Pay attention to the initial symptoms of GHB exposure. Sudden relaxation, dizziness and drowsiness are among the first signs that someone is on GHB. These symptoms can be similar to alcohol intoxication, so it can be difficult to detect GHB poisoning in the early stages.
Notice the intermediate signs. Trouble breathing, vomiting and failing eyesight are among the intermediary signs that someone's been exposed to GHB.
Take immediate action with advanced symptoms. High doses of GHB can lead to seizures and unconsciousness. Untreated, this can lead to coma or even death.
Call the police to report GHB poisoning and arrange for an ambulance to take you to the hospital.
Get tested as soon as possible. Traces of GHB can vanish from your body within a day. For this reason, it's important that you immediately talk to your doctor if you think you've been exposed to the drug.
Take time to rest and recover. Even if you weren't the victim of a sexual assault, GHB can have lasting physical effects, especially at high doses.
Consult experts for further advice. ProjectGHB is a great source of information on GHB (see Resources below). The Department of Health and Human Services' 4Women website maintains lots of information and advice on GHB and other common date rape drugs (see Resources below).
