Within a few minutes of drinking the liquid, the victim will appear intoxicated and become helpless. The individual coming to her aid will appear a good samaritan to those watching, but may be the one who spiked by drink and is planning to rape the victim. When the victim regains consciousness she will probably have no memory of the attack. Because GHB is quickly absorbed into the human body, evidence will be lost if the victim's blood or urine is not preserved soon after the attach. When going to a bar, party or social event, never go alone.
Friends can watch out for each other.
Never accept a drink from anyone except the bartender and watch your drink being mixed. Don't share or exchange drinks. Never leave your drink unattended, allowing someone the opportunity to slip something into it. If you feel you are becoming severely intoxicated after only one or two drinks, get help. You may have ingested GHB or Rohypnol.
