At the 1998 Olympics in Nagano, Japan, officials stripped the Canadian snowboarder Ross Rebagliati of his gold medal after he tested positive for THC. Rebagliati contested the ruling. He said he had quit smoking pot to train for the games, but had inhaled secondhand smoke at snowboarder parties.
The appeal worked. After 36 hours Rebagliati’s medal was restored. He flew to California and in an appearance on the Tonight Show with Jay Lenoacknowledged past marijuana use. The next time he tried to enter the US, Rebagliati learned he was barred from the country for life, according to his immigration lawyer Leonard Saunders.
