Swim has read many suggestions on making cocaine freebase. He has decided to: Mix with water, add ammonia drops until precipitation stops, and filter the lump of coke with a handkerchief, squeezing out all of the ammonia water, and drying. Are there any downsides to not using petroleum ether as a np solvent for extraction? Is there any loss of product? Is the product less pure? Any input will be greatly appreciated.
