This market resolves YES if the Drug Enforcement Administration announces before November 5th that it intends to remove Marijuana from its current Schedule I Drug status. 

This would likely be in the form of a Notice of Proposed Rule-making, after which there would be some weeks or months for the public to comment on the proposed rule. This market resolves based on when the initial DEA announcement is made, regardless of what happens after that or how long it takes.

If there is no such announcement before November 5th, this market resolves NO.
