The U.S. Federal Drug Administration (FDA) has banned the marketing of four R J Reynolds cigarette brands because they do not meet specific safety and composition requirements. The FDA found they have changed so much over the last few years they do not resemble the original products–with higher levels of formaldehyde, menthol, sweeteners, and unclear tobacco blends. No tobacco product is "safe" even if approved for marketing.
PositiveTip: Don't start smoking, stop if you started, and help others quit. It's still good advice.
