Shares of pot companies were trading higher on Thursday as the U.S. Senate Banking Committee prepares to discuss the SAFE Banking Act, a crucial legislation that would make it easier for the cannabis industry to access banking services, Reuters reported. If the bill advances through the committee stage, it would be voted by the Senate for the first time. The bill has been passed by the House of Representatives seven times in the past. Industry insiders are cautiously optimistic that the bill, which has bipartisan support, will be signed into law this time.
