Quite an interesting chart near the bottom of this page - https://www.cdc.gov/tobacco/quit_smoking/how_to_quit/benefits/index.htm https://www.cdc.gov/tobacco/quit_smoking/how_to_quit/benefit... - doesn't quantify everything, unfortunately, but yeah even after a year the "risk of heart attack drops sharply".
