hey so I just went down to the local headshop and bought a "smoking since 1879" automatic roller for regular sized papes. I've bought one before, so Im almost certain I am using the proper technique. but everytime I insert the paper and roll the gum sticks itself not even close to the rolled log of weed. what am I doing wrong? how can I fix this problem. So mad right now, b/c a part of me thinks the guy at the headshop sold me a broken machine :s
