When and how does drug abuse start and progress?
Studies such as the National Survey on Drug Use and Health, formally called the National Household Survey on Drug Abuse, reported by the Substance Abuse and Mental Health Services Administration, indicate that some children are already abusing drugs at age 12 or 13, which likely means that some begin even earlier. Early abuse often includes such substances as tobacco, alcohol, inhalants, marijuana, and prescription drugs such as sleeping pills and anti-anxiety medicines. If drug abuse persists into later adolescence, abusers typically become more heavily involved with marijuana and then advance to other drugs, while continuing their abuse of tobacco and alcohol. Studies have also shown that abuse of drugs in late childhood and early adolescence is associated with greater drug involvement. It is important to note that most youth, however, do not progress to abusing other drugs.
Scientists have proposed various explanations of why some individuals become involved with drugs and then escalate to abuse. One explanation points to a biological cause, such as having a family history of drug or alcohol abuse. Another explanation is that abusing drugs can lead to affiliation with drug-abusing peers, which, in turn, exposes the individual to other drugs.
their substance abuse have high levels of risk factors with low levels of protective factors.Gender, race, and geographic location can also play a role in how and when children begin abusing drugs.
How does an addiction to drugs start?
The word “addiction” comes from a Latin term for “enslaved by” or “bound to.” Anyone who has struggled to overcome an addiction – or witnessed a loved one dealing with it – understands why.
It begs the question: Does anyone really want to be a captive to a chemical? Is a voluntary surrender? Self-sabotage? Or is it a cleverly disguised ambush?
This article explores the mystery of addiction. how lives can be seduced and sucked into a relentless downward spiral. Starting with one simple act. But what act might that be? Is one particular drug more of a culprit than another? And where is the point of no return, when addiction has a user firmly in its grip?
While debate seems to never end about which, if any, drugs are THE gateway to addiction, this truth remains: the seismic effects of a substance use disorder can swell from the smallest seed of surrender.
People are motivated by pleasure. While what brings about pleasure can differ from one person to another (sports, sex, music, art, nature, etc.), how the human brain processes pleasurable sensations is universal.
When people do something that makes them feel good, their brain releases dopamine to teach them to seek out this activity in the future for that good feeling to be repeated. The human brain stores these memories. The feeling is connected with what activated it.
In a healthy brain, dopamine is eventually reabsorbed. Dopamine levels return to normal. The euphoric feeling fades away. Life goes on. But the brain files the association away for future reference.
When a person takes drugs, the chemical functioning of the brain is altered. One of those changes is that the brain is made to produce more dopamine than it would for a non-drug-related reason. Reabsorption of the dopamine is blocked. There’s a prolonged sense of pleasure beyond what’s normal for the brain.
The sensations are so powerful and long-lasting than the brain urges the user to find more of what did it. Normal activities – once enjoyed – now fade in value to the user. Drugs become the only well of contentment
Eventually, the body and mind become so hooked on the drug of choice that to not take it again causes uncomfortable – possibly painful – withdrawal symptoms. It is at that point that a diagnosis of addiction is certain. Desire turns to craving, and living without drugs becomes unimaginable.
It is common knowledge that drug users often seek out more and more potent substances over time. The body’s tolerance to what was initially used is the reason for this course of action. It seems necessary. Pleasure seems harder to attain with the same drug. So, a more powerful (and addictive) drug is pursued.
As mentioned at the top, there is no global agreement about which drug(s) are the stepping stone into the world of drug addiction.
Certain drugs (like cocaine, heroin, and methamphetamines) are infamous for how they can mess up the brain. Most people know to beware of their potency and danger. Other substances (such as alcohol, marijuana and painkillers) tend to be viewed quite differently. For many Americans, they are deemed to be much less dangerous. But is this view accurate?
Indeed, on their own, these more generally accepted substances might not prove to be a danger to many. But when combined with certain risk factors, even these commonly used chemicals may pose a threat. In fact, such drugs may actually work to pull users toward more powerful – and more addictive – substances
Never the less: we have two kind of drugs, positive and negative, and dividing to two column depends to users.
