I think people tend to go a bit overboard with this substance, either demonizing it or greatly overrating it. It's just another stimulant with its own pros and cons.
Sometimes I guess we all take the good with the bad. Also, most of us are good at lying to ourselves, and likely so were our ancestors and perhaps this sort of selective memory is an evolutionary advantage, who knows?
Hmmm. If it's reasonably pure gear, it just rolls between my fingers, no peeling skin. Either you're seeing bits of cut crumbling off, or something else is giving you dry skin on your fingers, and the shard is sort exfoliating… or it's also possible I just don't know what the fuck I'm talking about, and you've got some particularly gnarly tina ¯\_(ツ)_/¯
Methamphetamine hydrochloride is technically not caustic in the strict sense of the word. When dissolved in water, it tends to be slightly acidic. Conversely sodium hydroxide—aka “caustic soda”—is basic/alkaline and will raise pH. It will neutralize acids. There are acid burns, but there are also caustic burns that can be caused by, for instance, a hot lye solution (NaOH, again). To be fair, from a descriptivist standpoint, the words corrosive, acidic, and caustic are all commonly used interchangeably, so it's nothing to sweat. I just mean to point out there's a reason why lye is called “caustic soda” and it's relevant that it neutralizes acids. Meanwhile damage done to any dermal layer from methamphetamine seems more likely to be caused by excess hydrochloride used by the manufacturer, which is not uncommon.
It's not advised to do this. With heat and agitation, the NaHCO₃ would go into solution and preferentially bond its Na to the Cl molecule from Meth.HCl. This would result in the freeing up of alkaline meth, which is an oil and insoluble in water. As an oil, meth would need to be vaporized or swallowed, and if the latter method, meth will bond to the hydrochloric acid in the stomach to form the water-soluble salt methamphetamine.hcl once more. In other words, it's likely to lower the bioavailability if you add NaHCO₃ to a solution of crystal methamphetamine.
