Methamphetamine hydrochloride is a polar ionic salt. Its solubility in acetone is extremely low at low temperatures (e.g., < 0.1 g/100 mL at -20°C). Conversely, many common cutting agents and synthesis byproducts are highly soluble in acetone.
While acetone-free methods show promise, there are still challenges to overcome. These include: washing meth with acetone free
Spread the wet meth powder on a clean, dry glass dish. Allow it to air dry in a well-ventilated area for 24 hours. Residual acetone must fully evaporate. Do not apply heat – acetone vapors are explosive, and heat can degrade meth. Methamphetamine hydrochloride is a polar ionic salt
