A counterfeit medication or a counterfeit drug is a medication or pharmaceutical product which is produced and sold with the intent to deceptively represent its origin, authenticity or effectiveness. A counterfeit drug may contain inappropriate quantities of active ingredients, or none, may be improperly processed within the body (e.g., absorption by the body), may contain ingredients that are not on the label (which may or may not be harmful), or may be supplied with inaccurate or fake packaging and labeling. Medicines which are deliberately mislabeled to deceive consumers—including mislabeled but otherwise genuine generic drugs—are counterfeit. Counterfeit drugs are related to pharma fraud. Drug manufacturers and distributors are increasingly investing in countermeasures, such as traceability and authentication technologies, to try to minimise the impact of counterfeit drugs. 
Legitimate, correctly labeled, low-cost generic drugs are not counterfeit or fake (although they can be counterfeited), but can be caught up in anticounterfeiting enforcement measures. In that respect, a debate is raging as to whether "counterfeit products [are] first and foremost a threat to human health and safety or [whether] provoking anxiety [is] just a clever way for wealthy nations to create sympathy for increased protection of their intellectual property rights". Generic drugs are subject to normal regulations in countries where they are manufactured and sold.
Prescription and over-the-counter drugs
Counterfeit medicinal drugs include those with less or none of the stated active ingredients, with added, sometimes hazardous, adulterants, substituted ingredients, completely misrepresented, or sold with a false brand name. Otherwise, legitimate drugs that have passed their date of expiry are sometimes remarked with false dates. Low-quality counterfeit medication may cause any of several dangerous health consequences, including side effects or allergic reactions, in addition to their obvious lack of efficacy due to having less or none of their active ingredients.
Since counterfeiting is difficult to detect, investigate, quantify, or stop, the quantity of counterfeit medication is difficult to determine. In 2003, the World Health Organization cited estimates that the annual earnings from substandard and/or counterfeit drugs were over US$32 billion.
The considerable difference between the cost of manufacturing counterfeit medication and price counterfeiters charge is a lucrative incentive. Fake antibiotics with a low concentration of the active ingredients can do damage world wide by stimulating the development of drug resistance in surviving bacteria. Courses of antibiotic treatment which are not completed can be dangerous or even life threatening. If a low-potency counterfeit drug is involved, completion of a course of treatment cannot be fully effective. Counterfeit drugs have even been known to have been involved in clinical drug trials.
Several technologies may prove helpful in combating the counterfeit drug problem. An example is radio frequency identification, which uses electronic devices to track and identify items, such as pharmaceutical products, by assigning individual serial numbers to the containers holding each product. The U.S. Food and Drug Administration (FDA) is working towards an electronic pedigree (ePedigree) system to track drugs from factory to pharmacy. This technology may prevent the diversion or counterfeiting of drugs by allowing wholesalers and pharmacists to determine the identity and dosage of individual products. Some techniques, such as Raman spectroscopy and energy-dispersive X-Ray diffraction (EDXRD) can be used to discover counterfeit drugs while still inside their packaging.
The State Food and Drug Administration is not responsible for regulating pharmaceutical ingredients manufactured and exported by chemical companies. This regulatory lack, which has resulted in considerable international news coverage unfavorable to China, has been known for a decade, but failure of Chinese regulatory agencies to cooperate has prevented improvement. On May 6, 2005, the Chinese press agency Xinhua reported that the World Health Organization had established Rapid Alert System, the world's first web-based system for tracking the activities of drug counterfeiters, in light of the increasing severity of the problem of counterfeit drugs.
According to Outsourcing Pharma citing the European Commission, 75% of counterfeit drugs supplied world over have some origins in India, followed by 7% from Egypt and 6% from China.
