In these remote areas, processing laboratories are set up to extract the coca from the leaves and then convert the coca into cocaine. There are two types of processing labs: pozo pit labs that use acidic solutions, and the more common lab that uses metal drums and gasoline.
- Step One
Cocaine is typically processed in jungle labs by first soaking leaves in gasoline inside metal drums.
- Step Two
Gasoline containing cocaine alkaloid is drained from metal drums and filtered into a barrel with diluted acid. The gasoline will be removed from the acid layer and sodium bicarbonate or ammonia will be added to the solution to make cocaine base.
- Step Three
Cocaine base is filtered through a cloth.
- Step Four
The remaining substance is dried, resulting in a purer form of cocaine base.
- Step Five
Cocaine base is dissolved in a solvent such as ethyl acetate, acetone, or ether and then heated in a hot water bath called a “bańo maria.” Another solvent such as methyl ethyl ketone is added to the boiling liquid along with concentrated hydrochloric acid which results in the crystallization of cocaine hydrochloride.
- Step Six
Excess solvents are removed from the cocaine hydrochloride, first by hand, and then using a hydraulic press.
- Step Seven
Solvents are finally removed using microwave ovens creating the basis for powder cocaine.
- Step Eight
Cocaine base, commonly called “crack,” is typically made by dissolving cocaine hydrochloride in a mixture of water and baking soda. The solution is boiled until the cocaine forms an oily substance that drops out of the solution and settles at the bottom of the container.
- Step Nine
Excess water, sodium chloride, and other impurities can be removed after cooling the oil to a rock-like substance. The resulting product is crack cocaine."
