The document discusses tobacco harm reduction through the use of low-toxicity smokeless tobacco products like Swedish snus. It summarizes evidence from Swedish population studies that finds little risk of snus leading to smoking, strengthening nicotine addiction, or weakening smokers' efforts to quit. The evidence suggests that snus use can substantially reduce tobacco-related disease risk and that some smokers who switch to snus do subsequently quit nicotine altogether. There is little scientific evidence to support arguments against tobacco harm reduction and good evidence to reject such arguments.
