<p>Over the last decade, doping has been in the news as many athletes have landed in trouble after testing positive for banned substances. And ahead of the upcoming Commonwealth Games, Indian sprinter Dhanalaksmi, who was part of the 4x100m relay team, and Aishwarya Babu, the triple-jump national record holder, failed their dope tests.

Psychoactive drugs are substances that affect how the brain works and cause changes in mood, awareness, thoughts, feelings and behaviour.
