Just scanned the articles, but they sounded a little hysterical to me,
and ignoring the problem WADA has to deal with.
EG. Slate The alcohol amounts are set by different jurisdictions, not
covered by WADA. Why is that idiotic? As for why the difference,
maybe with 2/10's you don't get an advantage (eg calming of nerves) in
billiards, while 3/10's in boating corresponds to impairment.
Different problems, different amounts. Weak thinking and writing.
As for Rushall and colleague, it sounds like grandstanding on details
to me. Steroids don't work? Maye for some untrained people, but how
is that relevant to our problem? The label for steroids in the WADA
list is a big issue?
