If marijuana was legal for adults in California, would more people show up at work high? And how would that change the definition of a “smoke break” during work hours?

That’s the latest issue facing proponents of Proposition 19, the ballot measure that would make marijuana legal for adults in California.

Voters will have a chance in November to decide whether to legalize marijuana for recreational purposes for adults over 21 but the political debate over the controversial issue has been heating up for quite some time. The latest argument against the ballot measure is that given the legal freedom to smoke pot, people will be high at work.

The California Chamber of Commerce on Thursday released a legal analysis that claims Proposition 19 would lead to more workplace accidents by forcing employers to let workers smoke pot on the job. The analysis by the non-profit group also challenges the proposed law by claiming it would make California companies ineligible for federal contracts because employers could not guarantee a drug-free workplace.

A ridiculous argument for obvious reasons. Along with a ban on alcohol use at work, individual employers will enforce the same with marijuana. Problem solved…no study necessary, the advice is free.
