India's two-time Olympic medal-winning javelin thrower Neeraj Chopra said doping is a big problem among Indian athletes. Talking to The Lallantop, Neeraj said, "They think...only doping can get them performance...but that's not the truth. It's their hard work, self-belief and proper guidance from coach that will take them forward." He added, "The mindset of our athletes needs to be changed."
