is a m80 a quarter stick of dynamite
M-80 (explosive) Contrary to urban legend, an M-80 that contains 3,000Â mg of powder is not equivalent to a quarter-stick of dynamite. Dynamite generally contains a stable nitroglycerin based high explosive, whereas M-80s or any other kind of firecracker contains a low explosive powder, like flash powder or black powder.[6] Some illicits, however, contain(ed), or were reported[by whom?] to contain, small amounts of picric acid (similar to TNT), for greater effect.[citation needed]
