Missouri is becoming home to a less pleasant epidemic. With the rise in methamphetamine-related incidents decreasing in other Midwest states, Missouri remains the leading state for meth-related overdoses and substance abuse. The numbers of residents struggling in Missouri reported the use of cocaine, meth, heroin continue to grow and many of those seeking treatment or counseling are also reported as seeking help for issues with alcohol abuse.

The rise in drug and alcohol use and the increased need for treatment and testing has brought a demand for more drug testing centers in Missouri. US Drug Test Centers provides everything from EtG hair follicle testing, urine testing, DOT drug testing and more. All of our tests can conveniently be purchased online.

Drug Testing in the Workplace

Missouri is one of a small number of states that has no law addressing drug testing in private employment. This means that drug testing is not prohibited or restricted. Employers can implement drug testing programs. However, employers must also meet certain drug testing requirements in order to challenge workers' and unemployment comp claims.

To deny unemployment claims employer drug testing policies may be publicized to employees through posting a written personnel policy or handbook, or inclusion in a collective bargaining agreement, and "must state that a positive test may result in suspension or termination of employment." As long as the written substance abuse prevention policy states that employees may be subject to random, reasonable suspicion, and post-accident drug and alcohol testing, the test results shall be admissible.

For detailed information on how to deny a worker comp claim for a positive drug test after an accident, contact one of our drug testing specialists at US Drug Test Centers, or visit the Missouri Revised Statutes Section 287.120.1. Injuries that are caused by an employee’s consumption of alcoholic beverages or illegal drugs are generally not compensable unless the work necessitated that the employee consumes alcohol. Injuries that are not caused by the consumption of drugs or alcohol, but that occur while the employee is using drugs or alcohol can result in a 50% penalty being levied against the employee.

The Missouri law allows employers to require and, with notice admit for unemployment purposes, pre-employment alcohol and controlled substance testing. In addition, the law's application is extended from only reasonable suspicion tests to any random, reasonable suspicion, and post-accident drug and/or alcohol-test result in violation of an employer's policy. Any positive result shall be treated as disqualifying misconduct.

An employer may acquire tests for employees having been convicted of any criminal offense involving an illicit drug, if a work-related accident takes place and suspicion of drug or alcohol consumption is suspected or for random purposes. As an employer, you have the right to test your employees to ensure a safe and productive work environment. Learn more about implementing a drug-free workplace policy.
