Low-Yield Cigarettes and Cigarette-Like Products

Cigarette manufacturers have developed cigarettes that deliver less tar or nicotine in standardized machine measurements.^1,2 Brands with machine-measured lower tar levels (i.e., low-yield cigarettes) have been marketed as reduced-risk cigarettes, using terms such as "light" and "ultra-light."¹ The tobacco industry recently introduced "cigarette-like" products, such as Eclipseฎ and Advance.™ ³ Low-yield cigarettes and cigarette-like products are examples of a classification of products referred to as "potentially reduced-exposure products" or PREPs.²
 

• Tar refers to the total particulate matter in smoke, excluding water and alkaloid compounds such as nicotine, as measured by using a standardized protocol on a smoking machine.⁴
   
• Cigarette brands that yield approximately 1–6 mg of tar are generally called "ultra-light." Those with approximately 6–15 mg of tar are called "light," and brands yielding more than 15 mg tar are called "regular" or "full flavor."¹
   
• Ventilated cigarette filters are the major innovation behind low-yield cigarettes. Filter vents dilute smoke with air and reduce standard yields of tar, nicotine, and carbon monoxide.¹ Currently, 98% of all cigarettes are filtered.⁵
   
• During 1968–1998, the average yield of tar in cigarettes decreased 44%. The average nicotine yield decreased 34%.⁴
   
• Many smokers block the vents or compensate when smoking low-yield cigarettes, thus inhaling more tar and nicotine than measured by machines.⁶  Smokers may get as much tar and nicotine from cigarettes with low-yield ratings as those with higher yields.^1,4
   

• Use of low-tar products increases dramatically as age, education level, and income level increase, and is higher among women than men.¹
   
• Many smokers consider smoking low-yield cigarettes, menthol cigarettes, or additive-free cigarettes to be safer than smoking regular cigarettes.^1,2
   
• Many smokers of low-tar cigarettes may have switched to such brands instead of quitting.⁶ Smokers may be misled by the implied promise of reduced toxicity underlying the marketing of such brands.⁶
   

• The risk for lung cancer is only slightly lower with low tar cigarettes, and reduced tar levels have little, if any, effect on other lung diseases or heart disease.⁶
   
• Existing research does not support recommending that smokers switch to low-yield cigarette brands.¹ There is no convincing evidence that changes in cigarette design have resulted in an important decrease in the diseases caused by cigarettes.¹
