Yeah you would think that would be all it would affect,, But not so, when you smoke marijuana ,,, not just cigs,,, it makes the heart work harder, it increases the heart rate and Lowers the blood pressure and by both of those happening can cause irregular heart rhythms and people that are already having heart problems can have a heart attack,, and that did not just come from My knowledge on that subject ,,, I double checked ,, Heart disease is the # 1 killer of women,, my mom died from a heart attack after her chemo weakened all her organs,, my grandma had a heart attack the day my mom died. So I have done a little reading on it cuz I am pretty sure that is how I am going to go. Sucks,, but that's the way it goes,, well no I have a good chance of getting cancer too,, my dad and my mom died last year from that horrible disease. So No I would not take chances and smoke anything,, when it comes to the heart,, you don't want to mess around .. :nono:
