'....why do you appear to be condoning those who do? You obviously had some reservations about how you would perform? - Mantra
Really? I do not recall 'condoning' working 'under the influence - of Pot, Or alcohol'.
I was saying it happens.!!.
Of course this was over ten yrs ago. Who knows now - BUT I DOUBT its any different. Do you honestly believe that every working person is straight, at all times???.
More fool you. Same for Muso - who's reply isn't worth the effort, other than this.

As to my claim to never have worked under the influence - well that was a bit of a generalisation. Having worked in many different areas of employment, in different eras, and for different employers, I'll modify my statement. When in positions of legal authority - I never worked under the influence - except for those boozey-buzz afternoons I mentioned already, which were
more than CONDONED by the senior officers. That way, they could get pissed as a fart, and no-one said Boo.!!.
My concern - in those positions - was not my ability, nor performance, .which were of a high standard

('scuse the pun).. but with being recognised as a pot smoker. In some circles that was also OK, but not in the eyes of the higher echelon hypocrits, - or the public.
I performed my duties to the best of my ability - regardless of the circumstances in which I found myself.
In fact - the people of Australia - have benefited from my application to my principles.

Also - I found study was so much more productive, and results well received , when essays eg were to be handed in for assessment. I received 'Distinctions' in all bar one of my subjects, - the last, when I got a credit.
By then - I had moved on.
I perform very well - but not under the influence of alcohol.!@!. Thats the truth.!!!!!
Believe it or not.!!!
