If you call this number and ask about tobacco Harm Reduction they transfer you to Public Affairs.Telephone: 240-276-8853
If you talk to Public Affairs they tell you to read the recent Surgeon General's report about tobacco use on their website...
http://www.surgeongeneral.gov/library/reports/preventing-youth-tobacco-use/full-report.pdf
When I click the link on their website I can not get the entire PDF to load in either Internet Explorer or Chrome.
But I am told by Public Affairs that there is a section of the report that discusses other tobacco products such as "smokeless" and "spitless".
