An equally important issue is the use of caffeine by the average active teenager or adult. Caffeine’s widespread use was demonstrated in a recent survey by the Canadian Centre for Drug Free Sport. The survey found that 27% of Canadian youths (11-18 years old) had used a caffeine-containing substance in the previous year for the specific purpose of enhancing athletic performance. Does caffeine act as a “gateway” drug for the young who then use dangerous substances? For the average, active teenager or adult who is exercising with the goals of enjoyment and self-improvement, using caffeine defeats these purposes. Proper training and nutritional habits are more sensible and productive approaches.
