one time in an attemt to get as high as i possibly could off of one hit i brewed up a 3 litre bucket toke, it was almost brown cause i sprinkeld a bit of blonde hash and some crystal from my buddys grinder, it was crazy when i closed my eyes i started to get the spins and couldnt do it any longer than like 5 seconds.....never again...... i probably damaged a few brain cells with that toke
