Summary of differences between federal and state regulations
Unemployment compensation
New Hampshire’s unemployment compensation law provides that an employee who has been discharged for intoxication or for use of a controlled drug, to the degree that it seriously hampered or interfered with their work, is not eligible for benefits.
Workers’ compensation
New Hampshire’s workers’ compensation law provides that an employer is not liable for any injury to a worker which is caused in whole or in part by the intoxication (from drugs or alcohol) of the employee. The intoxication defense does not apply if the employer knew that the employee was intoxicated.
Deduction for medical exams
Employers may not deduct the cost of medical exams or records required by the employer from the employee’s wages.

Under the Improve Tracking of Workplace Injuries and Illnesses final rule, the Occupational Safety and Health Administration (OSHA) prohibits employers from using drug testing, or the threat of drug testing, to retaliate against an employee for reporting an injury or illness.
Employers may conduct post-incident drug testing if there is a reasonable possibility that employee drug use could have contributed to the reported injury or illness.
