I have tricuspid valve artesia, and have a pacemaker. i have been smoking marijuana for 3 years, what are my health risk.

No one knows.: You do have some risk from the atresia of the valve, and recently a new.study suggests that there is an increased risk of myocardial infarction (heart attacks) in people who smoke marijuana regularly. Since that study has not yet been duplicated, I don't know what to make of it, but it is something to consider. You might consider cutting back on the marijuana some until the issue is sorted out.
