Would Dextroamphetamine also give you a positive test for Meth?
Yup! Amphetamine is amphetamine is amphetamine!
A bit off-topic, but interesting none-the-less! Back in the "old" days we used to give calamphetamine i/v to cows that were reluctant to get up after treatment for "milk fever". Worked a treat, but you had to be quick on your feet cause they got a bit excited!
Alas, it was taken off the market when it became popular as a recreational drug!
