I'm afraid it's not as simple as you think Do you know that drug testing can only be done by medical testing centers designated by the state? It is estimated that a set of testing items will cost thousands of dollars. Do you think it is necessary to do this test for a drug with a few cents? Since you don't believe in small clinics, let's go to a regular hospital. A box of 20 tablets of estazolam (a specific drug for insomnia) costs about 9 yuan. If you are worried, don't let your father eat it. It won't cost much to go to the hospital to prescribe medicine.
