In the summer of 91 I was a student in Sheffield. I went to stay with my girlfriend in Newcastle over the summer holidays and unknown to me our dealer stayed in my room in sheff and was still there when i returned. I was a bit pissed off I didn't know about it as he was there when I returned to sheff.
He was a sound guy and as an apology gave me his dregs which included an ounce of really shit speed and a sheet of 'traveller' acid that he'd picked up god knows where.
The acid sheet was basically just an A5 sheet of cardboard (white on one side / fluorescent orange the other) that he told me to cut into 1cm squares.
Those squares were later quartered into manageable doses
but I'd like to apologise now to anyone who bought a 1cm square of white and orange acid in sheff in the early 90s. You might be coming down about now.
