Gavin Henson believes Warren Gatland's recent comments that he had suspicions about a Wales international rugby player taking performance-enhancing drugs merited a proper investigation from the Welsh Rugby Union.
Gatland told Off The Ball that players making jokes about a teammate during his time as Wales head coach led him to suspect he may have been taking drugs.
The WRU subsequently spoke with Gatland and said they were "satisfied with the clarity he provided" regarding the matter.
"I've been in an environment where the drug testers come in and there's one or two boys who run out," Henson told Wales Online.
"That's happened at professional level.
"How it is acceptable, I don't know, but as a player you can't do anything about it.
"Yeh, of course it made me angry. Boys are cheating and those kind of things give you such an advantage. There are boys who have had careers on the back of taking stuff that has cost other players international places, or even club team places, which is really lucrative.
"For me, I feel the rule that should be in place is if you get caught taking drugs it should be a jail sentence, because you are stealing a living. You are taking money from someone else. One or two boys were quite open and honest about it but there's no proof.
"There was always changing room talk but unless you are a doctor or something you can't prove it.
"For a coach to say what Gatland did, I felt like there should be an investigation, but there we go."
