When it comes to what meth looks like, regular methamphetamine hydrochloride comes in powder form. A blue color means that one of the amines that goes into creating meth has been found. They can either test a suspected user’s blood or urine to find the drug or test for the drug itself by mixing it with a reagent. Law enforcement professionals use drug kits to check to see whether a substance is methamphetamine. Meth identification can be difficult, as the drug can resemble anything from bits of transparent quartz or other harmless minerals to rock candy or rock salt to talcum powder to the glaze placed on a donut. For this reason, it’s important to be able to identify meth by look, smell, and other factors. Active ingredients used to make meth interact in ways that can cause explosions and harm to anyone who may stumble upon the lab. Meth labs can be very potent and dangerous. These include nail polish remover, fertilizer, lithium, battery acid, and pseudoephedrine. Illicit meth is cooked in labs, often with inexpensive ingredients that can be easily found in drugstores or big box stores. The prescription treats obesity and attention-deficit/hyperactivity disorder and can’t be refilled. Methamphetamine is a Schedule II stimulant, which means that it does have medical use but is very addictive. Identifying meth may be important to those who are abusing drugs, or loved ones of addicted individuals, as meth is a highly addictive, dangerous drug of abuse and meth labs can be highly hazardous. If it's highly-cut, then this number will be about ten degrees lower by the time it's fully solid.Methamphetamine (meth) comes in many forms, each which may have a different look and smell. If it's pure, this temperature should not change much at all during solidification.

Pure methamphetamine should begin crystallization between 170˚C and 175˚C, and with cut methamphetamine this would happen at a lower temperature. As soon as it starts to form crystals, make a note of the temperature. Wait for it to all melt, then turn off the heat and start monitoring the temperature.

Eventually, the stuff in the tube will melt, and when it does, insert the thermometer. Put mineral oil or cooking oil or some other clear liquid with a high boiling point in the beaker, then put the test tube in that and heat it on a stove burner or a flame or something. Put as much of the alleged drugs in the test tube as you can. Get a glass thermometer than can measure up to at least 200˚C, a test tube, and a vial or a small beaker or something, that you can put the test tube in without it falling over.
