Colorado Drug And Alcohol Testing

The state of Colorado, like many in the United States, is struggling with the influx of illicit substances and the impact of drug and alcohol use. In 2015, Colorado was ranked the highest in the country for use of opioid painkillers, alcohol, cocaine and marijuana.

Additionally, in 2015 there were more deaths in Colorado as a result of drug and alcohol abuse than by car crashes. The rate of fatalities from opioid overdoses increased by more than a multiple of three between 2000 and 2015.

Marijuana Use in a Legalized State

Countless employers in Colorado are implementing drug testing programs, during the hiring process, to filter our potential employees who smoke marijuana. Although medical marijuana and recreational marijuana are legal in Colorado, employers have every right to implement and maintain a drug-free workplace program, which includes testing for marijuana (medical or otherwise). Recent studies show an increase in the number of employers who have established drug testing programs in the workplace since recreational marijuana use was legalized in 2014.

The Colorado Supreme Court has issued a ruling on the topic of medical marijuana and employment practices. In Coats v. Dish Network, an employee sued for wrongful termination after he tested positive for marijuana. The plaintiff is a quadriplegic who used medical marijuana outside of working hours. Mr. Coats was a registered medical marijuana user, accessing the product in a manner consistent with state constitutional guarantees and state statute. The use of marijuana is still illegal under Federal law. Dish Network has a comprehensive drug free workplace policy. The court held in a unanimous opinion that the term "lawful activity" extends to both state and federal law.

According to Federal law, marijuana is a schedule I drug. Under that classification, marijuana "has a high potential for abuse…has no currently accepted medical use in treatment in the United States [and] there is a lack of accepted safety for use of the drug or other substance under medical supervision" [21 U.S.C 812(b)(1)].

Employers in the state of Colorado have a right to implement a employee drug testing program. The state of Colorado imposes no restrictions except in the City of Boulder. US Drug Test Centers offers both DOT and non-DOT drug testing programs for employers in Colorado. Setting up a workplace program is simple and affordable with your testing specialists from US Drug Test Centers.
