Designer drug
A designer drug is a structural or functional analog of a controlled substance that has been designed to mimic the pharmacological effects of the original drug, while avoiding classification as illegal and/or detection in standard drug tests. Designer drugs include psychoactive substances that have been designated by the European Union, Australia, and New Zealand, as new psychoactive substances as well as analogs of performance-enhancing drugs such as designer steroids.''
Some of these designer drugs were originally synthesized by academic or industrial researchers in an effort to discover more potent derivatives with fewer side effects and shorter duration and were later co-opted for recreational use. Other designer drugs were prepared for the first time in clandestine laboratories. Because the efficacy and safety of these substances have not been thoroughly evaluated in animal and human trials, the use of some of these drugs may result in unexpected side effects.
The development of designer drugs may be considered a subfield of drug design. The exploration of modifications to known active drugs—such as their structural analogues, stereoisomers, and derivatives—yields drugs that may differ significantly in effects from their "parent" drug. In some instances, designer drugs have similar effects to other known drugs, but have completely dissimilar chemical structures. Despite being a very broad term, applicable to almost every synthetic drug, it is often used to connote synthetic recreational drugs, sometimes even those that have not been designed at all.
In some jurisdictions, drugs that are highly similar in structure to a prohibited drug are illegal to trade regardless of that drug's legal status. In other jurisdictions, their trade is a legal grey area, making them grey market goods. Some jurisdictions may have analogue laws that ban drugs similar in chemical structure to other prohibited drugs, while some designer drugs may be prohibited irrespective of the legal status of structurally similar drugs; in both cases, their trade may take place on the black market.
History
United States
1920s–1930s
Following the passage of the Second International Opium Convention in 1925, which specifically banned morphine and the diacetyl ester of morphine, heroin, a number of alternative esters of morphine quickly started to be manufactured and sold. The most notable of these were dibenzoylmorphine and acetylpropionylmorphine, which have virtually identical effects to heroin but were not covered by the Opium Convention. This then led the Health Committee of the League of Nations to pass several resolutions attempting to bring these new drugs under control, ultimately leading in 1930 to the first broad analogues provisions extending legal control to all esters of morphine, oxycodone and hydromorphone. Another early example of what could loosely be termed designer drug use, was during the Prohibition era in the 1930s, when diethyl ether was sold and used as an alternative to illegal alcoholic beverages in a number of countries.1960s–1970s
During the 1960s and 1970s, a number of new synthetic hallucinogens were introduced, with a notable example being the sale of highly potent tablets of DOM in San Francisco in 1967. There was little scope to prosecute people over drug analogues at this time, with new compounds instead being added to the controlled drug schedules one by one as they became a problem. One significant court case from this period was in 1973, when Tim Scully and Nicholas Sand were prosecuted for making the acetyl amide of LSD, known as ALD-52. At this time ALD-52 was not a controlled drug, but they were convicted on the grounds that in order to make ALD-52, they would have had to be in possession of LSD, which was illegal. The late 1960s also saw the introduction of various analogues of phencyclidine to the illicit market, with Eticyclidine first being detected in 1969.1980s–early 1990s
The modern use of the term designer drug was coined in the 1980s to refer to various synthetic opioid drugs, based mostly on the fentanyl molecule. The term gained widespread popularity when MDMA experienced a popularity boom in the mid-1980s. When the term was coined in the 1980s, a wide range of narcotics were being sold as heroin on the black market. Many were based on fentanyl or meperidine. One, MPPP, was found in some cases to contain an impurity called MPTP, which caused brain damage that could result in a syndrome identical to late stage Parkinson's disease, from only a single dose. Other problems were highly potent fentanyl analogues that caused many accidental overdoses.Because the government was powerless to prosecute people for these drugs until after they had been marketed successfully, laws were passed to give the DEA power to emergency schedule chemicals for a year, with an optional 6-month extension, while gathering evidence to justify permanent scheduling, as well as the analogue laws mentioned previously. Emergency-scheduling power was used for the first time for MDMA. In this case, the DEA scheduled MDMA as a Schedule I drug and retained this classification after review, even though their own judge ruled that MDMA should be classified Schedule III on the basis of its demonstrated uses in medicine. The emergency scheduling power has subsequently been used for a variety of other drugs including 2C-B, AMT, and BZP. In 2004, a piperazine drug, TFMPP, became the first drug that had been emergency-scheduled to be denied permanent scheduling and revert to legal status.
