Recreational drug use

• 1. Defining The Altered State

  ›

  The Smokers, a 1636 portrait by Adriaen Brouwer, captures the quiet intimacy of tobacco use in the Dutch Golden Age. This image serves as an early visual record of recreational drug consumption, showing how altered states have long been woven into human culture. Recreational drug use is defined simply as the intake of one or more psychoactive drugs to induce an altered state of consciousness for pleasure or casual pastime. When such a substance enters the body, it triggers an intoxicating effect that changes perception and mood. Modern researchers divide these substances into three broad categories: depressants, stimulants, and hallucinogens. Depressants like alcohol create feelings of relaxation and calmness. Stimulants such as caffeine or cocaine generate energy and alertness. Hallucinogens including LSD produce perceptual distortions known as hallucinations. These classifications help medical professionals and policymakers understand the diverse impacts on the human mind.

  Anthropological research suggests humans may have evolved to counter-exploit plant neurotoxins found in nature. A typically restrictive prehistoric diet might have emphasized the apparent benefit of consuming psychoactive plants that had themselves evolved to mimic neurotransmitters. Chemical-ecological adaptations and the genetics of hepatic enzymes, particularly cytochrome P450, led researchers to propose that humans share a co-evolutionary relationship with psychotropic plant substances spanning millions of years. In modern times, addiction researcher Martin A. Plant notes that some people undergo self-redefinition before initiating drug use. They view using drugs as part of a general lifestyle involving belonging to a subculture associated with heightened status and challenging social norms. Plant states from the user's point of view there are many positive reasons to become part of the milieu of drug taking. The reasons for drug use appear to have as much to do with needs for friendship, pleasure and status as they do with unhappiness or poverty. Any number of factors influence an individual's drug use, including genetics, personality type, psychological problems, sex, age, depression, curiosity, boredom, rebelliousness, family attachment issues, history of trauma, socioeconomic stressors, peer pressure, juvenile delinquency, availability, historical factors, and socio-cultural influences.

  A 1914 photo shows intoxicated men in a sobering-up room, illustrating the immediate physical consequences of heavy substance use. Alcohol is sometimes considered one of the most dangerous recreational drugs despite its widespread legal acceptance. Alcoholic drinks, tobacco products, and other nicotine-based products like electronic cigarettes are regarded by various medical professionals as the most common gateway drugs. In the United States, Australia, and New Zealand, the general onset of drinking alcohol, tobacco smoking, cannabis smoking, and consumption of multiple drugs most frequently occurs during adolescence and in middle school settings. Some scientific studies in the early 21st century found that low to moderate levels of alcohol consumption might decrease risk of cardiovascular diseases, stroke, and cognitive decline. This claim has been disputed specifically by British researcher David Nutt, professor of neuropsychopharmacology at Imperial College London. He stated that studies showing benefits for moderate alcohol consumption lacked controls for variables regarding what subjects were drinking beforehand. Drug harmfulness is defined as the degree to which a psychoactive drug causes harm measured by addictiveness and potential for physical injury. More objectively harmful drugs may be colloquially referred to as hard drugs while less harmful ones become soft drugs. The term soft drug remains controversial among critics who argue it implies false beliefs about lesser or insignificant harm.

  Alcohol is the most widely used recreational drug in Australia where 86.2% of people aged 12 years and over have consumed it at least once in their lifetime. Only 34.8% of Australians aged 12 years and over have used cannabis at least once in their lifetime. From the mid-19th century to the 1930s American physicians prescribed Cannabis sativa as a prescription drug for various medical conditions. In the 1960s the counterculture movement introduced use of psychoactive drugs including cannabis. Young adults and college students reported recreational prevalence of cannabis among other drugs at 20-25% while cultural mindset remained open and curious. In 1969 the FBI reported that between years 1966 and 1968 arrests for marijuana possession had increased by 98%. Despite acknowledgement that drug use was greatly growing among America's youth during late 1960s surveys suggested only as much as 4% of American population had ever smoked marijuana by 1969. By 1972 that number would increase to 12%. That number would then double by 1977. The Controlled Substances Act of 1970 classified marijuana along with heroin and LSD as Schedule I drug having relatively highest abuse potential and no accepted medical use. Most marijuana at that time came from Mexico but in 1975 Mexican government agreed to eradicate crop by spraying it with herbicide paraquat raising fears of toxic side effects. Colombia then became main supplier.

  LSD is a popular ergoline derivative first synthesized in 1938 by Albert Hofmann who failed to notice its psychedelic effects until 1943. It is a serotonergic psychedelic partial agonist at serotonin receptors particularly 5-HT2A subtypes like psilocin mescaline and DMT. LSD is unique because it also acts as partial agonist of dopamine and norepinephrine receptors particularly D2R subtypes. In the 1950s it was used in psychological therapy and covertly by CIA in Project MKULTRA where drug was administered to unwitting US and Canadian citizens. It played central role in 1960s counter-culture before being banned in October 1968 by US President Lyndon B Johnson. Cannabis contains at least 85 cannabinoids with primary psychoactive component THC mimicking neurotransmitter anandamide named after Sanskrit word meaning joy bliss or delight. When cannabis is eaten THC metabolizes into 11-OH-THC which becomes primary psychoactive compound of edible forms. Cocaine available as white powder can be insufflated sniffed into nostrils converted into solution with water and injected. Popular derivative crack cocaine typically smoked when transformed into freebase form allows vapour inhalation directly thought to increase bioavailability but found toxic due production methylecgonidine during pyrolysis.
