West Virginia drug testing laws for employers

West Virginia has no general drug testing statute for private employers, but its top court limits testing of current employees to reasonable suspicion or safety-related jobs. Medical cannabis patients are protected from action based only on their certification. Contractors on public construction contracts over $100,000 must run a full drug-free workplace program with testing.

The state law

We found no West Virginia statute that sets general drug testing rules for private employers (no statute found).
Employers of certified miners must run a program with a pre-employment 10-panel urine test, random testing, and annual program review (W. Va. Code 22A-1A-1(a)).
Mine employers must report a certified miner's positive test or refusal to the state within 7 days (W. Va. Code 22A-1A-1(d)).

Testing applicants

West Virginia's top court upheld a private employer's drug test of a new hire after a job offer and before work started (Baughman v. Wal-Mart Stores, Inc., W. Va. No. 31312, 2003).
The court said fair practices, such as giving results and a chance to confirm or challenge them, count when judging a testing policy (Baughman v. Wal-Mart Stores, Inc., W. Va. No. 31312, 2003).
You may not refuse to hire someone solely because they are certified to use medical cannabis (W. Va. Code 16A-15-4(b)(1)).

Random testing

Testing current employees goes against public policy unless you have a reasonable, good-faith suspicion of drug use or the job involves public safety or the safety of others (Twigg v. Hercules Corp., 1990, as quoted in Baughman v. Wal-Mart Stores, Inc., W. Va. No. 31312, 2003).
That means random testing should be limited to safety-sensitive jobs (Twigg v. Hercules Corp., 1990, as quoted in Baughman v. Wal-Mart Stores, Inc., W. Va. No. 31312, 2003).
Public construction contractors must randomly test at least 10% of safety-sensitive workers each year (W. Va. Code 21-1D-5(1)(B)).

Marijuana (medical only)

You may not fire, threaten, refuse to hire or otherwise discriminate against an employee solely because they are certified to use medical cannabis (W. Va. Code 16A-15-4(b)(1)).
You do not have to allow medical cannabis use on your property, and you may discipline someone for being under the influence at work (W. Va. Code 16A-15-4(b)(2)).
You do not have to do anything that would break federal law (W. Va. Code 16A-15-4(b)(3)).
A patient may not work at heights or in confined spaces, including mining, while under the influence of medical cannabis (W. Va. Code 16A-5-10(2)).
A patient may not operate vehicles, heavy machinery, high-voltage equipment or permit-required chemicals with more than 3 ng/ml of active THC in their blood (W. Va. Code 16A-5-10(1)).
You may bar a patient under the influence from life-threatening tasks or duties that could create a public health or safety risk (W. Va. Code 16A-5-10(3)-(4)).
Adult-use marijuana is not legal in West Virginia, so we found no off-duty use protection for non-patients (no statute found).

Also good to know

On public construction contracts over $100,000, the contractor and subcontractors must have a written drug-free workplace policy and give a sworn statement that they keep one (W. Va. Code 21-1D-2(b), 21-1D-4).
That policy must include pre-employment, post-accident and reasonable-cause testing with at least a 9-panel urine screen at an HHS-certified lab and MRO review of positives (W. Va. Code 21-1D-2(d), 21-1D-5).
Contractors must give employees 2 hours of drug-free workplace education within 6 weeks of hire and supervisors 2 hours of training every year (W. Va. Code 21-1D-5(12)-(13)).
Contractors must file a certified report with test counts at least once a year or at project end, and violations can bring fines and a one-year bidding ban (W. Va. Code 21-1D-7b, 21-1D-8).
A worker fired for failing or refusing a random test in a safety-sensitive job, or for violating your drug-free workplace program, can be denied unemployment benefits for gross misconduct (W. Va. Code 21A-6-3(2)).
