I absolutely agree. In a time not so long ago, I remember taking a 2 hour road trip, talking the driver almost to insanity. All the while, heating my Chillum for who knows how long. As I'm babbling, not paying attention, I finally remember the beautiful finely ground white rail that lay in my lap, without a second thought, put the glowing orange tip... right to my nose, sizzzzzzle. Ew! What a rush that was and a drug free rush at that. Point is, if you Hot Rail, use caution with the hot end and be mindful where you place it if it has not cooled to a safe temp(not just your nose). But more commonly, as previously mentioned, inhaling too hot, too hard, several hundred degree vapor burns, takes your smell away, hurts, and makes the inside of your nostrils peel kinda like sunburn does. The tube cooling down below melting point half way through a rail and inhaling the other half unvaporized is a little unpleasant as well. And one more thing, if you don't keep it clean, use the tube continuously, the reclaim will of course liquify and drip when enough has built up. The drip burns like hell and it WILL leave one helluva blister followed by a nice scar. The 2 key things with hot railing, in my opinion, are getting the tip of the tube just the right temp and grinding your gear very fine on a ceramic or glass surface. Spin the tube while heating *glowing orange tip=too hot, let it cool some. Oh, and if ya got a stuffy nose, you will waste half your rail. So, not to sound like a hypochondriac, just sharing what I've learned... the way I learn everything in life, "Trial and Error" so maybe it can save ya some Trials and spare ya the Error. My daily R.O.A, my nose pockets solids, so there's a limited accepted volume for my nose, so vapors the only way I can go with todays %2 Ice/%98 ISO/MSM/whatever else to make the dope man an extra dollar.
