Quinine is not an illegal substance, but it is often tested for in the drug screening process. This is because Quinine is often used to "cut" drugs such as heroin and cocaine. As a result, the presence of quinine can lead to a false positive, or screening failure, but not because it tests as either heroin, or cocaine. While simply drinking tonic water, or gin and tonics should not be enough to cause concern, it might be best to list such libations on the drug screening form prior to providing a sample.
