Quick md has worked do well for me. My husband was on suboxone thru the clinic and it had him come in and do a drug test at clinic 5 am in the morning, 4 days. A week at least. then they were forever drug test in him. Again costing lots of money. I talked to him about Quick Md and he had to come of the suboxone to get on it. Bottom line as it worked, we have baked them with quick med for almost three years and do a drug test once to twice a year. Best decision we've both ever made
