Yeah but pot probably helps him emotionally. I have no idea why this country won't join the 21st century. Oh wait... it's about money. Never mind. Since it's a plant, they can't think of a way to tax it without controlling it in some way. I smoke a bit every night before I go to bed and I am the most productive developer at my company. So, Rolando doing it on his time off is a non-issue to me from a personal standpoint. I also abruptly stopped for 6 weeks when I went to the UK to work last year but it didn't affect me in any way. Yes, you can get as mentally attached to it as many of us are attached to Alabama football but you cannot become physically addicted to it like one would with narcotics or alcohol. Ok... rant over.
As much as I believe in legalizing it, unfortunately, if you're going to work at a place that doesn't allow it, you can't do it. Simple as that. If this is something that helps him relax and stay out of trouble, he should consider using normal medical solutions until the rest of the world loses its prejudice and catches up. Otherwise, there's no excuse for it. You simply have a choice ... play football in the NFL and get tested every so often or find some other job out there where you don't get tested. It's pretty simple.
