Buzz u live in london??

i was in tottenham yesterday and these guys were smoking a really sweet smelling weed.

ive had some in brixton before too, anyways, i love the smell, its kinda buttery, green and sweet,
but all the stuff i get around here, is so different, its the green, skunky, tree smelling weed, i REally wish i knew how to identify coz the 2 smells are so different...

anyone know what im talking about?
