Will adding table salt to urine pass a home urine cotinine test?

Adding table salt to urine will not effectively mask the presence of cotinine in a home urine test. While some substances can potentially interfere with drug tests, salt is unlikely to alter the chemical composition of urine enough to evade detection. Moreover, drug tests are designed to identify specific metabolites, and tampering can often be detected. It's always best to avoid smoking or using nicotine products if you want to pass a cotinine test.
