Dear Mohammad: Just as an aside, whenever someone asks me if I can determine whether some unknown substance is present, my response is: "Tell me what you think it is, and I may be able to determine whether you are right or not." Rohypnol (flunitrazepam) and GHB are the two most common "date rape" drink additives (in the U.S.), and urine tests are available for both, but the window of detectability is fairly short. Some benzodiazepine immunoassays do not detect flunitrazepam; others detect it weakly. GHB is usually detected by GC-FID or GC-MS. I agree, though, that drugging someone's drink is a crime, and its investigation should be in the hands of law enforcement officers, not clinical laboratories. That is the advice I have given on at least two occasions when approached with a question similar to yours. Kind regards, Roger Roger L.
