BOSTON (AP) — Changing marijuana laws aren't necessarily making weed more welcome in the workplace.

For now, many employers seem to be sticking with their drug testing and personal conduct policies, even in states where recreational marijuana use is now permitted. Others are keeping a close eye on the still evolving legal, regulatory and political environment.

Voters in California, Massachusetts, Maine and Nevada voted Nov. 8 to approve the use of recreational marijuana. Four other states already allow recreational pot and more than two dozen have medical marijuana programs.

All of the laws allow employers to continue testing workers for marijuana or keeping zero-tolerance policies in place.

Some advocates for reform of cannabis laws say employers should rethink zero tolerance policies and treat off-the-job use of marijuana as it would alcohol.
