Specifically, those certain substances like nicotine release the pleasure chemical dopamine, and your body craves more of it-which leads to a habitual behavior to keep pumping dopamine into your system. Dopamine doesn't cause all addictions, but it may give some insight into the theory that such things as carbohydrates can be addictive. The feel-good chemical released after eating them is what drives the craving for more.
Lack of adequate sleep decreases the release of this feel-good chemical (and hormones as well). Not getting enough sleep may be one of the reasons you can get addicted to many of those aging simple carbohydrates and sugars, as well as the aging fats that are imposters of real food.

Addictions come in many forms. One could be addicted to such things as shopping, spending, gambling, overeating, undereating, sex, a relationship, drugs or alcohol, excessive exercise, working; and this list could go on and on. The bottom line is that many get into an addictive situation without ever intending to. They somehow lose themselves to the addictive agent, and before they know it, they feel as if they are unable to live without it. The agent gives them a temporary high that they continue to crave. They give their power away to this agent, many times at any cost. Sometimes the cost could be deadly. Because of their addiction, everything they have loved could be lost, including themselves.
People allude to addiction during everyday conversation, casually referring to themselves as "chocolate addicts" or "workaholics." Addiction is not a term clinicians take lightly. For the first time, and with considerable debate, the term "addiction" has appeared in a diagnostic manual (DSM5); this new classification includes “substance-related and addictive disorders.” In addition to substance use disorders, this addiction class now includes behavioral addiction (e.g., gambling disorder, which previously was classified as an impulse disorder). Historically, drug use disorders were divided into dependence and abuse categories. Now, substance use disorders only carry the moniker of "dependence."
Laypeople alike often use a conventional definition that invokes three C's:
- Craving for the object of addiction, which can be mild to intense
- Loss of Control over use of the object of addiction
- Continued engagement with the object of addiction despite adverse consequences.
To illustrate, the new DSM5 describes, “The essential feature of a substance use disorder is a cluster of cognitive, behavioral, and physiological symptoms indicating that the individual continues using the substance despite significant substance-related problems” (p. 483).

There are 2 physical hallmarks of addiction: tolerance and withdrawal. Tolerance is needing more and more of a substance or behavior to produce the same results. Withdrawal is the presence of symptoms when you try to take the substance or behavior away. If either one of these are present, addiction is present.
There are also psychological hallmarks of addiction: powerlessness, cravings, compulsivity, and consequences. Addicts report feeling powerless over their drug of choice, and admitting one's powerlessness is one of the key components in 12-step programs. Addicts may feel anything from a minor craving to an uncontrollable compulsivity drawing them to their drug of choice. No matter the addiction, consequences of greater and greater severity are almost always present. This downward spiral is when the addict reports reaching "rock bottom," and hopefully, this state will persuade him or her to seek treatment.
Addictions can be classified into 2 types: substance addictions and process addictions. Substance addictions means that you are ingesting a psychoactive substance such as drugs or alcohol. Process addictions include gambling, love, sex, and shopping. Food has traditionally been considered to be a process addiction, but recent studies suggest that food may actually fall into the substance addiction category.
During all the years I used heroin and opiates, I wanted to stop more times than I can count. I told myself that I will not use heroin/opiates any longer. I made a solemn vow that I would stop using but was never able to keep that vow. Over many years that vow would be made and then broken each time. When I finallly stopped using heroin/opiates, I thought I would be OK. I thought that heroin and opiates were my problem. I started smoking marijuana on a daily basis, thinking that since it wasn't physically addictive I could control my smoking and be able to stop when I wanted to. To my surprise, I couldn't stop smoking for one day even when I tried. I started to make the same solemn vow about not smoking marijuana as I did with heroin and opiates and I got the same broken vows over and over again.
This is addiction, the inability to stop even when you want to. Making promises over and over to your loved ones that you mean with all your heart, only to braeak those promises over and over again. This feeling of powerlessness creates the downward spiral of addiction.
Addiction will make you believe that you’re in control and you can stop using if you really wanted to, or it tells you that you can’t and that there is no hope. It will tell you that recovery will never work for you. Addiction is a liar.
Addiction is a brain disease. It is no different than diabetes, heart disease or cancer. It's a disease that comes with biological, psychological and social risk factors and causes. It can be prevented and treated. Untreated, it can last a lifetime.
Addiction is not a moral failing. It does not occur because somebody isn't ready to get serious about life. It doesn’t mean somebody's greedy or lacks good judgment. Addiction is characterized by continuing use or engagement in a behavior despite harmful consequences. It doesn't mean just drugs or alcohol. People can be addicted to shopping, gambling, internet use, work and exercise.
