PORTLAND, Ore. (AP) -- Nike Inc. is being blasted for replacing its signature "Just Do It" slogan on some T-shirts with the phrases "Dope," ''Get High" and "Ride Pipe." The shoe and athletic apparel company, based in Beaverton, Ore., said the terms are part of the lingo used by the skaters, snowboarders and participants in other extreme sports that it's trying to target with the shirts. But critics say the slogans endorse drug use. Boston's mayor has asked Nike to remove a display of the shirts. And an Oregon antidrug group condemned them in a letter sent to 1,500 people -- including some at The White House Office of National Drug Control Policy -- urging them to let Nike know they disapprove of the slogans.
