No it's not weed. It's fruit tobacco smoked through a pipe, cooled by water.

I just got a four-pipe hookah, nearly a metre high. It's pretty awesome. Really great when you've got friends round, very enjoyable and social.

People that don't know what it is: don't be under the illusion that it is a drug. You don't get any sort of rush from it, it's just fruit-flavoured smoke.