The Central Drug Standards Control Organisation (CDSCO), the drug regulatory authority of India conducted a nation-wide survey in 2009 to put to rest these allegations of huge proportion of fake drugs being made in India. During the survey, over 24,000 samples were collected from all over India and tested. It was found that only 11 samples or 0.046% were spurious. An earlier survey funded by the World Health Organisation (WHO) and undertaken by the International Pharmaceutical Federation, a global federation representing three million pharmacists and pharmaceutical scientists worldwide, lifted and tested of 10,000 samples. In that survey 3.1% of drugs were found to be counterfeit. But counterfeit could just mean that they were copies of branded drugs. It does not mean that the ingredients in the drug were substandard or fake. These very low figures are a far cry from the ﬁgures quoted by media which range from 10% to 25% of drugs in the country being spurious drugs. “These are totally unsubstantiated reports. For example, on the basis of an alleged WHO report, the media frequently reports that 35% of fake drugs produced in the world come from India. However, when enquired, WHO has neither conﬁrmed its authenticity nor did it hint the source of such ﬁgures. WHO Representative in India has clariﬁed that there is no actual study by WHO concluding that 35% of the World spurious drugs are produced in India. He has also regretted that occasionally some individuals in the media and the organizations use WHO references incorrectly and even irresponsibly,” stated the CDSCO report. Despite such clarifications from the WHO, the media continue to repeat this figure.
The 2012 Pakistan fake medicine crisis revealed the scale of production of counterfeit medications in Pakistan. Over 100 heart patients died after administration of adulterated drugs by the Punjab Institute of Cardiology. Pakistan did not have any regulatory enforcement on production of medicines until this crisis occurred. In response to the crisis, a regulatory body was finally setup in February 2012.
The United States has a growing problem with counterfeit drugs. In 2012, tainted steroids killed 11 people near Boston and sickened another 100. In another case, vials of the cancer medicine Avastin were found to contain no active ingredients. The vials were sourced in Turkey, shipped to Switzerland, then Denmark, finally to the United Kingdom from which they were exported to U.S. wholesale distributors. The Wall Street Journal reported that the U.S. wholesale distributor was hired by Canada Drugs, which also owns CanadaDrugs.com, a retail pharmacy website that sells prescription medication internationally, with a focus on the American market.  In 2007-08, 149 Americans died from a contaminated blood thinner called Heparin that was legally imported into the United States. Investigated by the FDA Office of Criminal Investigations, the Albers Medical investigation is the most prolific example to date. On August 21, 2005, the U.S. Attorney’s Office for the Western District of Missouri issued a press release announcing that three businesses and eleven individuals were indicted for their involvement in a $42 million conspiracy to sell counterfeit, smuggled and misbranded Lipitor and other drugs and for participating in a conspiracy to sell stolen drugs. As part of this investigation, FDA initiated a recall of more than 18 million Lipitor tablets, which ranks as the largest recall in the history of criminal investigations of counterfeit medications. Participants in this scheme conspired to purchase and sell counterfeit, misbranded and illegally imported drugs. Foreign versions of Lipitor and Celebrex were smuggled into the U.S. from South America and re-sold after being re-packaged to conceal the true origin of the drugs. Counterfeit Lipitor also was manufactured in South America and then smuggled into the U.S. where it was co-mingled with the genuine foreign Lipitor and sold in the U.S. In addition, participants conspired to buy, sell and traffic almost eight million dollars worth of stolen Glaxo Smith Kline and Roche drugs, using fake pedigrees to launder the drugs and thereby concealing that they were stolen. There also were charges related to the sale of counterfeit Procrit, as well as counterfeit and misbranded Serostim and Neupogen. Procrit is an injectable drug used in the treatment of anemia and Neupogen is an injectable drug used by cancer patients to stimulate the production of white blood cells in order to decrease the incidence of infections.
The FDA held a Congressional hearing in 2005 to review the situation. The U.S. is an especially attractive market for counterfeiters because 40 percent of worldwide annual prescription drug sales were made in the United States in 2007. In 2011, a "PROTECT IP Act" was proposed to deter advertising.
Between 2002 to 2010, drug imports to the U.S. more than doubled, with 80% of drugs' active ingredients imported, now accounting for 40% of finished medicines.
