The Premier Soccer League will this year introduce anti-doping tests for all players.

Speaking at a workshop organised by the PSL for club doctors, Zifa head of medical committee Dr Edward Chagonda said players should be in the know of drugs and substances that are not allowed in anti-doping and sports medicine.

“The most important thing is for the players to know what is at law and what is not. So before using a prescription, they should either go to the FIFA website and check on banned substances and drugs or consult their team doctor. This year it’s going to be stiffer because we are going to carry out random tests,” said Dr Chagonda.

Some of the Premier League players who smoke marijuana (mbanje) are likely to fall short on the tests.
