We are in the middle of another battle in access to harm reduction products. But, unlike drivers and passengers wearing seat belts, cigarette smokers are met with adversity, hostility and outright prohibitions by federal agencies and lawmakers. E-cigarettes, the most popular form of tobacco harm reduction, have helped millions of American adults quit smoking.

Yet, despite this, there are national campaigns to stop the use of e-cigarettes and four states have banned the sale of flavored e-cigarettes.
