As a candidate, Donald Trump promised rural towns and states hit hard by opioid addiction that he'd solve the epidemic ravaging their communities. "We will give people struggling with addiction access to the help they need," Trump vowed in October. Trump won many of those communities — often overwhelmingly. But as president, he's proposing deep cuts to research and treatment in favor of funding a border wall to stop drug traffic, while hinting at bringing back policies like criminalization of drug misuse — and announcing Wednesday yet another big presidential commission to study the problem.Public health advocates say those plans at best duplicate those of the Obama White House and at worst could set back efforts to tackle a problem that contributes to more than 47,000 deaths per year.
