My husband recently had a stent put in his RAC. He s working really hard to quit smoking. In fact, he hasn t smoked at all, but he has taken to using 3-4 SNUS a day (snuff packets). I m sure he will quit these soon too, but in the mean time we d like to know if smokeless tobacco contributes to atherosclerosis? We are certainly aware of the dangers of mouth, throat, and GI cancers and hypertension, but our direct question is concerning the arteries.
