Could this be a excuse after being drug tested?

LOL my area of expertise. Depending on how much you smoke depends on the THC level you have in your body. When you take the test there is already a small percentage that they expect you to have because your body generates a small amount but if you been blowin everyday and then took the test they will know. They can see the amount in your test to know whether its a high or low level. Now if you smoke every now and then, it takes 2-4 weeks to clear and if you didnt smoke 1-3 days before, you may be able to use that excuse. I would try. Now this is what us big dogs in the military do. Pop Niacin it works! You have to get the regular one, you cant get the one that dont burn cause it dont work. if you wanna smoke you gotta do the time and take the itching and burning that comes wit niacin. It wont last long depending on the person. Take 2-4 Niacins depending how much you smoke. You can also use cover ups, they have them at GNC, dont be afraid to ask they will recommend the best one. you are not the only person who is asking! Hope that helps and SMOKE ON!
