^Absolutely correct Tommyboy. Let's face it, Afghani-Paki-stan is gonna have an even harder time smuggling into you guys than it does into us, isn't it?

West Coast U.S. at least is all Mexican tar isn't it? Dunno what you get East Coast given European routes into you? In the 10 years I was using I saw tar once I think. Hard, smokeable rocks, and it was pretty damn good as it goes relative to what we had floating around at the time, but never again, and never once saw anything like what we used to call China White: i.e. none-smokeable gear that didn't require cooking with citric acid / vitamin C to shoot. It was all Afghani. No. 3 for our U.S. cousins? Smokeable brown type base H. BuddingPharmacist? It's Europe paying for all the guns this time round, which is only fair seeing as the U.S. paid for 'em last time round, but that's another thread entirely!
In the UK I was always told that brown H tends to get cut with rosin. i.e. violin bow resin. Think it's AKA idashine? Allegedly if you rub up the horse-hairs with a block of rosin you end up with a lovely amount of powder that melts to a deep caramel on foil, and runs nicely but leaves dirty, spattering residues and tastes fucking rank. Makes the gear look a bit more opaque on the foil or so I'm led to believe, decent gear being somewhat clearer? I can kinda see it but I'd sold me violin long before I got to try it meself, ironically so I could afford a coupla bags of H. What a kicker!
Was always under the impression that 'bash' is just cooked up paracetamol. Never did understand how that was any use as a cut apart from being bulky and looking brown, but known people get plenty nicked for having pans of it cooked off?
If the above is true, they both cook up well with citric, leaving very little residue on the spoon. Dread to to think what they do once injected but junkies don't care, do they?
