The only comparison point I have for a minor with a suspected drug test is Andreea Raducan, a Romanian gymnast at the 2000 Olympics. She was 16. Long story short, she was given a cold pill with pseudoephedrine, and was stripped of her AA gold medal, but kept her team (previous competition) and other individual medal (post positive test). She competed in an additional event final after her team was notified of her positive drug test, but she did not medal there. The team doctor was suspended for I believe 2 Olympic cycles and her coaches were not, neither was she.
