Do drug test strips give accurate results?

Question
Hello doctor, I have a question that I need your advice on. How long does the drug last in the body, if it's been about 90 days, try it with a drug test strip to be accurate or you have to go to the hospital for a new test to be accurate. Thank you doctor.

Hi, usually drugs that last for 24 hours will be eliminated. To determine exactly you need to go to the hospital for a urine test.
