Something that I've never really got my head around is judging how high i am, because usually by the time i stop to think about it i'm completely incoherent. However my go to trip music is Pink Floyd (with iTunes visualiser turned on) so i can usually get a rough idea of how far along i am based on how awesome Floyd are.

i'd be interested to know if you have a way of measuring your highness, a particular song you always listen to, or merely what you think of Floyd, the most iconic stoner music ever conveniently available on YouTube.

cheers
