Rohypnol, 'roofies', rophynol (flunitrazepam) I have ingested Rohypnol primarily by swallowing and snorting. The pill itself is sweet and can be chewed. Snorting produces no pain whatoever, resulting in a quicker and more potent 'high'.

Summary
Flunitrazepam (Rohypnol) is a benzodiazepine and central nervous system depressant. Like other benzodiazepines, it acts on the GABA-A receptor, enhancing the effects of the inhibitory neurotransmitter GABA by increasing GABA's affinity for the receptor; this opens the chloride channel and hyperpolarizes the cell membrane to prevent further excitation. It is extremely potent, approximately 10 times stronger than diazepam by weight, with pronounced hypnotic and amnesic properties, causing severe anterograde amnesia at therapeutic doses and sometimes producing delusions of sobriety despite severe impairment. It is notorious for its association with drug-facilitated sexual assault.

Based on reports from:
Tolerance
Build-up
develops over 1–4 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 — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Clinical and community data indicate tolerance to hypnotic and anticonvulsant effects develops over weeks with regular use and decays over 1–4+ weeks after cessation; data are approximate and interindividual.

The first time I took Flunitrazepam was funny. They were brought by a friend who came and picked me up at school. We left to a rather smallish town afterwards and I took a pill. Never in my life I felt really sleepy, I could sleep anywhere! So it was in the laps of my friend at a bar. I woke up and was semi-conscious.
I like to do benzos occasionally and just happen to come by some flunitrazepam by chance. Roofies are hard to find where I live so I jumped at the opportunity and bought a blister pack of 10. I didnt have work for the next two days so I decided to take some later that night.
I would like to talk and share my experience of using sleeping pills to get high. Vulbegal and Hipnosedon are very strong pharmaceutical drugs used to cure anxiety, insomnia and people with psycological problems. Also used as a substitute of heroin.
My experiences with the benzo-family so far had covered diazepam and alprazolam while I prefer the latter as it doesn't last as long and I somehow like the effects more, even though they're pretty equal.
I was upstairs alone in my dope lair experimenting. I had some Rohypnols which I had heard a great deal about ('the date rape drug') and decided I would try one for myself. For some reason I chewed it instead of simply swallowing it.
Goofy roofie DOSAGE Rohypnol is prescribed as a sleeping aid, and it does work wonders in that respect. If you take one and want to sleep, you'll be sleeping like a rock within an hour (the drug kicks in in about 20min).
I would like to tell you about my addiction to roofies and alcohol. I am a male in my early twenties living in Sweden. I have been drinking alcohol heavily since I was thirteen, only recently I have stopped drinking much, but I still binge sometimes.
