yeah i would avoid post it notes if at all possible... i'd really avoid any paper that isn't specificly rolling paper if possible... i remember when i was around 10 or so, i took a lot of dried up leaves, crumbled them upa nd rolled 'cigarettes' with note book paper... aside fromt he shitty taste of the leaves, the paper was harsh and burned the hell out of my throat, i can't imagine it would be much diffrent or better after 11 years..
