You will not test positive for ADHD prescription medicines at the roadside using a drug screening test. The four drugs being tested for at the roadside are: THC (cannabis), methamphetamine (meth), MDMA (ecstasy), and cocaine.

The roadside device does not test for amphetamine; and will not cross-react with any ADHD medicines.

Methylphenidate is not tested for at the roadside or in the laboratory. Amphetamine-based ADHD medications can be tested for in the laboratory (they will not test positive roadside).
