Pre-Employment Drug Testing Laws By State 2022

Breaking Down Drug Testing Laws State by State

Understanding your job applicants is fundamental to making smart choices when you need to hire talented individuals to join your team. However, it may be important to go beyond a well-rounded background check procedure by asking applicants to submit to a drug test for employment. 

Drug screening is a very common step for positions across the nation. In some states, employers even have the power to carry out random drug tests on existing employees without additional authorization.

The Importance of Pre-Employment Drug Screening

A drug test can help you determine whether someone is trustworthy and safe enough to bring into your business. Serious drug use could impair a new hire’s ability to work effectively. In some cases, it could create serious safety risks, such as in positions involving the supervision of children or the operation of industrial machinery. The purpose of a drug test isn’t to weed out applicants unfairly but rather to protect the business from these risks. Habitual intoxication poses problems for the public, co-workers, and the employer.

There are many times when a pre-employment drug test is a smart addition to the hiring process. However, just as with background checks, there is a patchwork of laws across the nation that define how and when applicants must submit to drug tests. While there are no federal laws requiring drug tests, there are some rules at the federal level that employers must follow—especially in the transit industry.

As background check and drug testing laws vary from state to state, it is key for businesses to understand which rules apply to them and how to use these vetting tools effectively and in full compliance with the law.

Breaking Down Drug Testing Laws State by State as of 2022

What are some of the most notable laws governing the drug test for employment in each state? It’s important to have a clear understanding of your region of operation—for example, in California, you must make a conditional job offer before asking a candidate to consent to a drug test. Just as with the use of background checks, you must have a compliant plan in place for using drug tests.

When Does Federal Law Supersede State Drug Testing Law?

There are some job categories in which federal rules on drug tests apply, and employers must abide strictly by those rules. These rules primarily apply when a position and its duties fall under the purview of the federal Department of Transportation. Generally, if an individual holds a commercial driver license (CDL) and seeks employment from a DOT-licensed provider, they will need to submit to a five-panel pre-employment drug test. 

Failing this test means an individual cannot work in transportation until they follow DOT procedures and pass a second test. Because marijuana is still listed as a Schedule I drug at the federal level, DOT drug tests do screen for cannabis—and its presence in a result is disqualifying even if the individual resides in a state with legal cannabis.

Conclusion

Drug tests can tell you important information as an employer and help you zero in on the best candidates for a job when you use them in conjunction with a thorough background check. However, it is vital to understand the shifting landscape surrounding drug testing laws and drug usage. 

The growing availability of cannabis, both recreationally and medicinally, means that some employers need to recalculate how they interpret positive tests that show marijuana. With 37 states supplying legal medicinal marijuana and 20 legalizing recreational use, it’s a factor you can’t overlook.

Building a smart hiring process demands looking at applicants from every angle, including both their background and their potential substance abuse history. Find out how to equip your business with effective drug screening solutions to keep your hiring pipeline flowing.

Be sure. Be confident. Be fast, efficient, and consistent.
