Other useful information

  • GHB is used as a party drug. However, it is also used to commit crimes, hence its nickname "date rape drug". Its nickname is the result of its properties which include amnesia, state similar to drunkenness and very short duration of action. GHB does not have any aphrodisiac properties as such, but can cause a loss of sexual inhibition.
