The use of psychoactive and non psychoactive drugs before having sex at raves, orgies and chemsex parties. The drugs most commonly used for chemsex are katamine mixed with cocaine or speed (coketa), methamphetamine (crystal meth, batu, blade, hot ice, ice, shabu, stove Top, Tina, and crank), mephedrone (meph, mefe, 4-MMC, meow meow, m-Cat, bounce, bubbles, mad cow, and drone) and/or GHB (G, Gina, geebs, liquid E or liquid ecstasy, Georgia Home Boy, scoop, easy lay, cherry meth) and GBL (blue nitro, firewater, gamma G, paint stripper, GH-gold, liquid go, thunder, X-12). Boner drugs such as sildenafil, tadalafil, and vardenafil can also be layered into the chemsex mix, as well as amyl nitrite, butyl nitrite, cyclohexyl nitrite, isobutyl nitrite, isopropyl nitrite, and pentyl nitrite (poppers, Amy, kix, liquid gold, locker room, rave, rush, snappers, thrust, TNT). How do we know what drugs are being used for chemsex? In addition to reports from the field, a review about chemsex in a leading neuropharmacology journal stated that these are the drugs that are “commonly encountered during forensic examination of living and deceased subjects in recreational and sex scenes.” Besides rectal trauma, penile abrasions, and a significant increase in the risk of sexually transmitted infections such as HIV, consent is a frequent casualty of chemsex.
