What is Rohypnol?

Rohypnol is a powerful benzodiazepine and acts as a central nervous system depressant. It has become widely known as the  “date rape” because it has been used to sedate potential victims. In a medical setting, it has been used to treat insomnia  and a precursor to anesthesia in some countries outside of the U.S.

How is it Used?

Royphonol is commonly taken orally in tablet form but has also been used to sedate potential rape or sexual assault victims by dissolving the tablet in liquid. It has been known to be insufflated nasally.

What Does It Look Like?

Small white tablet. Royhpnol also comes in long oblong shaped tablet that is green in color and contain traces of blue dye inside of them. This was manufactured to combat potential sexual assaults or other crimes related to some one being unknowingly dosed with the drug.  It is otherwise ordorless and tasteless leaving it difficult to know when consumed. 

What Are the Effects?
When taken properly an extended-release tablet will usually produce onset effects within 30 minutes to 1 hour and can last anywhere from 4 – 12 hours gradually “releasing” the dose over an “extended” period of time. The immediate-release tablets will have shorter acting effects last from 2 – 4 hours but “release” the entire dose all at once or “immediate(ly)”. Oxycodone has been said to produce euphoric pain relieving effects that have helped many improve quality of life, but has a high risk of dependency and can also be fatal at high doses. Users are often encouraged to be weened off oxycodone, due to the withdrawal symptoms that can follow abrupt stopage
