Workplace Drug Testing Laws in New Hampshire

There are no workplace drug testing laws in New Hampshire, but employers are required to follow federal employment drug testing laws when applicable.

Federal employee drug testing laws allow employers to maintain a drug-free workplace, while protecting the rights of the employees.

The Drug-Free Workplace Act of 1988. (41 U.S.C. §8101 et. seq.) targets substance abuse in the workplace. Employers must develop a drug-free workplace policy. The policy must state that controlled substances are prohibited and the actions taken against someone who violates the policy. Every employee must receive a written copy of the policy.

Other federal laws protect the employees from discrimination, defamation, wrongful discharge, and the invasion of privacy.

New Hampshire employers must familiarize themselves with these laws prior to developing workplace policies.
