The Warriors are the latest to put up their hands and admit to using pills containing a legal stimulant.
Several NRL clubs admit they administer Sudafed cold tablets to players pre-game to help stimulate them.
Sudafed contains pseudoephedrine, which up until early last year was a banned substance.
It is now legal to take, assisting with alertness.
Warrior Monty Betham says they use them, but only for night games, not for afternoon kick offs.
Betham says the odd player will take one or two if they are a bit lethargic, especially before games in Australia, given the time difference.
The Sudafed admissions come on the back of the caffeine flare up which has struck Australian sport.
Across the Tasman, Manly doctor Paul Bloomfield has confirmed some senior NRL league players use the cold tablets before big games.
Bloomfield says the practice concerns him, but he would rather supervise its use rather than having players go buy it themselves.
