If opium were the only drug of abuse and if the only kind of abuse were one of habitual, compulsive use, discussion of addiction might be a simple matter. But opium is not the only drug of abuse, and there are probably as many kinds of abuse as there are drugs to abuse or, indeed, as maybe there are persons who abuse.

Various substances are used in so many different ways by so many different people for so many different purposes that no one view or one definition could possibly embrace all the medical, psychiatric, psychologicalsociological, cultural, economic, religious, ethicaland legal considerations that have an important bearing on addiction. Prejudice and ignorance have led to the labelling of all use of nonsanctioned drugs as addiction and of all drugs, when misused, as narcotics.

The continued practice of treating addiction as a single entity is dictated by custom and law, not by the facts of addiction.

Alcohol and drug addiction

The tradition of equating drug abuse with narcotic addiction originally had some basis in fact. Historically, questions of addiction centred on the misuse of opiates, the various concoctions prepared from powdered opium. Then various alkaloids of opium, such as morphine and heroinwere isolated and introduced into use. Being the more active principles of opium, their addictions were simply more severe.

Later, drugs such as methadone and Demerol were synthesized but their effects were still sufficiently similar to those of opium and its derivatives to be included in the older concept of addiction. With the introduction of various barbiturates in the form of sedatives and sleeping pills, the homogeneity of addictions began to break down.

Then came various tranquilizers, stimulantsnew and old hallucinogens, and the various combinations of each. At this point, the unitary consideration of addiction became untenable. Legal attempts at control often forced the inclusion of some nonaddicting drugs into old, established categories—such as the practice of calling marijuana a narcotic.

Problems also arose in attempting to broaden addiction to include habituation and, finally, drug dependence. Unitary conceptions cannot embrace the diverse and heterogeneous drugs currently in use. Common misconceptions concerning drug addiction have traditionally caused bewilderment whenever serious attempts were made to differentiate states of addiction or degrees of abuse. For many years, a popular misconception was the stereotype that a drug user is a socially unacceptable criminal.

The carryover of this conception from decades past is easy to understand but not very easy to accept today. A second misconception involves the ways in which drugs are defined.

Caffeinenicotineand alcohol are clearly drugs, and the habitual, excessive use of coffeetobacco, or an alcoholic drink is clearly drug dependence if not addiction. The same could be extended to cover teachocolatesor powdered sugarif society wished to use and consider them that way.

The task of defining addiction, then, is the task of being able to distinguish between opium and powdered sugar while at the same time being able to embrace the fact that both can be subject to abuse. This requires a frame of reference that recognizes that almost any substance can be considered a drug, that almost any drug is capable of abuse, that one kind of abuse may differ appreciably from another kind of abuse, and that the effect valued by the user will differ from one individual to the next for a particular drug, or from one drug to the next drug for a particular individual.

This kind of reference would still leave unanswered various questions of availability, public sanction, and other considerations that lead people to value and abuse one kind of effect rather than another at a particular moment in history, but it does at least acknowledge that drug addiction is not a unitary condition.

Certain physiological effects are so closely associated with the heavy use of opium and its derivatives that they have come to be considered characteristic of addictions in general. Some understanding of these physiological effects is necessary in order to appreciate the difficulties that are encountered in trying to include all drugs under a single definition that takes as its model opium. Tolerance is a physiological phenomenon that requires the individual to use more and more of the drug in repeated efforts to achieve the same effect.

At a cellular level this is characterized by a diminishing response to a foreign substance drug as a result of adaptation. Although opiates are the prototypea wide variety of drugs elicit the phenomenon of tolerance, and drugs vary greatly in their ability to develop tolerance. Opium derivatives rapidly produce a high level of tolerance; alcohol and the barbiturates a very low level of tolerance.

Tolerance is characteristic for morphine and heroin and, consequently, is considered a cardinal characteristic of narcotic addiction. In the first stage of tolerance, the duration of the effects shrinks, requiring the individual to take the drug either more often or in greater amounts to achieve the effect desired.Drug addiction, also called substance use disorder, is a disease that affects a person's brain and behavior and leads to an inability to control the use of a legal or illegal drug or medication.

