It's the first of its kind: a job fair for prospective employees in the cannabis industry.
Sister station KCNC reports that hundreds were lined up for the start of the job fair at 11 a.m. Thursday. The job fair runs until 7 p.m.
More than a dozen Colorado marijuana-related companies are joining forces to recruit hundreds of people 21 and older for positions in accounting, technology, advertising and selling the now-legal drug.
According to the Denver Post, use of marijuana is prohibited in line or at the fair.
