The first time I heard anything at all about the medicine Halcion was while reading the Mötley Crüe / Nikki Sixx books, 'The Dirt', and 'The Heroin Diaries'. The infamously debauched hard-rock band used to sniff a combination of Halcion and cocaine, which they dubbed 'Zombie Dust'.

Summary
Triazolam is an extremely potent, ultra-short-acting benzodiazepine prescribed for short-term treatment of insomnia (7-10 days maximum). It was withdrawn from the UK market due to high incidence of psychiatric adverse reactions including amnesia, confusion, paradoxical agitation, and hallucinations. Risk of complex sleep behaviors (sleep-driving, sleep-eating) and severe anterograde amnesia is higher than most benzodiazepines.

A month ago, a filling fell out of one of my molars. The dentist told me that he wasn't sure, but I might have to have a root canal. As he brought the Novocain needle towards my mouth, I began to panic and started crying.
I don't know how many people will be cruising over to the triazolam section of erowid, given the vast quantity of way more interesting things, but I did. So I might as well give an account of my experience with this drug.
Due to the limited amount of information about Triazolam (Halcion) available, I felt the need to post this experience in full detail. I've been a fan of sleep-inducing pharmaceuticals for many years. Long, clean sleep is something I find myself taking for granted.
Ahhh The refreshing smell of a benzo in my nose yo. So I am avid with benzo I have yet been able to take Xanax that will actually make me buzz. I have maxed at 13 mg of Xanax with no effect besides post amnesia very mild.
First off, I'm no stranger to benzodiazepines. I've used a few to date varying from Klonopin and Valium, to Xanax and recently Triazolam. On this occasion I obtained about 30 or so tiny pills of Triazolam (.125mg/each).
In the '70s I was a young social worker doing general "family support" work with families on welfare. A client of mine--let's call her Cathy, because that's not her name--had been doing extremely well in an external sense: Managing her limited money well, taking great care of her two kids, and keeping her apartment spo...
[Erowid Note: Driving while intoxicated, tripping, or extremely sleep deprived is dangerous and irresponsible because it endangers other people. Don't do it! ] I took 4 0.125mg Halcion tablets outside the pharmacy and started to drive home.

Exploring the outer limits with Halcion (triazolam) 5:20 PM- Ingested 2 mg triazolam in the form of 8 .25 mg tablets. (I am writing this as the effects develop) Halcion is by far my favorite benzodiazepine in terms of abuse. It hits me fast and hard, and produces a distinct "rush" that other benzo's don't.