Substances such as alcohol, marijuana and nicotine also are considered drugs. When you're addicted, you may continue using the drug despite the harm it causes. Drug addiction can start with experimental use of a recreational drug in social situations, and, for some people, the drug use becomes more frequent. For others, particularly with opioids, drug addiction begins with exposure to prescribed medications, or receiving medications from a friend or relative who has been prescribed the medication.

The risk of addiction and how fast you become addicted varies by drug. Some drugs, such as opioid painkillers, have a higher risk and cause addiction more quickly than others. As time passes, you may need larger doses of the drug to get high. Soon you may need the drug just to feel good. As your drug use increases, you may find that it's increasingly difficult to go without the drug.

Attempts to stop drug use may cause intense cravings and make you feel physically ill withdrawal symptoms.

You may need help from your doctor, family, friends, support groups or an organized treatment program to overcome your drug addiction and stay drug-free. Sometimes it's difficult to distinguish normal teenage moodiness or angst from signs of drug use. Possible indications that your teenager or other family member is using drugs include:. Signs and symptoms of drug use or intoxication may vary, depending on the type of drug.

Below you'll find several examples. People use cannabis by smoking, eating or inhaling a vaporized form of the drug.

Cannabis often precedes or is used along with other substances, such as alcohol or illegal drugs, and is often the first drug tried. Two groups of synthetic drugs — synthetic cannabinoids and substituted or synthetic cathinones — are illegal in most states. The effects of these drugs can be dangerous and unpredictable, as there is no quality control and some ingredients may not be known. Synthetic cannabinoids, also called K2 or Spice, are sprayed on dried herbs and then smoked, but can be prepared as an herbal tea.

Despite manufacturer claims, these are chemical compounds rather than "natural" or harmless products. These drugs can produce a "high" similar to marijuana and have become a popular but dangerous alternative. Substituted cathinones, also called "bath salts," are mind-altering psychoactive substances similar to amphetamines such as ecstasy MDMA and cocaine.

Packages are often labeled as other products to avoid detection. Despite the name, these are not bath products such as Epsom salts.

Substituted cathinones can be eaten, snorted, inhaled or injected and are highly addictive. These drugs can cause severe intoxication, which results in dangerous health effects or even death. Barbiturates, benzodiazepines and hypnotics are prescription central nervous system depressants. They're often used and misused in search for a sense of relaxation or a desire to "switch off" or forget stress-related thoughts or feelings. Stimulants include amphetamines, meth methamphetaminecocaine, methylphenidate Ritalin, Concerta, others and amphetamine-dextroamphetamine Adderall, Adderall XR, others.

They are often used and misused in search of a "high," or to boost energy, to improve performance at work or school, or to lose weight or control appetite. Club drugs are commonly used at clubs, concerts and parties. These drugs are not all in the same category, but they share some similar effects and dangers, including long-term harmful effects.Some interactive areas of this site require javascript to function and so will be disabled until you re-enable it.

You are only a five minute phonecall away from success. If you are concerned about someone who may have an alcohol problem, you can do something by way of an intervention.

An intervention attempts to break through that fog into the realm of reality.

If you think an intervention may be appropriate for your loved one, there are a couple of options:. They meet with the intervention team, advise them in planning a strategy, and lead the intervention when the time comes. Professional assistance can be very beneficial if you are not comfortable conducting an intervention on your own. It still requires a team of individuals willing to work together.

Desolation by Fraser Bremner

Experts suggest the intervention team be made up of family members, close friends, and, when appropriate, employers or co-workers. Each team member must be close enough to the individual to have a personal impact.

Drug Abuse

Individuals the alcoholic barely knows are not likely to be helpful. When it is time to conduct an intervention, everyone gathers in a neutral place to avoid a confrontational atmosphere. A neutral place may be in the office of a professional counsellor, at a public park, or at the home of an individual not participating in the event. Each member of the intervention team then takes his or her turn addressing the alcoholic.

