My mother has smoked marijuana sense she was a teenager. Probably smoked while I was in the womb, totally denies it. My school grades tell me otherwise. For the last 4 years she has had all sort's of health issues from chronic tiredness, heart palpitations, headaches, dizziness, panic attacks, depression ect. She has always been slightly overweight but she likes to exercise, especially canoe. But she would get sick when she exercised and than be out of breath. The doctors passed it off as severe depression that is genetic in the family, go figure. They gave her antidepressant medication. Finally after several severe attacks, she became brave and "ORDERD the doctor, to do an echocardiogram and an electrocardiogram of her heart.
After the test, the doctor would not let her leave the hospital and immediately made an appointment for open heart surgery the next day. She had a stint put in and is way better now. She hike's and just completed a 142 mile La Routa Miya river challenge canoe race. So if it were me, I would go in and demand not ask, to have a better heart test performed, other than a doctors uncaring ear and a cold stethoscope.
