No, brewed coffee grounds and instant coffee come from the same beans, but one is a filter ingredient and the other is a dissolvable drink product. These two get mixed up all the time because they start with coffee beans and both end up in a mug. That’s where the match stops. Coffee grounds are

Yes, large caffeine doses can trigger chest pain in some people, especially with coronary disease or artery spasm. For most healthy adults, caffeine is not a usual cause of angina.
