WASHINGTON (CBSNewYork/AP) —  The Obama administration isn't going to reclassify marijuana and remove it from the list of the most dangerous drugs.

The Drug Enforcement Administration said in a lengthy notice in the Federal Register that it consulted with the Health and Human Services Department and concluded that marijuana will remain in the class of drugs that have "no accepted medical use in the United States."

But the agency said it will try to make marijuana more available to researchers, CBS News senior investigative producer Pat Milton reported earlier Thursday.

The agency is opening the door to further medical research of the drug by expanding the number of agencies that can legally grow marijuana for research purposes.
