Any problems flying with a wax pen (that looks just like ejuice) through taiwan, thailand, south korea, and japan? anybodies experiences doing so? obviously know herb is a big no-no, wondering how safe or unsafe carrying a wax pen would be. also theres a THC inhaler that looks just like a regular inhaler, no label or anything. maybe this is a safer route or would one be questioned for a script for the inhaler?
