Other Impacting Laws (e.g. drug testing, workers’ compensation, unemployment)

- Unemployment denial – Benefits will not apply if the discharge is due to, (Colorado Revised Stat. 8-73-108(5)(e)(VIII)) “…off-the-job use of not medically prescribed intoxicating beverages or controlled substances…” “…to a degree resulting in interference with job performance;” or , (Colorado Revised Stat. 8-73-108(5)(e)(IX)) “…on-the-job use of or distribution of not medically prescribed intoxicating beverages or controlled substances,” or a positive drug test per Colorado’s code.
- Workers’ compensation denial – Benefits will not apply if the injured employee has a drug test result that is positive, at such a level, (Colorado Revised Stat. 8-42-112.5(2))“… it is presumed that the employee was intoxicated and that the injury was due to the intoxication.”
