I can only assume the related compounds methyl- and ethyl- benzylamine carry some of those risks. Severe cases result in comas, seizures, and death. Symptoms include shortness of breath, discolored skin, headaches, fatigue, and loss of consciousness. All cocrystallize, have similar melting points, and have the same appearance as methamphetamine.Īs a warning, isopropylbenzylamine ingested regularly over time will cause methmoglobinemia. Compounds related to isopropylbenzylamine are also used as cutting agents such as methylbenzylamine and ethylbenzylamine. If a shard of methamphetamine placed in the bleach solution releases an oil, a cut is present although it is not possible to pinpoint the exact one. Bleach can be used as an indicator to hint at the presence of the compound. Unlike MSM, it is nearly impossible to purify the adulterant from meth. It cocrystallizes with methamphetamine and has an identical weight. It is a structural isomer of methamphetamine and has a very similar melting point which differs as little as 5 degrees. A reliable heating device like an oven could be used to remove some MSM in theory (250 degrees F off the top of my head, but don’t quote me on that).Ī much more sinister cut is that of isopropylbenzylamine. It’s a feeble attempt to sublime the MSM out before smoking, but I doubt it does much at an uncontrolled temperature that is not uniformly distributed. Many users do not inhale the first hit of meth when they begin to vaporize it. The vapor will also be somewhat cool feeling, like a hint of menthol. The entire pipe will be coated white inside.

One of the signs of methamphetamine cut with MSM is how thickly it coats the pipe after only two or so uses. No MSM is present in this methamphetamine (it sublimates around 250 degrees, while methamphetamine has a higher vaporization temperature). This methamphetamine cracks back instantly, failure to crackback or a large delay indicates impure product. When the heat source is removed, the puddle recrystallizes with an audible cracking sound.

Pure methamphetamine “cracksback” after it is liquefied by heat. I vaporized 30mg from a recently constructed lightbulb vape and found the vapor to be very smooth. The quality is top notch, melting point analysis showed absolutely no residue. The crystals break down just as pure methamphetamine should as MSM (Methylsulfonylmethane) and isopropylbenzylamine noticeably change how brittle they are. They are relatively clear and are not cloudy. The crystals are beautiful and translucent. New 1g of the best methamphetamine I’ve ever had the pleasure of coming across.
