TOKYO (Reuters) - The rules on the use of cannabis by athletes should be reviewed, World Athletics President Sebastian Coe said on Tuesday, after rising track and field star Sha'Carri Richardson will miss the Tokyo Games following a positive test for the substance.

The sprinter, aiming to become the first American in 25 years to win the women's 100m Olympic title after Marion Jones was stripped of the 2000 gold, tested positive for cannabis last month at the U.S. Olympic Track & Field trials after streaking to victory in the 100m.
