Vancouver police warn of increase in tainted beverages

Vancouver police are warning the public, particularly women, to keep an eye on their beverages following an increase in reports of females being drugged at bars and parties.

According to police, women are often drugged by men that they know.

“Of course the intent of someone doing this is to incapacitate their victim to the point where they’re not able to give or withhold consent and then commit a sexual assault,” says Constable Brian Montague.

Some common symptoms of being drugged include light headedness, confusion, acting out uncontrollably and hallucinations.

Police advise to never leave your drink unattended and to throw it out if you’re unsure. Additionally, try to stay with trustworthy friends no matter where you’re heading.

One of most common date rape drugs is GHB, or gamma-hydroxybutyric acid, an anesthetic occasionally used to treat conditions including insomnia and depression. Sometimes known as liquid ecstasy, it is also taken recreationally as a stimulant and aphrodisiac at raves or dance parties.
