Oxilorphan (INN, USAN) (developmental code name L-BC-2605) is an opioid antagonist of the morphinan family that was never marketed.[1] It acts as a μ-opioid receptor (MOR) antagonist but a κ-opioid receptor (KOR) partial agonist, and has similar effects to naloxone and around the same potency as an MOR antagonist.[2] Oxilorphan has some weak partial agonist actions at the MOR (with miosis, nausea, dizziness, and some euphoria observed)[3][4] and can produce hallucinogenic/dissociative effects at sufficient doses, indicative of KOR activation.[5] It was trialed for the treatment of opioid addiction, but was not developed commercially.[6] The KOR agonist effects of oxilorphan are associated with dysphoria, which combined with its hallucinogenic effects, serve to limit its clinical usefulness; indeed, many patients who experienced these side effects refused to take additional doses in clinical trials.[7] It has been encountered as a novel designer drug.[8]

Oxilorphan (INN, USAN) (developmental code name L-BC-2605) is an opioid antagonist of the morphinan family that was never marketed. It acts as a μ-opioid receptor (MOR) antagonist but a κ-opioid receptor (KOR) partial agonist, and has similar effects to naloxone and around the same potency as an MOR antagonist. Oxilorphan has some weak partial agonist actions at the MOR (with miosis, nausea, dizziness, and some euphoria observed) and can produce hallucinogenic/dissociative effects at sufficient doses, indicative of KOR activation. It was trialed for the treatment of opioid addiction, but was not developed commercially. The KOR agonist effects of oxilorphan are associated with dysphoria, which combined with its hallucinogenic effects, serve to limit its clinical usefulness; indeed, many patients who experienced these side effects refused to take additional doses in clinical trials. It has been encountered as a novel designer drug.
Opium (also known as poppy tears, or Lachryma papaveris) is the dried latex obtained from the seed capsules of the opium poppy Papaver somniferum. Approximately 12 percent of opium is made up of the analgesic alkaloid morphine, which is processed chemically to produce heroin and other synthetic opioids for medicinal use and for the illegal drug trade. Opium's main psychoactive alkaloids, primarily morphine, act on μ-opioid receptors, causing analgesia, with long-term use leading to tolerance and dependence. The latex also contains the closely related opiates codeine and thebaine, and non-analgesic alkaloids such as papaverine and noscapine. The traditional, labor-intensive method of obtaining the latex is to scratch ("score") the immature seed pods (fruits) by hand; The latex leaks out and dries to a sticky yellowish residue that is later scraped off and dehydrated. The English word for opium is borrowed from Latin, which in turn comes from Ancient Greek: ὄπιον (ópion), a diminutive of ὀπός (opós, 'juice of a plant'). The word meconium (derived from the Greek for "opium-like", but now used to refer to newborn stools) historically referred to related, weaker preparations made from other parts of the opium poppy or different species of poppies. The Mediterranean region holds the earliest archaeological evidence of human use of opium poppies dating back to before 5000 BCE, with cultivation beginning around 3400 BCE in Mesopotamia. Opium was widely used for food, medicine, ritual, and as a painkiller throughout ancient civilizations including Greece, Egypt, and Islamic societies up to medieval times. The production methods have not significantly changed since ancient times. Through selective breeding of the Papaver somniferum plant, the content of the phenanthrene alkaloids morphine, codeine, and to a lesser extent thebaine has been greatly increased. In modern times, much of the thebaine, which often serves as the raw material for the synthesis for oxycodone, hydrocodone, hydromorphone, and other semisynthetic opiates, originates from extracting Papaver orientale or Papaver bracteatum. In preparation for the Second World War, the U.S. Army contracted farmers in the State of Sinaloa, Mexico, to grow opium crops. This was to provide morphine (the gold standard of analgesia) for injured soldiers. Modern opium production, once widely prohibited, still involves large-scale cultivation—especially in Afghanistan—where it is harvested by scoring poppy pods to collect latex used for both illicit drugs and legal medicines, with recent Taliban-led reductions cutting cultivation in Afghanistan by over 95%. For the illegal drug trade, the morphine is extracted from the opium latex, reducing the bulk weight by 88%. It is then converted into heroin which is almost twice as potent.
Oxycodone, sold under the brand names Roxicodone and OxyContin (which is the extended-release form) among others, is a semi-synthetic opioid used medically for the treatment of moderate to severe pain. It is a highly addictive and commonly abused drug. It is usually taken orally, and is available in immediate-release and controlled-release formulations. Onset of pain relief typically begins within fifteen minutes and lasts for up to six hours with the immediate-release formulation. In the United Kingdom, it is available by injection. Combination products are also available with paracetamol (acetaminophen), ibuprofen, naloxone, naltrexone, and aspirin. Common side effects include euphoria, constipation, nausea, vomiting, loss of appetite, drowsiness, dizziness, itching, dry mouth, and sweating. Side effects may also include addiction and dependence, substance abuse, irritability, depression or mania, delirium, hallucinations, hypoventilation, gastroparesis, bradycardia, and hypotension. Those allergic to codeine may also be allergic to oxycodone. Opioid withdrawal may occur if rapidly stopped. Oxycodone acts by activating the μ-opioid receptor. When taken by mouth, it has roughly 1.5 times the effect of the equivalent amount of morphine. Oxycodone was originally produced from the opium poppy opiate alkaloid thebaine in 1916 in Germany. One year later, it was used medically for the first time in Germany. Oxycodone is available as a generic medication. In 2023, it was the 49th most commonly prescribed medication in the United States, with more than 13 million prescriptions. A number of abuse-deterrent formulations are available, such as in combination with naloxone or naltrexone.
Phencyclidine or phenylcyclohexyl piperidine (PCP), also known in its use as a street drug as angel dust among other names, is a dissociative anesthetic mainly used recreationally for its significant mind-altering effects. PCP may cause hallucinations, distorted perceptions of sounds, and psychotic behavior. As a recreational drug, it is typically smoked, but may be taken by mouth, snorted, or injected. It may also be mixed with cannabis or tobacco. Adverse effects may include paranoia, addiction, and an increased risk of suicide, as well as seizures and coma in cases of overdose. Flashbacks may occur despite stopping usage. Chemically, PCP is a member of the arylcyclohexylamine class. PCP works primarily as an NMDA receptor antagonist. PCP is most commonly used in the US. While usage peaked in the US in the 1970s, between 2005 and 2011, an increase in visits to emergency departments as a result of the drug occurred. As of 2022, in the US, about 0.7% of 12th-grade students reported using PCP in the prior year, while 1.7% of people in the US over age 25 reported using it at some point in their lives.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
