However, more and more states and localities are either enacting marijuana laws with express employment protections or resolving court cases in favor of marijuana users. Yet, more than a decade ago, the California Supreme Court held in Ross v. RagingWire Telecomm., Inc., that employers have the right to reject an applicant who tests positive for medical marijuana. Since that time, while California employers have enjoyed some comfort in the ability to enforce their workplace substance abuse policies, lawmakers have been making efforts to amend state law to provide more protections to marijuana users.
