Gee instead of just frowning at my post read what I'm saying. Since marijuana is classified as a schedule 1 drug testing on it for anything is very limited by law. That's why this letter title talks about reclassification. The president could reclassify it with an executive order. Since many states and Washington DC legalized marijuana for recreational uses under obamas presidency and he didn't care I really thought he'd send a signal on the federal level and move it out of the schedule 1 classification. If it was not schedule 1 it could be grown and tested widely for more medical uses by pharmaceutical industries.
