Attorney General Jeff Sessions decided to abruptly rescind an Obama-era guideline on legal marijuana known as the ‘Cole memo’ which outlines the federal government’s enforcement priorities for pot, while specifically omitting an outright ban on the sale and distribution of it altogether. This prompted swift and severe backlash from states that have legalized marijuana, as the $10 billion dollar industry is an economic boon, and Sessions is signaling that he now wants to pull the rug out from under them.
