But, but, but...
Sure, it can help with tiredness and focus, but is it worth it? Not in my book. I've smoked my share, believe me, and one thing I absolutely HATE is trying to work (for other people) stoned. For one thing, my time-sense elooongaaateees, and work can seem like aaagggeeesss...
For another, why on Earth would I want to make an enjoyable experience into the Hell On Earth it becomes, when I have to use so much extra energy to make sure I don't screw up, simply from my attention wandering at the wrong time, or because I forgot something (easy to do, when you are stoned)?
I say keep the pot at home, and go to work straight.
