The CURE Act (Cannabis Users' Restoration of Eligibility Act) prevents federal agencies from denying security clearances or federal employment to people based solely on past marijuana use. The bill amends existing law to explicitly exclude marijuana from being considered in security clearance eligibility and federal employment suitability decisions. Within one year of the law's enactment, all federal agencies must establish a review process for past clearance and employment denials made since January 1, 2008, to determine if marijuana use was the sole reason for denial. When someone requests reconsideration under this process, the relevant agency has 90 days to review and determine whether the original decision was based exclusively on past marijuana use. This legislation affects federal employees, contractors, and anyone seeking security clearances or federal employment, potentially allowing thousands of people previously rejected on marijuana grounds alone to reapply or be reconsidered for positions.
