Marijuana will remain a schedule l controlled substance, which declares it has "no now accepted medical use and a high potential for abuse", the Drug Enforcement Administration said Thursday. It's passed due that we expand opportunities for medical research, and now the DEA needs to take the next step and remove marijuana from schedule I. In order to have more research, scientists need to do more studies.

DEA chief Chuck Rosenberg told NPR on Wednesday that "this decision isn't based on danger".

For years, the University of MS has been the only institution authorized to grow the drug for use in medical studies. She said it was "very disappointing" that the DEA had failed to recognize that the drug had any therapeutic value.

"Science has been shackled by politics for decades".

Sabet said the ruling would "raise eyebrows in the legalization community" among those who had pressured the DEA to reschedule marijuana but added: "This now sets them way back". It stated it will break the monopoly the University of MS now has on research-grade marijuana. Legally, that prohibits the DEA from reclassifying the drug. However, researchers could only find "little evidence" to support theories that marijuana is "gateway drug".

She also viewed Clinton's choice of vice presidential candidate Tim Kaine, a popular Virginia senator, as "a positive". She is the current CEO of Hewlett Packard Enterprise and reportedly has a net worth of over $2 billion.

Drug policy advocates, experts, and researchers believe that increasing the number of institutions growing marijuana will help speed up the reform of marijuana laws. The drug is now listed on Schedule I, meaning that it is viewed as having "no acceptable medical use in treatment", and is therefore banned in the United States. However, the agency will permit new suppliers to boost the quantity of marijuana available for study.

"While I haven't read it, the outcome is totally out of touch with the Justice Department, research, the medical profession, patients and the public".

This announcement conflicts the federal goverment's stance on medical marijuana with that of 25 states and the District of Columbia that have legalized the use of medical marijuana. Advocates have tried to change this classification, but the USA government has repeatedly rejected such appeals.

A downgrade to the lower Schedule II category would have placed marijuana in a less tightly regulated class of drugs but it would have remained on par with other highly addictive substances such as cocaine, methamphetamine and oxycodone. "It's illegal and could be removed from us at any time". California and eight other states have ballots scheduled for this year that will decide whether or not they will also lift any legal restrictions against recreational use.
