My friends smoke weed and I have always wanted to know what it was like, I have a congenital heart disease called shone's syndrome, (it is rare I don't know if you guys will know what it is). I want to know if my heart murmur will give me any chance of dying or risk of health. I play tennis just fine and don't have trouble doing day to day things, but I am still scared because of my heart condition. Will weed effect me more because of my heart condition?
