People at high risk for heart attack or angina (chest pain) carry nitroglycerin pills like these with them at all times, to take at the first sign of trouble. You may have heard of nitroglycerin in connection with blowing things up, and yes, it is exactly the same chemical. In pill form the nitroglycerin is dispersed in binder, so unfortunately you can't blow anything up with these pills.
