Rohypnol (aka “Roofies”, flunitrazepam, Mexican Valium) is a benzodiazepine
originally produced by a pharmaceutical company as an anti-anxiety medication.

Short Term Effects of Rohypnol

Rohypnol acts on GABA receptors in the brain and depresses neuronal activity. This leads to reduced anxiety, less muscle tension, and a lessening of inhibitions.

Short Term Damage

At higher doses, Rohypnol causes the user to lose muscle control and even consciousness. During intoxication, new memories are not formed, so users experience a brief amnesia.

Rohypnol is illegal in the United States, but sold commercially in many countries.It is odorless, flavorless and highly soluble in beverages, which makes it an especially dangerous drug in the commission of date or acquaintance rape.

Long Term Damage

It is very easy to become addicted to Rohypnol.  In fact, some studies suggest that it is more likely to cause dependence than other benzodiazepines.

There can be withdrawal effects when dosing stops. Rohypnol withdrawal can lead to delirium, headache, muscle pain, anxiety, and an increased risk of seizures.

Rohypnol Overdose

Very high doses of Rohypnol lead to:

  • Moderate amnesia
  • Loss of consciousness
  • Respiratory depression

When consumed with alcohol, the effects can be fatal.

Symptoms and Signs of Rohypnol Addiction and Abuse

During intoxication with low doses, chronic users of Rohypnol may seem simply at ease and relaxed. Higher doses will make the person seem as if they are drunk on alcohol.

Between Rohypnol doses during times of withdrawal, chronic users will seem to have a hangover (e.g. headache, sensitive to light, irritable). Unexplained seizures could be due withdrawal due to a rohypnol addiction.

Adverse Interactions

The most important and dangerous drug interaction with Rohypnol is alcohol. The two chemicals act together (synergistically) to depress the central nervous system.
