“The straw can currently detect the two most common drugs being used, ketamine and gamma-hydroxybutyric acid, of GHB. Patolsky and Ioffe are working on adding more drug detection abilities, including rohypnol, aka ruffies.

The idea is that women will carry the straw with them when they go out, and they can reuse the straw as many times as they like until the straw encounters the presence of any date rape drugs. If the straw detects any drug in the drink, a chemical reaction will be created and the straw will change colour, depending on the drug.”
