I did white cross speed back in college. It was supposed to be pharmaceutical. I don't know how close that is to meth but it's the closest I ever went. I could stay up for days with a couple of white crosses. Edit: Here is what I found about White cross. It's the internet so it's fact. White cross is Dextro-amphetamine sulfate. It is still commonly available under trade names Dexedrine and dextrostat. However adderall(mixed D/L amphetamine salt) is more common/well known in the USA lately.
