In this industry, removing a question mark can mean a great deal — especially when it’s removed from a government website. Earlier this week, the National Institute on Drug Abuse switched the title of its website page from “Is Marijuana Medicine?” to “Marijuana as Medicine.” And that wasn’t the only change.

Nearly every section of the site, which was last revised in July 2015, has minor changes.These revisions may seem inconsequential, but for the cannabis industry and patients who use marijuana for medicinal purposes, they appear significant.
