Foods to Avoid
In addition to supplements and medications, a few foods in the diet would also trigger a false position in a drug test. The list might include tea, tonic drinks, poppy seed bagels, granola bars, as well as yeasty foods. These products contain one or more elements that can be falsely detected during a test. It is better to avoid eating or drinking at least one or a few days before your test takes place. If necessary, have a talk with your healthcare provider to make a better decision. [3]
