What the hell are you talking about? Did you really think people soaked tobacco in tar and smoked it?
In regards to the actual question:
No, the length of your stem doesn't mean much in this case. It seems like you may be over packing or using too much heat. Some shisha can't recover from being burnt at all and need to be replaced or have the burnt picked out and then flipped to keep smoking smooth.
As it has been asked, what kind of bowl and coal?
