I smoke cannabis to relax my mind, not to get wasted. I recently had a pacemaker implanted to correct the blockage between the upper and lower receptors of my heart. Will continued use cause further damage to my heart or disruption in the working aspects of the pacemaker
Cannabis per se can cause various heart issues including fluctuations in blood pressure, heart rate, spasm of heart rate is too clogging of the art is causing heart attack. So by all means cannabis even social use is not advised in patients who have any kind of heart issues. You had pacemaker put for a heart block, per se cannabis will not interfere in the functioning of the pacemaker, However as a cardiologist I cannot recommend that you continue the use of cannabis, as the risk of ill effects in long run are not worth the calming effect you experience.  Try weaning yourself off. Regards Chat Doctor.
