he isnt smoking while working .
HOWEVER ,the safety aspect of this job,this dangerous job needs concentration , means i cant trust a dope smoker . ive now woken up at 4 a.m. worrying , knowing theres 2nd floor ladderwork ahead tomorrow on a big job ,and plenty more coming ahead , id be foolish to allow him to do it
Indeed safety is very important. Let's not demonise dope because of the illegality though.
1. A man has a few beers one evening. Climbs ladder next day.
2. A man has a few joints one evening. Climbs ladder next day.
My own experiences point to scenario 2 being the safer.
So long as someone wasn't an habitual, heavy smoker and wasn't deep into an unmanageable lifestyle, I would have no more problem employing a moderate, occasional smoker than I would anyone else.
I even knew a couple of coppers who smoked sometimes and, believe it or not, a clergyman
