metabolic variability means two users can respond very differently to the same dose. Onset is slower than GBL, making redosing particularly risky as people often mistakenly believe the first dose was weak.

“Swiss harm-reduction guidance lists BDO oral low/common/high bands of roughly 0.5-1.0 mL, 1.0-2.5 mL, and 2.5-4.0 mL, with >4 mL commonly producing unrousable sleep; they explicitly advise not to redose for at least 2 hours because delayed stacking is a frequent cause of overdose.” — Swiss harm-reduction guidance via dose.wiki

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. With GHB and GBL, tolerance drops after you stop, so the amount you used to take can cause an overdose, and the gap between the dose you want and an overdose is small and hard to judge.

Effects
Aggregated from 44 single-substance Erowid experience reports; 15 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.

Also reported in combinations. In the 15 1,4-Butanediol reports where another drug was taken too, 5 mention hospital, emergency services or an overdose, 2 a seizure and 0 psychosis (too few reports for percentages). In the 44 single-substance reports: 34.1%, 9.1% and 0.0%. These are not in the figures above: they cannot be put down to 1,4-Butanediol alone, and a mention is not always something that happened to the writer.

Erowid 8 reports 2 neutral 6 cautionary visit
I donΒt normally feel inclined to write on forums, I read them, make a judgment and act. Heck, often I already know what I want to do, but I read the articles for that one out of thousands that conforms to what I want to do and itΒs settled.
After much trial and error, usually accompanied by an overwhelming sensation of riding a psychedelic tilt-a-whirl, like being too drunk, but a bit more lucid (so you can think about how stupid it was to drink a second helping), I have arrived at 5ml of 1,4B stirred into an 8 oz. glass of citrus juice as the right mix.
I heard about 1,4 while searching for a non prescription sleep aid that did not interfere with the natural stages of sleep. Indirectly I found out that 1,4 was used recreationally and a larger percentage of it activates the natural production of GHB in the body.
I wrote this over a year ago and find it as pertinent as ever: ΒIΒve recently posted on various message boards about 1,4 Butanediol and have come to a disappointing conclusion.
1,4-BDO Is Highly Addictive and Can Be Deadly I'm gonna try and keep this short and to the point. I'm writing this because lately there's so many ppl/kids using all of these research chems etc, and I'd like to try and save as many ppl/especially kids from trying this BDO and having it ruin and/or permanently damage the...
After having heard a little on the radio about the new 'legal' form of GHB floating around the market in Australia I did a little research and was surprised at how easy it was to obtain two litres of 1,4 Butanediol for a very reasonable price.
im telling this story to provide anyone who wants to try 1,4b.it is a highly addictive substance not a toy. i started useing this substance over a 1 1/2 yrs ago. i tried it and loved it no nasty beer breath but with all the effects. so i bought a bunch of it. none for sale all for myself.

This is a collection of experiences and overall reflection of the chemical 1,4 BDO. For those who don't want to read through my background info and collection of 1,4 BDO experiences, you can start with the 8th paragraph which is the primary focus of this report.
Fuck that shit! I'd recommend staying away from it. I've been experiencing difficulties with going to sleep and especially sleeping through the whole night for my whole life. So I bought a bottle, took 4.5ml first day - felt good. Slept good. That's what I bought it for.
