Rohypnol (AKA roofies, date rape drug) is a prescription sedative (not approved for use in the United States) that has no taste or odor when dissolved in a drink.63 It causes users to feel drowsy, forgetful and spacey.
Rohypnol is more dangerous when mixed with alcohol. Rohypnol can cause a kind of amnesia – users may not remember what they said or did while under the effects of the drug, making it easier for others to take advantage of them.64
You can become dependent on Rohypnol.65 Withdrawal symptoms range from headache, muscle pain, and confusion to hallucinations and convulsions.
