Barry Grissom, a former U.S. Attorney for the District of Kansas who was practicing at Polsinelli until earlier this year, has joined Electrum Partners, an advisory services firm concentrating on the cannabis industry.

Grissom said he was recruited to Electrum by its chairman, Leslie Bocskor, who was seeking someone to help with public policy issues. He will be senior vice president of global policy and corporate counsel at the Las Vegas-based company, which helps cannabis-related ventures secure financing and advises them on government relations, marketing, distribution and other issues.
