GHB drinks contained a 30 ml answer consisting of a mixture of GHB option (at the volume supplying the intended dose) and sodium citrate solution, to which 370 ml deionized water and 600 ml of cranberry juice cocktail (Ocean Spray; LakevilleMiddleboro, MA) have been added, bringing the total solution volume to 1000 ml.PMID:23880095 Ethanol drinks contained 30 ml sodium citrate resolution, to which 370 ml was added consisting of a mixture of ethanol (in the volume offering the intended dose) and deionized water.
