Melissa Etheridge and Todd Rundgren were both recently busted by US Customs and Border Patrol for alleged drug possession at the US-Canada border, TMZ reports. The summer arrests (Etheridge was detained while returning to the US on Aug. 17; Rundgren was arrested Sept. 9) are just now being reported. Both occurred in North Dakota when the rockers' tour buses were stopped. A K-9 unit detected drugs in Etheridge's case and agents allegedly found marijuana oil, which Etheridge has said she uses to manage pain from cancer. The K-9 unit didn't detect drugs in Rundgren's case, but agents allegedly found two vapes and liquid THC. (More Melissa Etheridge stories.)
