Taking controlled prescribed medications

A good and sufficient reason for failing a drug test obligation includes when a partner is taking prescription medication correctly.

Not all prescribed medications will affect the results of a drug test. Generally, only controlled prescribed medications do, such as morphine, codeine or medicinal cannabis. Controlled prescribed medications need to be used correctly to the dose the health practitioner recommends and by the person for whom they are prescribed.

Some controlled prescribed medications may cause a person to be impaired on the job which can cause health and safety issues for employers.

In some situations, screening drug tests can show failed results if controlled prescribed medications have been used.

The partner can be asked to provide verification from a registered health practitioner that they are taking a controlled prescribed medication. There is a Drug test obligations verification form [no link find out why] that MSD can provide to the partner.

Note when a partner is asked to take a drug test they will be asked to declare any prescribed medications they are taking.
