Common questions

Where does pasta base fit in the cocaine production process?+

It is the crude intermediate precipitated from the acid-wash aqueous layer after initial solvent extraction of coca leaf, produced before further purification into cocaine hydrochloride.

Why is purity so variable in pasta base?+

Purity depends heavily on the extraction technique and the solvents and reagents used at small clandestine labs, and on how thoroughly plant material and other alkaloids were removed during processing.
