Nicotine Paradox and Gender Differences in Schizophrenia
This paper addresses two related questions in health psychology and neuroscience. The first examines Nesbitt's Paradox: the observation that smokers report feeling relaxed after nicotine use, despite nicotine being a biological stimulant. The paper explains this through the lens of nicotine addiction and withdrawal, mood normalization, and individual differences in anxiety sensitivity. The second question surveys the biological factors underlying gender differences in schizophrenia, including earlier male onset, poorer male outcomes, and the potential protective role of estrogen. The paper reviews relevant research while acknowledging methodological limitations, confounding social variables, and the roles of genetics, hormones, and neurodevelopment.

What makes this paper effective
- Anchors both arguments in named theoretical constructs (Nesbitt's Paradox, mood normalization) and then systematically unpacks each with supporting citations.
- Acknowledges methodological limitations in the cited research — such as uneven sample sizes in schizophrenia studies — demonstrating critical reading rather than passive summarizing.
- Balances biological and psychological explanations, avoiding reductive single-cause reasoning for complex phenomena.
Key academic technique demonstrated
The paper demonstrates effective use of counterevidence and qualification. Rather than simply asserting that nicotine withdrawal explains the paradox, the author introduces complicating variables — anxiety sensitivity, baseline arousal, and cognitive effects — and integrates them into a nuanced conclusion. Similarly, for schizophrenia, the paper explicitly flags confounding social variables before turning to the biological evidence, showing that strong academic writing anticipates and addresses alternative explanations.
Structure breakdown
The paper is divided into two discrete question-and-answer sections. The first (three to four paragraphs) moves from defining Nesbitt's Paradox, to the withdrawal explanation, to individual differences in anxiety, and finally to a summary of nicotine's direct biological effects. The second section (four to five paragraphs) opens by critiquing the research base, then moves progressively from behavioral outcomes to hormonal hypotheses to genetic and neurobiological factors. Each section ends by synthesizing findings rather than merely listing them.
Nesbitt's Paradox: Why Smokers Report Feeling Relaxed
One of the paradoxes about nicotine addiction is that smokers report feeling relaxed after using, in spite of the fact that nicotine is a biological stimulant. The phenomenon is known in the literature as Nesbitt's Paradox, or simply the nicotine paradox. Early research into Nesbitt's Paradox revealed that a number of potential variables influence the perception of a relaxed emotional response. Behavioral activity levels, the level of central nervous system arousal, the type of emotion being reported, time elapsed since the last nicotine fix, and both the rate and dose of administration are linked to perceived emotional responses to smoking cigarettes containing nicotine (Gilbert, 1979). Of these variables, the degree of nicotine deprivation has been most closely linked to the paradoxical sensation that a stimulant creates a relaxation response.
The solution to the paradox, then, is that addiction to nicotine creates sensations of anxiety, irritability, and distress, and these symptoms are alleviated by a "fix." As Parrott (2002) puts it, there is no paradox at all. Addiction creates withdrawal symptoms, which include heightened states of arousal. Smoking alleviates the withdrawal symptoms and therefore makes the smoker feel more relaxed.
Mood Normalization and the Role of Nicotine Withdrawal
One of the functions of smoking is "mood normalization," according to Parrott (2002, p. 27). In other words, smokers begin to need nicotine in order to "feel" or "function" normally (Parrott, 2002, p. 27). This would account for the fact that smokers report feeling more relaxed after smoking. The central nervous system is measurably aroused, and yet psychologically the person feels relieved after satisfying the craving that feeds the addiction.
It should also be noted that not all smokers report feeling reduced anxiety; many report feeling increased anxiety, agitation, and restlessness (Gilani, n.d.). How a person feels after smoking is related to how long the person has been addicted to cigarettes, how long the withdrawal period has lasted, and how anxiety-prone that person was regardless of smoking.
