There are plenty of readily available substances which are tbf. A lot depends on how much of the substance was found in his system. We had a bloke here back in the 90s who got done for elevated caffeine, was an Olympic athlete. He said he drank a lot of coffee, but the amount in his blood suggested he'd have had to have drunk like 140 cups of full strength coffee in the 12 hours before his test, or something like that.
There have been a number of athletes done through ingesting widely available substances in the past. It always strikes me as tough to some extent, but it gets back to being responsible for what you take, like the Aussie swimmer who got done at the WCs recently. She says she didn't knowingly take it, but apparently she didn't check what was in the supplement she was taking. With Shaw, if it comes back that there's some minimal trace of the drug consistent with taking cough syrup, then I fell sorry for him. But if there's enough of it to knock over a horse, then its suggestive he's been bathing in cough syrup for quite some time, and if that's the case then the ban is jokingly short.
In any event, quality young player.
Edit: How's the BCCI just accepting what he said straight up and giving him a minimal ban? Two other blokes done too. There seems to be a lot of inadvertent ingestion going on here. Blokes need to watch what they eat ffs. Also, is anyone across where the BCCI anti-doping regime sits compared with WADA sanctions?
