i'm with brad on this one, from everything i've heard i've come to believe that tar is only produced when you don't smoke correctly and burn your shisha.
as far as convincing your parents it's ok. well you're 18, maybe just keep it in your car? i can't smoke in my house either but the shed has become my second room
if anything maybe you can convince them just to let you keep it and smoke it away from the house
