Does hair drug test determine when a drug was used?
No, but it gives an estimate. Drug tests test the presence of substances the body makes when processing the drugs. In blood or urine tests, most of these substances don't linger very long until they dissappear completely. In hair, since these grow slowly and don't deteriorate, drugs can be found much longer after use. Specific times differ from drug to drug, but it's never safe to say that they can't find any traces of the drug by tests or searches. In most countries, the legal basis for these tests is quite strict though, so you'll porbably never really encounter one.
