My husband has 2 arteries with 75-80% blockage, one was just stented. he is 65, normal weight, normal blood panel, no family history and had no symptoms. Oh, exercises 5x week at gym and 20 minutes cardio daily. There was excessive plaque/ calcium buildup in his arteries. his diet is pretty clean, lots of fruits and veggies daily, lean meat 2-3 x a week, drinks beer daily 4-5....and smokes marijuana almost daily, once a day early evening. Question, is the pot smoking less dangerous to your heart than cigarette smoking??? Thanks
