The impact of taxation reduction on smoking in youth between 1990 and 1999: results from a reconstructed cohort analysis of the Canadian Community Health Surveys.

Birkett NJ - PLoS ONE (2014)

Bottom Line: There was a strong increase in smoking in youth in the years following the reduction in tobacco taxes.The number of excess daily smokers for people born between 1977 and 1985 that can be linked to the taxation reduction is about 190,000.There is strong evidence that reduction of tobacco taxes to combat smuggling had an adverse impact on smoking rates in youth.

ABSTRACT

Background: Increases in taxation can contribute to smoking control. In the early 1990's, tobacco smuggling rates in Canada increased dramatically. Governments responded with a substantial reduction in taxes on tobacco products. This study examines the impact of these tax changes on smoking in youth in Canada.

Methods: Data on smoking from three consecutive cycles of the Canadian Community Health Surveys were combined and analyzed using a reconstructed cohort approach. Age, sex and calendar year specific rates of smoking experimentation and the onset of daily smoking were estimated for youth. Estimates apply to the entire Canadian population.

Results: There was a strong increase in smoking in youth in the years following the reduction in tobacco taxes. The increase was stronger in women. The rates returned to pre-1990 rates by about 2002. The number of excess daily smokers for people born between 1977 and 1985 that can be linked to the taxation reduction is about 190,000.

Interpretation: There is strong evidence that reduction of tobacco taxes to combat smuggling had an adverse impact on smoking rates in youth.

Rates of Onset of Daily Smoking.Rates of onset of daily smoking from 1980 to 2003, ages 12–24. Blue colors indicate low rates; red colors indicate high rates. Temporal trends are shown when the color changes along vertical lines through the graphs. (A) Males and females combined. (B) Males only (C) Females only.

pone-0093412-g002: Rates of Onset of Daily Smoking.Rates of onset of daily smoking from 1980 to 2003, ages 12–24. Blue colors indicate low rates; red colors indicate high rates. Temporal trends are shown when the color changes along vertical lines through the graphs. (A) Males and females combined. (B) Males only (C) Females only.

Mentions: Figure 2 shows similar contour plots for the onset of daily smoking. The onset of daily smoking is again largely a phenomenon of teenagers. There are two peaks for the onset of daily smoking: age 16 and 18. Conversion to daily smoking had been declining in the 1980s as shown by the decrease in the prominence of the red regions between 1985 and 1990. However, starting around 1993, there was a rapid increase in the rate that largely persisted to the end of the study time frame in 2003. Stratifying by sex reveals general similar patterns. The increase in conversion rates for males was more pronounced in 18 year olds. However, for females, the increase was more apparent in 16 year olds.
