The strip tests are very accurate. I would say he should pickup a few cheap ones to test himself. Subbing is always the safest bet but there are some people that are able to piss clean pretty quickly. You never know till you test yourself.
killerweed420 Reviewed by killerweed420 on . Varibility of tests A friend of mine smoked for 3-4 months heavily (avg 2 times a day) up until about 15 days ago when he subsequently smoked once every 2-3 days until about 5 days ago. He now needs to pass a drug test in about 2 weeks. Is he screwed? He was thinking of purchasing some at home tests, but said individual test results can vary from test to test. My question is how much variability is there from test to test? If he is negative on at home test will he pass the real one? Thanks in advance... Rating: 5
