GHB has an extremely steep dose-response curve; the difference between a recreational and dangerous dose can be as little as 1-2 grams. Doses above 10 grams are associated with high risk of death. Never combine with alcohol or other depressants. Always measure doses precisely using accurate equipment and wait at least 2-4 hours between doses. GHB is used medically as sodium oxybate (Xyrem) for narcolepsy treatment.
