This process is frequently done with baking soda (sodium bicarbonate), water, and a spoon. The net reaction when using sodium bicarbonate isĬoc-H+Cl− + NaHCO3 → Coc + H2O + CO2 + NaCl With Ammonium bicarbonate:Ĭoc-H+Cl− + NH4HCO3 → Coc + NH4Cl + CO2 + H2O With Ammonium carbonate:Ģ(Coc-H+Cl−) + (NH4)2CO3 → 2 Coc + 2 NH4Cl + CO2 + H2O Crack cocaine is frequently purchased already in rock form, although it is not uncommon for some users to "wash up" or "cook" powder cocaine into crack themselves.
