I think it is an invitation, NOT pointing a gun at anyone's head and forcing them to come.
People who want to join in, may join in, people who do not want to join in, fair enough.
Its a free world, and everybody has a point of view and is more than welcome to address it.
There are a lot of other harmful things which we live in, day in day out, say all the pollution we inhale when we are driving or standing at a signal, coming out of the not so eco friendly cars, rickshaws, busses, trucks. Why dont we take into account those hazards, even if we have, we arent able to stop it.
Im not in favour of forcing anyone to go to the meet, but let the chaps do what they want to do, they are not forcing you, Sheesha is bad for health, agreed and should not be made into a habit.
Anyone who contradicts my statement please feel free, im just giving my opinion, as to how i see it, not here to argue with anyone 
@ fastoriel, goodluck for the meet bro, eat/drink healthy, stay healthy
