Thirty‐nine canned soft drinks obtained from New York (NY) State and from Ontario in 1986 were analyzed for caffeine. The major brands of cola drinks from either location differed little in caffeine concentration, with mean values of 92.5 μg/mL for NY State and 86.5 μg/mL for Ontario. However, different can volumes contributed toward the difference in caffeine content per can of cola beverages obtained in NY State and Ontario. The mean caffeine values for the “regular colas” were 34.3 and 21.5 mg/can (concentration range: 2.3–133.4 μg/mL and 0.1–104.9 μg/mL) for the NY State and Ontario products, respectively. The range of caffeine content for all products was from 0.8 to 50.8 mg/can for the NY State colas and from 0.03 to 29.4 mg/can for the Ontario products. Comparison with earlier reports (for USA from 1979:47.3 mg/can; for Ontario from 1976: 40 mg/can) indicated a general decrease in the amount of caffeine in all types of cola beverages in the last 7 years.
