Al fakher is washed, it ain't gonna do a thing. Nicotine content is almost non-existant.
Sounds like it's time you entered the amazing world of traditional nargile tobacco! Try some Desi Murli or Nakhla Zaghloul. If you really want to pack a wallop, get a hold of some tombac.
That said, the buzz really shouldn't be the point. If I feel like a need a buzz, I reach for a bottle of patron or Bombay Sapphire. Tobacco, for me at least, is about flavor, ritual, and contemplation.
