Anti-Intoxicant

An anti-intoxicant is a medicine that allows one to drink alcohol without experiencing the effects of inebriation. Benjamin Sisko and his infiltration team treated themselves with anti-intoxicants before attending the induction festivities for the Order of the Bat'leth, a celebration where copious amounts of Klingon bloodwine are traditionally consumed. Without the drug, Worf claimed that they would have been so drunk they wouldn't have been able to walk. (DS9: "Apocalypse Rising")
