Let’s begin this theory by using nicotine as an example and by taking a close look at an impressive study in the scientific literature (see HERE).

Our body, upon beginning the habit of consuming nicotine, at first fires its receptors more frequently than usual upon each exposure to this drug. This leads to feeling more alert, which some of us experience as rather pleasant. But your body recognizes that if you were to keep firing those receptors at the pace that occurs when you first start smoking, certain functions in your body will end up exhausted. Thus, your body starts to reduce the number of these receptors. In the scientific literature, this process is called “down regulation” or “tolerance.”

For smokers, we see evidence of tolerance in studies that indicate fewer responses than do non-smokers to the same amount of nicotine (Perkins et al. 2001b). More specifically, we see a reduction on measures of subjective stimulation that may be viewed as pleasurable, such as arousal, vigor, and a subjective experience often referred to as “head rush” or “buzz.”

Once the down regulation process is complete, you end up with enough receptors to function fairly well as long as you continue to consume using this drug. However, shortly after you pause from smoking even for a few minutes, you end up not having enough of these receptors to do what they were originally designed to do. It is this shortage of receptors that occurs when there is not enough nicotine in your system to keep your receptors firing at a rate that would typically occur if you were not regularly consuming the drug that leads to the uncomfortable, sluggish, stressful feelings that lead to a craving for the next cigarette. When you light up, you feel relief because now the reduced amount of receptors are sufficient to carry out your major life functions in a less distressed manner.

The relief that smokers feel each time they give themselves another dose of nicotine creates the powerful illusion that cigarettes help them to deal with stress. Thus, in a study published in the American Psychologist, researchers found the following:

Smokers often report that cigarettes help relieve feelings of stress. However, the stress levels of adult smokers are slightly higher than those of nonsmokers, adolescent smokers report increasing levels of stress as they develop regular patterns of smoking, and smoking cessation leads to reduced stress. Far from acting as an aid for mood control, nicotine dependency seems to exacerbate stress. This is confirmed in the daily mood patterns described by smokers, with normal moods during smoking and worsening moods between cigarettes. Thus, the apparent relaxant effect of smoking only reflects the reversal of the tension and irritability that develop during nicotine depletion. Dependent smokers need nicotine to remain feeling normal. The message that tobacco use does not alleviate stress but actually increases it needs to be far more widely known.

Theoretically, this same process is largely the reason why people become addicted to other substances, such as alcohol, caffeine, illegal drugs, and even the drugs that psychiatrists prescribe, such as the so called antianxiety drugs (anxiolytics), antidepressants, and ADHD stimulants such as Ritalin. They all have the potential of creating for addicted people the illusion that they are functioning better than they did before they started consuming the addictive drug.

Another major part of the addiction process is that the addictive substance often is used as part of a ceremony creating a very pleasant experience. As an example of this, listen to the actor John Cusack explaining his smoking habit:

Although the cigarette habit is not John’s cup of tea, many people have fond associations of sharing a cigarette with others, and drinkers have associations of some very good times hanging out with their buddies. Of course, others have very negative associations with an addictive substance.

Clearly, regular users of alcohol go through a withdrawal reaction when they don’t get a drink around the time they usually imbibe. We get a delightful sense of this listening to Jimmy Buffet singing about it being five o’clock somewhere and his desire for the relief he needs by taking a swig of his favorite intoxicating drink.

How intense the need can become is powerfully brought home to us during Ray Milland’s Academy Award winning portrayal of Mr. Birnam, an alcoholic in the movie, “The Lost Weekend.”

Consider Jerry Irby who tells us in his song, One Cup of Coffee and a Cigarette:

Now when I get up in the morning

And I’m feeling mighty low

There’s just one thing that will pep me up

And I want you all to know.

Well it happens every morning

No matter where I’m at

I just gotta have a cup of coffee
And a cigarette

Coffee, coffee,
And a Cigarette
Is a habit
That you can’t forget…

Different people find some drugs pleasant when they first try them while others are not. I know someone, for example, who loves his cigarettes but doesn’t like how marijuana makes him feel. The process that doctors use when trying different prescriptions until one is found that the user happens to feel better on serves this illusion creating process perfectly.

Support for the theory I am putting forth comes from several studies.

People Who Get Over Depression Without “Antidepressants” Do Better Than Those Who Had Taken Them

A recent publication in the journal American Psychologist by Professor Steven Hollon neatly summarizes what I am referring to.

Depression is an inherently temporal phenomenon. Any given episode tends to remit spontaneously even in the absence of treatment but recurrence is common (at least among people seeking treatment). There is reason to believe that depression may be an evolved adaptation (like pain or anxiety) that increases reproductive fitness (the likelihood that one’s gene line will pass on). If so, then any treatment that facilitates the functions that depression evolved to serve is likely to be preferred to one that only anesthetizes the distress.  

After this opening statement, Prof. Hollon provides a more complete description of his theory:

Depression is an adaptation that evolved because it keeps organisms focused on (ruminating about) complex social issues until they can be resolved and that medications work not so much by addressing a nonexistent deficit in neurotransmitters in the synapse as by perturbing underlying regulatory mechanisms to the point that they reassert homeostatic control over those systems. If the latter is true then medications may work to suppress symptoms in a manner that leaves the underlying episode unaddressed and patients at elevated risk of relapse whenever they are taken away. 

So, I hope you will consider this theory of the illusion regarding how helpful these drugs are and please feel free to express your reactions in the comment section below.