It should be done in an orderly and deliberate manner to avoid confusion or the possibility of passions running too high. Remember that in intervention is intended to be helpful, not chase the alcoholic away. In most cases, an intervention that has been well planned and executed will result in the alcoholic at least acknowledging he or she has a problem.

From there the intervention team must be ready to act immediately to get the alcoholic admitted to a programme. It is always a good idea to seek some advice from a professional even if you intend to conduct an independent intervention. In the meantime, here are some helpful tips to consider:. Going longer only opens the door to emotions getting out of control.Science writer Tabitha M. Tabitha M. Our flourishing knowledge of the brain is in large part the product of research on addiction.

Identifying what happens in the brain when a drug is inhaled, injected, or eaten, why it leads to compulsive drug seeking, and learning how to disrupt that process has seemed like the last best hope for a permanent fix for addiction. Which is why, according to Alan Leshner, director of the National Institute on Drug Abuse NIDAresearchers know more about drugs in the brain than they know about anything else in the brain.

Among the revelations: addiction is now seen to be a brain disease triggered by frequent use of drugs that change the biochemistry and anatomy of neurons and alter the way they work.

Scientists have developed a basic model of addiction that presents these changes as the desperate attempt of the brain to carry on business-as-usual—to make neurons less responsive to the drugs and so restore homeostasis—while under extreme chemical siege.

But the adaptations the drugs force on the brain can be long term or even permanent. With sustained drug use, the brain adapts to this saturation bombardment, and giving up drugs leaves it bereft and demanding a return to the new homeostasis.

Thus, even the brains of people who have quit using drugs and urgently wish to stay clean remain vulnerable to relapse. Deprived addicts are no longer seeking to get high, they just want to feel normal. Genetic factors, environmental factors, and—most important—the intricate and still mysterious interaction of the two are assumed to be fundamental to the addiction process.

But a great many critical details are emerging from studies of events in the brain. This pathway is involved in drug addictions of all kinds—not just addiction to illegal drugs such as heroin and cocaine, but also addiction to alcohol, tobacco, and even caffeine. Marijuana appears to employ this pathway too.

The addiction pathway is the brain system that governs motivated behavior. When the pathway was first discovered, almost a half-century ago, people called it the pleasure center. Scientists now call it the brain reward region and have confirmed its role as the addiction pathway in countless animal studies mostly with rats and mice and many brain-imaging studies of human addicts.

The pathway is hidden deep within the brain see illustration page It begins at the ventral tegmental area in the midbrain, which sits on top of the brainstem. In evolutionary terms, this region is very old; it began with the vertebrates, which appeared million years or so ago.

The pathway extends to the nucleus accumbens, toward the front of the brain. This area is a traffic hub for signals to and from the addiction pathway and other parts of the brain. The nucleus accumbens is centrally located at the intersection of the stria-turn where motion is begun and controlled and the limbic system. The limbic system is a collection of primeval brain structures that form a ring around the brain stem.

Among those structures are the hippocampus, the brain's center of learning and memory, and the amygdala, the postulated site of, among other things, our emotional responses to experience. These are ancient centers of cognitive processing, but they still guide our behavior, sometimes to our woe.

They long antedate the neocortex, where among other tasks rational thought processes are believed to take place. The limbic system is also closely connected to the hypothalamus, a tiny area in the center of the brain that controls many hormones, and with them, hunger, thirst, and sexual desire.

In short, the addiction pathway has been around a lot longer than humanity and is situated within easy reach of ancient brain centers that control many basic functions, most of them unconscious, that people share with other animals. Chemicals called neurotransmitters pass messages from one neuron to another across the gaps synapses that divide them. Dopamine is among the most common of the more than neurotransmitters that have been identified so far, although it is made in perhaps fewer thannerve cells out of the brain's billion.Get the latest information from CDC coronavirus.
