[Effect of home-made narcotics on infectious activity of HIV-1].

The stability of human immunodeficiency virus, type 1 (HIV-1), strain IIIB, was studied in liquid preparations of homemade drugs. The "Vint" preparation (containing Methamphetamine and obtained from Ephedrine) as well as "Khanka" (a liquid surrogate opiate made from poppy straw) were analyzed within the case study. HIV-1/IIIB was shown to maintain its infectious activity in "Khanka" at room temperature for least 7 days.
