Hmmmm, not sure I get you...are we talking about the Iranian city or the weed what makes your head go all funny?
I have never visited Iran.
I have smoked hash a few times when I was younger. The first time being in Irvine Precinct in 1993, obviously I coughed half my innards up. Tried it a handful of times after that though, to see what the fuss was about.
It done nothing for me, and I take great pride in refusing it when mates offer me some.
Smoking is a filthy habit and one which I'm glad I don't have!
