Hey
In Pakistan, we get copious amounts of hash, but there is nary any weed to speak of. Anyways, when rolling a CJ (or a joint in a cigarette) pull the filter out with your teeth after your finish packing it - then tear 60 odd percent of the filter out, and dispose of it. Push the remaining filter back in, and there you have it - a inconspicious looking cigarette that packs the punch of having no filter - also, since the cigg paper burns faster than rolling paper, lick the top half of the CJ on 2 sides, so it'll burn much slower and in a much more even fashion.
As for hash, before you break it up - take about 10 minutes rubbing it down - by this I mean apply a little saliva to it in your hand, and knead it as if it were bread dough - in a few minutes even the hardest hash will become pliable. this compression of the resin creates a much more potent high, and it last longer, and cuts the risk of a headache down. Once the hash is pliable, take a piece, attatch it to a pokey, burn it for about 10 seconds (more depending on size and hardness) - at this point, it's lost no THC, but it literally melts over the tabbaco, giving a smooth sheen, devoid of rocky bits. it'll smoke cleanly, and no frags will fall to burn ones clothes.
Hope it helped
