The Marquis reagent is used by police all over the world to test pills for amphetamine and various drugs. What the police don't know, is that this test isn't fool-proof. The test reacts even to glucose in the same way it would with amphetamine, so basically even if they test a pill with vitamine-C (that has glucose in it), the test will show positive for amphetamine. —The preceding unsigned comment was added by Mr Soros (talk • contribs) 09:52, 4 July 2007 (UTC).

Please provide a source for that claim. Also keep in mind that the Marquis reagent test is generally only used as a preliminary test. Forensic tests such as GC/MS are much more reliable. Simishag 21:18, 4 July 2007 (UTC)

Yes, I know I don't have any sources, which is why I only added this to the talk page: I have not yet found any sources for this on the internet. But I still want people to be able to find this information, because it can be vital. For me for example, it is, because I have been found with 12 pills of vitamin-C by the police, who tested the pills with this test, and the test showed positive for amphetamine (brown).
