The U.S. Drug Enforcement Administration said on Monday that it will move ahead with a long-delayed expansion of its marijuana research program, in a sign that the Trump administration’s hostility to the drug may be waning as a growing number of states have legalized its use. The DEA said it would roll out new guidelines that would allow more growers to produce marijuana for scientific and medical research. The DEA also said producers of hemp, an industrial form of marijuana that has little psychoactive effect, will not have to get a permit from the agency.
