Huffington Post:  “Sen. Patrick Leahy (D-Vt.) reached out to Gil Kerlikowske, director of the Office of National Drug Control Policy, on Thursday in an effort to find out how the federal government intends to deal with states like Colorado and Washington that have recently legalized marijuana possession.  In addition to seeking clarity about the administration’s plans, however, Leahy also offered a solution to allow the government to extricate itself from the situation of having to enforce federal laws that consider marijuana to be an illegal substance.  ‘One option would be to amend the Federal Controlled Substances Act to allow possession of up to one ounce of marijuana, at least in jurisdictions where it is legal under state law,’ Leahy wrote.
