Encyclopedia > Cold water extraction

Cold water extraction is the process whereby a substance is extracted from a mixture via cold water.


The process generally involves taking a mixture of substances, and dissolving them into warm water, and then cooling the mixture. The insoluble compounds precipitate out of the water, while the soluble ones stay dissolved; thus extracting one from the other. This process works because some substances' solubility in water varies with temperature, enabling one to dissolve a compound in hot water and extract it as the mixture cools down.


Codeine extraction

In many countries tablets are available containing 300mg of aspirin, paracetamol (acetaminophen) or ibuprofen in combination with 8mg of codeine (or 30mg of codeine in the case of Tylenol 3), an opiate. Cold water extraction of codeine from these painkiller tablets has become popular amongst recreational drug users as it speeds up absorption and reduces hepatotoxicity caused by the APAP (acetaminophen) or ibuprofen. This practice can be performed on any opiate available in powder-based pill form, although it would be unnecessary to perform it on strong opiates such as oxycontin or morphine sulphate, because those drugs are available unadulterated, unlike lesser opiates such as codeine, oxycodone (PercocetĀ®) or hydrocodone (VicodinĀ®), which are usually combined with an over-the-counter painkiller, such as those previously mentioned, that are toxic in high doses whereas the opiates themselves are not. Aspirin or acetylsalicylic acid is a drug in the family of salicylates, often used as an analgesic (against minor pains and aches), antipyretic (against fever), and anti-inflammatory. ... Paracetamol (INN) (IPA: ) or acetaminophen (USAN) is a common analgesic and antipyretic drug that is used for the relief of fever, headaches, and other minor aches and pains. ... Acetaminophen (USAN) or paracetamol (INN), is a popular analgesic and antipyretic drug that is used for the relief of fever, headaches, and other minor aches and pains. ... Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) widely marketed under various trademarks including Act-3, Advil (A portmanteau of Advise and Pill)[citation needed], Brufen, Motrin, Nuprin, and Nurofen. ... The term opiate refers to the alkaloids found in opium, an extract from the seed pods of the opium poppy (). It has also traditionally referred to natural and semi-synthetic derivatives of morphine. ... Codeine (INN) or methylmorphine is an opioid used for its analgesic, antitussive and antidiarrheal properties. ... MS Contin® is a time-released formulation of morphine, usually taken every eight hours for chronic pain. ... Oxycodone is a very powerful and potentially addicting opioid analgesic medication synthesized from thebaine. ... Hydrocodone or dihydrocodeinone (marketed as Vicodin, Anexsia, Dicodid, Hycodan, Hycomine, Lorcet, Lortab, Norco, Hydroco, Tussionex, Vicoprofen) is an opioid derived from either of the naturally occurring opiates codeine or thebaine. ...


Per nominal cold water extraction, the tablets are first crushed and dissolved into some warm water. The solution is then cooled in a refridgerator or freezer and then, afterwards, filtered (typically with a coffee filter or something similar) to remove the unwanted compounds which precipitate after the solution has been cooled. The remaining liquid containing the opiate without the analgesic compound is then consumed orally as a liquid or left to dry, then scraped together and smoked or injected. The term filter may refer to: A device to separate mixtures. ...


This use of this process has in part led to tighter enforcement of Perscription Drug Laws involving opiates in the USA as the number of Recreational Drug users of opiates has increased in the Teen and Adult age groups.
