The World Anti-Doping Agency has published the list of banned substances for athletes which will come into force in 2017.
Tennis player Maria Sharapova is serving a two-year ban after testing positive for meldonium, which was added to the list in January 2016.
Wada president Craig Reedie said: “There can be no tolerance for people who intentionally break the rules.”
The updated list comes into force on 1 January 2017.
It covers substances and methods banned in and out of competition, and which substances are banned in different sports.
Reedie said “athletes and their entourage” have “ample time to familiarise themselves” with the updated list.
“All athletes around the world are held to these standards,” he said.
Wada said in April that scientists were unsure how long meldonium stayed in an athlete’s system.
It also suggested athletes who tested positive before 1 March could avoid bans, provided they had stopped taking it before 1 January.
Sharapova, 29, tested positive for meldonium at the Australian Open in January 2016 and an out-of-competition test on 2 February.
The Russian said she had been taking meldonium since 2006 for health reasons and was unaware it had been added to the banned list as she knew it only by the name mildronate.
