The pictograph shows changes in consumption habits of the American populace for tobacco and alcohol.
In 1965 about forty two percent of the adult population smoked. This number decreased gradually over the next forty years at a rate of approximately five percent per year. The lowest percentage of smokers could be found in the year 2005, where twenty one percent of the population smoked.
Alcohol, on the other hand, has barely shown any growth or decrease, with the exception of two years; 1975 and 1985. In 1975 and 1985 the rates of alcohol consumption were ten point one percent and ten percent, respectively. This was a nearly two percent increase from the average steady rate of eight point four percent experienced in 1965, 1995, 2005 and 2008.
