... I have been taking Concerta 54 mg for 2 years.For the last 6 months I have been given a urine screen test at my doctor's and it comes back negative for amphetamines. I also had a blood test done last month and it was negative. I KNOW I AM TAKING THE MEDICATION. Has anyone else had this problem?
Is it possible to test negative on urine and blood tests for amphetamines?
