i think you can still add it. i can for you if not.
i heard matches are better if you let them burn past the sulfur. i read that people who smoke fine cigars refuse to use lighters and if they do it is only with HIGHLY refined butane. apparently butane leaves some bad tastes.
hell yea, i only use Bics those other ones melt at the top if you light the bowl to long but when i roll blunts or joints it doesn't matter what kind of lighter.
