This is the only true way to spot N-isopropylbenzylamine at first contact seeing as though your advice thinks shards will be purely fake or purely real. We also call it crackback for simplicity when we dissolve in water and let it evaporate and form shard again. The same rules apply, if it crumbles into pieces it's iso, if it doesn't break at all or in half then you've most likely found some legit meth.Ī crackback crushes a shard.? What? Crackback is a slang term for recrystalization after heating until liquid state from solid salt form. Another easy way is by just pinching it between your thumb and index finger pretty hard. It will break in half or maybe thirds depending on where the pressure is focused on the crystal's surface and existing fracture lines.
Some of it will turn into powder, or dust (hence the street name, dust) and other parts turn into pieces about the size of a grain of rice. The key is to see how it breaks, Iso crystals are more brittle than meth which cause them to crumble by putting a little pressure on it. Real meth will take some force to, if you're even able to break it like that. Go ahead and press harder until it gives. But if it doesn't, don't stop and think its real. This usually causes it to break if its iso. Put it on a hard surface then press the flat pad of your index finger onto the crystal with just a little more pressure than it takes to pick it up by having it stick to your finger for a moment. Take out a crystal about the size of a kernel of popcorn. This is an easy but effective test to determine if you have iso. I meant to say crush but autocorrect filled in. I found this online and think it's a very good explanation on how to tell if your meth is without iso and possibly good shard.ĮDIT: Crackback is the wrong term.