Fake antimalarial medication has been threatening efforts to control malaria in Africa. According to the World Health Organization (WHO), in 2011, 64% of Nigeria's imported antimalarial drugs were fake. Nigeria is Africa's largest drugs market, and over 70% of its drugs are imported from India and China, considered the "biggest source of fakes."
In 2007, the world's first free-to-access anticounterfeit platform was established in the West African country of Ghana. The platform, dubbed mPedigree, relies on existing GSM networks in that country to provide pharmaceutical consumers and patients with the means to verify whether their purchased medicines are from the original source through a free two-way SMS message, provided the manufacturer of the relevant medication has subscribed to a special scheme. Still in trial stages, the implementers of the platform announced in 2009 that they are in partnership with Ghana's Ministry of Health and the country's specialized agency responsible for drug safety, the Food and Drugs Board, to move the platform from pilot to full-deployment stage. A similar service is being rolled out in India.
In 2010, NAFDAC in Nigeria launched an SMS-based anticounterfeiting platform using technology from Sproxil. That system was also adopted by GlaxoSmithKline (GSK) in February 2011. In April 2011, CNN published a video highlighting Sproxil's solution in the fight against counterfeit drugs in Nigeria. In July 2011, Kenya's Pharmacy and Poisons Board also adopted text message-based anticounterfeiting systems and endorsed the Sproxil solution. In early 2012 it was announced that more than one million people in Africa had checked their medicines using the text-message based verification service developed by Sproxil.
An ePedigree is another important system for the automatic detection of counterfeit drugs. States such as California are increasingly requiring pharmaceutical companies to generate and store ePedigrees for each product they handle. On January 5, 2007 EPCglobal ratified the Pedigree Standard as an international standard that specifies an XML description of the life history of a product across an arbitrarily complex supply chain.
Illegal drugs of abuse
Illegal drugs can be counterfeited easily because no standards or regulations govern them or their packaging though some examples of illegal drugs are sold under "brand names" to indicate certain standards or dosage levels were being adhered to, as in the case of 1960s-era LSD, which was sold with patterns or logos printed on blotter paper. These illegal "brands" can also be counterfeited by drug dealers who want to be able to sell their products at higher prices.
Counterfeit illegal and recreational drugs range from products which do not contain any active ingredients, as in cases where lactose powder is sold as heroin, or dried herbs such as oregano are sold as cannabis, to cases where the active ingredients are "cut" with a diluent (as in cases where cocaine is mixed with lactose powder), and cases where the claimed active ingredients are substituted by something cheaper (e.g., when methamphetamine is sold as cocaine).
The use of diluents in illegal drugs reduces the potency of the drugs and makes it hard for users to determine the appropriate dosage level. Diluents include "foodstuffs (flour and baby milk formula), sugars (glucose, lactose, maltose, and mannitol), and inorganic materials such as powder." The diluents used often depend on the way drug purchasers consume particular drugs. Drug dealers selling heroin to users who inject dilute the drug with different products from dealers selling to users who smoke or insufflate the drug; diluents which can easily form a solution with water for injecting heroin can be problematic for users who are sniffing the powder. When cocaine is mixed with diluents for the purpose of injection, the "...diluents can produce serious abscesses and pain if the user misses the vein and injects into muscle tissue." "Diluents and adulterants are often added to No. 3 heroin", including sugar, quinine, barbital and caffeine, some of which "can cause serious side effects." Dr. Hirsch, the New York Medical Examiner, claimed that buying illegal drugs is "... like playing Russian roulette," because "there is no way of knowing just what a heroin dealer has slipped into the packets." In some cases, if a dealer does not take the time to dilute the drug with lactose or other fillers, a "very potent blend of heroin" is sold, which can lead to overdoses.
Claims that illegal drugs are routinely cut with substances such as rat poison and crushed glass, often cited in antidrug pamphlets, are largely unsubstantiated.
Some countries, cities and organizations deploy drug checking services in order to improve the ability of users to make a more accurate risk assessment.
