A breathalyzer won't detect that you just ate 4 Benedryls and hopped behind the wheel. Blood and hair tests are invasive and illegal and, really, unnecessary. I saw a guy convicted of a DUI who blew UNDER the limit, but failed every other sobriety test.
Further, Marijuana is NOT solely a recreational drug; it has proven medical uses.
