Now, glassware that detects 'date-rape' drugs

Researchers have designed new glasses, cups and straws that can warn if your drink is spiked by changing colour as they come in contact with three common 'date-rape' drugs.
The US researchers created a line of 16-ounce cups and straws that change colours when they come in contact with common 'date rape' drugs like ketamine, Rohypnol and GHB.
In an attempt to reduce drug-facilitated sexual assault, DrinkSavvy founder Mike Abramson teamed up with chemistry professor John MacDonald at Worcester Polytechnic institute in Massachusetts to develop the glassware.
Abramson decided to create the glassware line after he was himself affected by the date-rape drugs, 'New York Daily News' reported.

"Within the past three years, three of my close friends, and myself have been unwitting victims of consuming an odourless, colourless and tasteless drug slipped into our drink," Abramson said.
"That is why it is our goal to have as many bars and clubs as possible to simply swap out their current drinkware for DrinkSavvy drinkware, making it the new safety standard," said Abramson.
In case the drink is safe to sip, the cup will remain in its clear state, and if the beverage is spiked, red stripes will appear on the cup. The DrinkSavvy straw operate in the same manner.

"They're discrete, because they look and function just like any other cup, straw, stirrer or glass," Abramson said.
