<s>[INST] I work in a place where random urine tests are the norm and we are not supposed to take champix because of the possible side effects, my question is, would champix or it s ingredients show up in a urine test? They test for recreational drugs, and we are barred from taking codeine too. [/INST] Hello, Champix contains nicotine and nicotine will show in your urine for up to 3-4 days after you stop taking it. So you should be careful. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr. Prabhash Verma, General & Family Physician </s>
