The use of nicotine by athletes has not been thoroughly examined. A recent study found that 1 in 5 athletes, from a range of 90 different sports, tested positive for nicotine in-competition. Positivity rates were lower in endurance sports than power-based ones, and lower in individual sports than team sports. These findings suggest that WADA could further investigate nicotine use within elite athletes.
