Docs, could a heart patient smoke weed and still be okay?

Yes, they could: but would be better off not smoking, but getting an inhaler. They make the equivalent of electronic cigarettes for use with marijuana, where there is a heating element that volatilizes the THC from the plant, without producing smoke, carbon monoxide and other harmful elements. However, marijuana increases heart rate, which is often not good for people with underlying heart disease. Talk to your MD
