US reviewing Musk's security clearance over weed use: Report

Elon Musk's federal security clearance is reportedly being reviewed by US officials after the billionaire smoked weed in a podcast last year. Musk had reportedly refiled his SF-86 security form, which requires federal employees or contractor seeking a clearance to acknowledge any illegal drug use over the previous seven years. Musk's aerospace startup SpaceX has been contracted by NASA.
