Worked on an instant test.
This stuff saved by bacon. I am a habitual smoker and had just less than 48 hours to prepare for a test. I am a bigger guy and since I smoke just about every day, I though no way this would help me pass, but I passed. One caveat though, it was an instant 5-panel stick test. I can't promise this would work on a full lab test, but for the quick tests, works like a charm.
