The most common place where this scam is pulled is Venezuela. You go to a local bar, even with a couple of friends, and start drinking.

During the evening, you make new local friends and you might buy them a drink. They would like to return the favor and they buy you one, too. Whether they go to the bar and grab it themselves, or have the bartender as partner, it is reported that they use a substance to drop into your drinks – which will make you senseless for the next three hours.

In Venezuela, the drug is called Burundanga and sedates the victims even by touch.

How to avoid: never accept a drink from strangers unless you see the glass or the bottle at all times.
