Via National Law Review:
In May 2019, the city of New York banned employers from testing job candidates for cannabis, specifically THC. The measure was put in place on May 10, 2019.
There are certain carved-out exceptions to this new city law:
The new law, however, contains an important exception for certain healthcare workers. Specifically, the law does not apply to any individuals applying for work in any position requiring the supervision or care of children, medical patients, or vulnerable persons as defined by Section 488(15) of the New York Social Services Law. The law further excludes employees in positions that “significantly impact the health or safety of employees or members of the public.” (Source: https://www.natlawreview.com/article/new-york-city-ban-pre-employment-drug-testing-won-t-apply-to-most-healthcare-workers)
The New York City Commission on Human Rights will now draw up the rules for putting the full law into action.
