Rhode Island drug testing laws for employers
Rhode Island has strict rules for any employer that tests. You may test a current employee only on documented reasonable grounds, never at random (outside federal mandates and a few listed industries), and a first positive leads to referral for help, not firing. Adult-use cannabis is legal and off-duty use is protected for most jobs.
Have a whole roster to keep current every month? DOT fleets: Pact's monthly DOT program, $25 a driver a month ($99 minimum), or $19 a month for an owner-operator. Nursing homes, hospice and home care: staff credential tracking, $10 a staff member a month ($250 minimum). First month free.
The state law
- You may test a current employee only if you have reasonable grounds, based on specific contemporaneous documented observations of the worker's appearance, behavior or speech, to believe they may be impaired (R.I. Gen. Laws 28-6.5-1(a)(1)).
- The employee gives the sample in private, with no one present (R.I. Gen. Laws 28-6.5-1(a)(2)).
- You may not fire an employee for a positive test; you must refer them to a licensed substance abuse professional, though you may fire someone whose testing shows continued use despite treatment (R.I. Gen. Laws 28-6.5-1(a)(3)).
- Positives must be confirmed by a federally certified lab using GC/MS or an equally accurate method (R.I. Gen. Laws 28-6.5-1(a)(4)).
- You must offer, at your expense, a retest by an independent facility, and give the employee a fair chance to explain or rebut the result (R.I. Gen. Laws 28-6.5-1(a)(5)-(6)).
- You must have a written drug abuse prevention policy and keep results confidential (R.I. Gen. Laws 28-6.5-1(a)(7)-(8)).
- Testing outside these rules is a misdemeanor with fines up to $1,000 or up to a year in jail, and workers can sue for punitive damages and attorney's fees (R.I. Gen. Laws 28-6.5-1(b)-(c)).
- Federally mandated DOT driver testing is not affected (R.I. Gen. Laws 28-6.5-1(e)(1)).
Testing applicants
- You may test a job applicant only after a job offer conditioned on a negative result (R.I. Gen. Laws 28-6.5-2(a)(1)).
- The applicant gives the sample in private, and positives must be confirmed by a federally certified lab by GC/MS or an equally accurate method (R.I. Gen. Laws 28-6.5-2(a)(2)-(3)).
Random testing
- We found no provision allowing random testing of employees; employee tests need documented reasonable grounds (R.I. Gen. Laws 28-6.5-1(a)(1)).
- Exceptions cover federally mandated DOT testing, federally mandated testing in public utilities and mass transit, and highway maintenance employers testing under 49 CFR Part 40 (R.I. Gen. Laws 28-6.5-1(e)).
Marijuana (recreational)
- You may not fire or discipline an employee solely for private, lawful cannabis use outside the workplace if they are not working while impaired, unless a union contract bans it (R.I. Gen. Laws 21-28.11-29(d)).
- Federal contractors and employers that would lose a federal benefit are exempt from that protection (R.I. Gen. Laws 21-28.11-29(d)(1)).
- For hazardous or safety jobs, such as heavy equipment, commercial vehicles, school buses, first responders and surgical staff, you may ban use within 24 hours before a shift (R.I. Gen. Laws 21-28.11-29(d)(2)).
- You do not have to allow cannabis at work, including remote work, and you may act on violations of a workplace drug policy or working while impaired (R.I. Gen. Laws 21-28.11-29(d)-(e)).
- You may not refuse to hire or penalize someone solely for being a medical cannabis cardholder, though you may act on use, possession or impairment at work (R.I. Gen. Laws 21-28.6-4(e)).
