I recently had a stent inserted in LAD artery and have totally quit smoking after 47 years of 1/2 pack a day. I am on blood pressure meds, blood thinners now, and lipitore, and janumet for sugar(borderline), not overweight . I smoke marijuana recreationally , a few joints on weekend. Unlike cigarettes , how will this affect my stent and arteries. I was a heavy smoker all my life of marijuana and the rest of my heart and arteries are good. Do you think occasional weekend usage will affect the stent and that area?
