i heard air drying Ketamine is the best way.... i want more Ketamine and more purity... also how long will Ketamine last after it is cooked??? like will it still be good after couple of weeks? - how do u air dry it? do i just put the liq. on a dish and let it air dry, at room temperture.? for how long(how would i know it is ready or not).? do i cover the dish with another dish(to cover the liq.-like the microwave way?)??? please help..... thank you