The late 1980s and early 1990s also saw the re-emergence of methamphetamine in the United States as a widespread public health issue, leading to increasing controls on precursor chemicals in an attempt to cut down on domestic manufacture of the drug. This led to several alternative stimulant drugs emerging, the most notable ones being methcathinone and 4-methylaminorex, but, despite attracting enough attention from authorities to provoke legal scheduling of these compounds, their distribution was relatively limited in extent and methamphetamine continued to dominate the illicit synthetic stimulant market overall.
Late 1990s–2004
In the late 1990s and early 2000s, there was a huge explosion in designer drugs being sold over the internet. The term and concept of "research chemicals" was coined by some marketers of designer drugs. The idea was that, by selling the chemicals as for "scientific research" rather than human consumption, the intent clause of the U.S. analogue drug laws would be avoided. Nonetheless, the DEA raided multiple suppliers, first JLF Primary Materials, and then multiple vendors several years later in Operation Web Tryp. This process was accelerated greatly when vendors began advertising via search engines like Google by linking their sites to searches on key words such as chemical names and terms like psychedelic or hallucinogen. Widespread discussion of consumptive use and the sources for the chemicals in public forums also drew the attention of the media and authorities.In 2004, the US Drug Enforcement Administration raided and shut down several Internet-based research chemical vendors in an operation called Web Tryp. With help from the authorities in India and China, two chemical manufacturers were also closed. Many other internet-based vendors promptly stopped doing business, even though their products were still legal throughout much of the world.
Most substances that were sold as "research chemicals" in this period of time are hallucinogens and bear a chemical resemblance to drugs such as psilocybin and mescaline. As with other hallucinogens, these substances are often taken for the purposes of facilitating spiritual processes, mental reflection or recreation. Some research chemicals on the market were not psychoactive, but can be used as precursors in the synthesis of other potentially psychoactive substances, for example, 2C-H, which could be used to make 2C-B and 2C-I among others. Extensive surveys of structural variations have been conducted by pharmaceutical corporations, universities and independent researchers over the last century, from which some of the presently available research chemicals derive. One particularly notable researcher is Alexander Shulgin, who presented syntheses and pharmacological explorations of hundreds of substances in the books TiHKAL and PiHKAL, and served as an expert witness for the defense in several court cases against manufacturers of psychoactive drugs.
The majority of chemical suppliers sold research chemicals in bulk form as powder, not as pills, as selling in pill form would invalidate the claims that they were being sold for non-consumptive research. Active dosages vary widely from substance to substance, ranging from micrograms to hundreds of milligrams, but while it is critical for the end user to weigh doses with a precision scale, instead of guessing, many users did not do this and this led to many emergency room visits and several deaths, which were a prominent factor leading to the emergency scheduling of several substances and eventually Operation Web Tryp. Some compounds such as 2C-B and 5-Meo-DiPT did eventually increase in popularity to the point that they were sold in pill form to reach a wider market, and acquired popular street names. Once a chemical reaches this kind of popularity, it is usually just a matter of time before it is added to the list of scheduled drugs.
The late 1990s and early 2000s also saw the first widespread use of novel anabolic steroids by athletes in competition. Steroids had been banned by the International Olympic Committee since 1976, but due to the large number of different anabolic agents available for human and veterinary use, the ability of laboratories to test for all available drugs had always lagged behind the ability of athletes to find new compounds to use. The introduction of increasingly formalised testing procedures, especially with the creation of the World Anti-Doping Agency in 1999, made it much more difficult for athletes to get away with using these drugs without detection, which then led to the synthesis of novel and potent anabolic steroid drugs such as tetrahydrogestrinone, which were not detectable by the standard tests.
