Not in the slightest mate. Regardless if you agree with doping policy in RL at least it is taken seriously. If you consider the things that the tabloid newspapers catch players from other sports doing it is hard to believe than none of them take recreational drugs.
As everyone has given there opinion I might as well give mine. I do not see why recreational drugs results in automatic bans. Surely breaking a bus driver jaw or glassing you girlfriend is worse that taking some coke. Yet committing GBH does not have a mandatory ban in any sport. People who take the zero tolerance view to recreational drugs are very out of touch with the world we live in. If you consider the impact things like Tobacco, Alcohol and Gambling have on our sociality it is truly astonishing the difference in attitude between these evils and recreational drugs.
In the end the guy knew the rules and he broke them. But if he was in any other profession his employers would probably recognise he has a problem and try to get him help rather than sack him and prevent him from getting any other work.
