My fiancee was diagnosed with endocarditis in nov 2014 and had to have open heart surgery. (He is 35 now). They replaced his aortic valve with a bovine one and had to repair his mitral valve. By the summer of 2015 he started to smoke marijuana heavily and still does up to 3 times a day. Can this complicate anything with his heart? He uses the RAW organic papers but I am very concerned that this isnt safe. Any information would be very much appreciated.
