Washington Drug Testing Laws

Under Washington law, there are few restrictions on employers who implement a drug-free workplace policy. Washington has passed statutes allowing the use of Medical Marijuana and Recreational Marijuana. However, courts have recognized that employers are under no obligation to accommodate the use of Marijuana.

Marijuana in Washington: Both recreational and medical marijuana use is legal in Washington. While employers have the right to establish a drug-free workplace and are not mandated to accommodate the use of medical marijuana, they should be cautious of discrimination issues.
