What is Rohypnol?

Rohypnol (or Roofies), the trade name for flunitrazepam, is an inexpensive drug intended for use in treating sleep disorders, such as insomnia. Because of its cheap street price, people occasionally take Rohypnol recreationally. The effects are similar to Valium but around 10 times the strength.

It’s also occasionally used as a ‘parachute drug’ to lessen the effects of coming down from other substances.

How do you take Rohypnol?

Rohypnol is sold on prescription in bubble packs of one or two mg doses (usually in the form of white tablets with the word ROCHE written across).

Rohypnol and date rape

Because Rohypnol dissolves quickly in drinks leaving no odour or taste and often leads to blackouts when mixed with alcohol, it has also become known as the ‘date rape’ drug. Despite the manufacturer’s attempt to counter this problem by adding blue dye, and making it slower to dissolve, there are plenty of roofies that contain no such warning ingredients.

Remember to watch your drink when you’re out, and if you think you’ve been spiked, call 999.

Why do people take Rohypnol?

  • Rohypnol takes effect within 20 to 30 minutes of administration and lasts up to eight hours.
  • It induces memory loss, relaxes the muscles and slows down the body’s responses.
  • Tolerance is likely with repeated use, which means you need more to get the same effect.
  • If combined with heroin, Rohypnol can enhance the high.
  • If combined with cocaine, Rohypnol can mellow out the kick.
  • If combined with alcohol, Rohypnol can increase the feeling of drunkenness and lower inhibitions.

What are the bad side effects of taking Rohypnol?

  • Continued abuse of Rohynol can result in physical dependency.
  • Withdrawal symptoms may include headaches, muscle pain, confusion to hallucinations, and even convulsions. Seizures may occur up to a week after users have quit.
  • Experts advise controlled withdrawal under medical supervision.
  • If you’re abusing Rohynol or any other benzodiazepine. Consult your doctor before trying to kick the habit.

How can I reduce the risks if I take Rohypnol?

Avoid mixing with any other drugs, particularly other depressants such as alcohol and heroin. Remember that Rohypnol is not a substitute for temazepam, it’s actually much stronger than temazepam, and much more toxic too. You may only need half a tablet to get the same effect as a jelly.

Is Rohypnol legal?

Rohypnol is a Class C drug. It’s available by prescription only, so supply or possession without a prescription is a criminal offence. The maximum penalties are two years in prison and a fine for possession, or five years prison and a fine for possession with intent to supply.

Spiking someone’s drink to try and have sex with them can get you 10 years in prison.
