Be aware of rape drugs.
Try not to leave your drink unattended.
Only drink from unopened containers or from drinks you have watched being made and poured.
Avoid group drinks like punch bowls.
Cover your drink. It is easy to slip in a small pill even while you are holding your drink. Hold a cup with your hand over the top, or choose drinks that are contained in a bottle and keep your thumb over the nozzle.
If you feel extremely tired or drunk for no apparent reason, you may have been drugged. Find your friends and ask them to leave with you as soon as possible.
If you suspect you have been drugged, go to a hospital and ask to be tested.
Keep track of how many drinks you have had.
Try to come and leave with a group of people you trust.
Avoid giving out your personal information (phone number, where you live, etc.). If someone asks for your number, take his/her number instead of giving out yours.
