I honestly reckon there must be drugs in the WIND today, every thread has gone bonkers.

Kizzy... the point was that she knows people with complicated jobs who smoke weed (evenings and weekends I assume, not in the office ), and smoking weed doesn't affect their ability to do their job during the day, thus anecdotally demonstrating that smoking weed doesn't necessarily damage people psychologically or reduce their brain function.

It has nothing to do with the job itself somehow reducing the side effects of the drug . No one said that, anywhere. I assume it was the example used because it's the example she knows of people who need to "use their brains a lot". Likewise, I could use the example of having known a lot of students who smoked all through University and still came out with good / 1st class degrees.
