That's a weird statement. I don't think I'll ever visit a cardiologist (as a patient) unless I had a suspicion of heart disease. Is it common to get checked out by specialists for no reason in your locale?
Well, I been a cannabis smoker for more than 15 years and not checked my heart once, so made sense to ensure it looked healthy. But then I live in a country (Spain) where healthcare isn't incredibly expensive, something you can do just to make sure nothing is funky wonky. I think is relatively common for people to use the healthcare we available to us, yeah.
