Workplace Drug Testing Laws in Pennsylvania

The state of Pennsylvania is considered an "open" state as it pertains to employee drug testing laws. There are currently no statutes or employer regulations that restrict how drug and alcohol testing may be completed for workplace purposes. However, Pennsylvania employers who hire for safety-sensitive positions, such as those that must possess a commercial driver's license (CDL), may have mandated testing and should always review their organization's policy first.

Although no Pennsylvania employee drug testing laws are in place, it's best for employers to establish and outline a drug-free workplace policy if they wish to conduct applicant and employee drug testing. A detailed layout of your company's drug testing policy can help educate employees and applicants on expectations to further reduce the chance of workplace complications.

Conditional Pennsylvania Drug Testing Laws

Drug Test Issue Remarks
Recreational Marijuana Under current Pennsylvania legislation, the recreational consumption of marijuana is prohibited. Likewise, there is no state legislation that prevents employers from conducting marijuana drug screenings. Some exceptions apply, such as Philadelphia's Chapter 9-5500 law, which prohibits pre-employment marijuana testing as a condition of employment except under specific conditions.
Medical Marijuana In 2016, the state of Pennsylvania passed legislation that legalized the consumption of marijuana for medical purposes. On a state level, there are no established employee drug testing laws that restrict employers from conducting marijuana drug testing. On the other hand, the city of Philadelphia passed legislation in 2020 that prohibits employers from testing applicants for the presence of marijuana with certain exceptions for specific safety-sensitive sectors.
