Research Career Summary
Overview: Since 1986, I have been continuously funded by NIH as Principal Investigator on research focused largely on two broad “themes.” One emphasizes translational studies drawing on preclinical findings to examine acute effects of nicotine (and cigarette smoking) that may explain the persistence of tobacco dependence in humans, and the second is aimed at improving clinical treatments for smoking cessation. Several of these NIH-funded projects address both themes, as basic research findings are then often followed by evaluation of their implications for clinical treatment. These include the first programmatic lab-based research in humans, to our knowledge, on: 1) nicotine and energy balance, to partly determine why smoking lowers body weight, which may help maintain smoking in those with weight concerns; 2) chronic tolerance to nicotine (tolerance being a classic hallmark of abused drugs) and examination of associations of tolerance with dependence; 3) discriminative stimulus effects of nicotine, believed related to nicotine reinforcement; and 4) sex differences in reinforcing and rewarding effects of nicotine vs. non-nicotine stimuli of smoking. The initial key to all these projects was our development of a novel nasal spray method to administer measured doses of nicotine per se in rapid fashion, to mimic the speed of intake via cigarette smoking, but in isolation from all the other constituents in tobacco smoke. The first two decades of this effort resulted in my being listed among the most cited authors in tobacco and nicotine research (Byrne & Chapman, 2005, Tobacco Control, 14, 155-160), as well as the most productive faculty in clinical psychology (Stewart et al., 2007, Journal of Clinical Psychology, 63, 1209-1215). Today, another decade later, I am author or co-author of over 250 publications, most as first author, with a citation index (h) of 66 and over 13,000 total citations through 2017. More recent projects continue these themes, as one (translational) evaluates nicotine’s reinforcement enhancing effects in humans, and a second (clinical) involves developing and validating an efficient and innovative procedure for initial screening of novel medications for evidence of smoking cessation efficacy. A third project extends testing of nicotine discrimination (#3 above) to cigarette smoking, for the first time. In addition to this research productivity over the past 30 years, I have also contributed to the missions of the medical school and the Psychology department at the Univ of Pittsburgh by teaching and mentoring graduate students and medical students. These projects are summarized in chronological order below.
1. Nicotine and Energy Balance: This early project provided the first full characterization of nicotine acute influences on energy expenditure (“metabolic rate”) under various conditions (e.g. during rest or light activity, following food intake or other drug use). Notable was showing its enhancement during light physical activity, suggesting nicotine’s influence on energy expenditure in the natural environment, while smokers are “busy” with routine tasks, is greater than that observed while under standard resting laboratory conditions. Yet, our findings also suggested that this influence was insufficient to explain the difference in body weight due to smoking. We also assessed acute effects of nicotine on caloric intake, the other side of the energy balance equation, finding (contrary to common assumptions) that nicotine (and smoking) does not reduce eating behavior after a period of fasting but does enhance the satiating influence of recent food intake. This action would maintain satiety, or subjective “fullness,” longer after a meal (when smokers often enjoy smoking) and reduce between-meal snacking. The result could thereby lower caloric intake and help explain smokers’ lower body weight. We subsequently took this line of research in a clinical direction, with a goal of improving smoking cessation treatment. Dieting concurrent with trying to quit was shown ineffective by others, so we developed and tested an adjunct cognitive-behavioral therapy (CBT) tailored to reduce weight gain concerns, rather than weight gain itself, in women trying to quit. As hypothesized, this tailored CBT improved quit rates beyond that due to standard CBT, but a behavioral weight control adjunct (dieting) did not, consistent with other clinical and preclinical findings. We then tested this tailored CBT combined with bupropion (Zyban), finding greater quit rates at 6-month follow-up for this CBT vs. standard CBT among those receiving bupropion.
2. Chronic and Acute Tolerance to Nicotine: A hallmark of drug dependence is onset of tolerance to a drug’s effects (as noted in DSM-V), and little prior research had systematically examined chronic tolerance to nicotine in humans. This project established parameters of tolerance, including differences in responding to equal dosing between smokers and nonsmokers, the pattern across response domains, dose-response influences, and the time course of acute tolerance. Critically, our studies often obtained blood nicotine levels to correct responses for dispositional (pharmacokinetic) factors and clearly demonstrate functional (pharmacodynamic) tolerance. Results clearly supported chronic tolerance development with long-term smoking and suggested similar mechanisms responsible for both chronic and acute tolerance. Yet, our later lab studies questioned the close association of chronic tolerance with dependence, as tolerance was similar between dependent and nondependent smokers, only modestly declined long after cessation, and did not predict withdrawal or relapse after a quit attempt (although nicotine self-administration in the lab did predict both). Thus, tolerance may be important during onset of dependence, but tolerance no longer appears to index dependence after it is established; thus, its clinical utility as a criterion of dependence seems minimal.
3. Nicotine Discrimination: Drugs of abuse often have characteristic interoceptive stimulus effects, which may be related to their “subjective” (e.g. mood) effects and important in understanding the drug’s abuse liability and its mechanisms of action. Despite substantial preclinical research, no previous research had systematically examined nicotine discrimination in humans, probably owing to methodological limitations of existing dosing procedures. In this project, we established that humans could reliably discriminate nicotine’s interoceptive effects, that chronic tolerance to the effects did not appear to develop, and that discrimination behavior was influenced by training dose and nicotine pre-treatment. We then demonstrated that this behavior is centrally-mediated (the first such demonstration with any drugs in humans to our knowledge) and that the threshold dose for discriminating nicotine is very low in both smokers and nonsmokers. Other studies explored whether exposure to other drugs with nicotine could help explain their concurrent use, but neither alcohol nor caffeine altered nicotine’s discriminative, reinforcing, or subjective effects. Very recently, this line of research has examined nicotine discrimination via Spectrum research cigarettes varying in nicotine content.
4. Sex Differences in Nicotine Reinforcement: Little research prior to the 1990s examined sex differences in the acute effects of smoking behavior, and most researchers assumed either no differences or greater sensitivity to nicotine in women, given their greater preference for “light” brands. We conducted programmatic studies of sex differences in acute reinforcing and rewarding effects of nicotine and smoking, explicitly separating influences due to nicotine per se versus non-nicotine factors. Our research consistently found that women, relative to men, were less sensitive to manipulations of nicotine dose and more sensitive to non-nicotine stimuli from smoking. This difference was not seen for all effects (which would suggest dispositional differences) but primarily for self-administration or “rewarding” effects. Implications include the possibility that various sensory “substitutes” or other coping strategies may be of greater help, and nicotine replacement of less help, in women trying to quit smoking.
5. Screening Novel Medications for Smoking Cessation Efficacy: In the two general approaches to initial screening of compounds for evidence of cessation efficacy during the drug discovery process (e.g. FDA early Phase 2), acute lab studies of drug effects on symptoms generally lack validity while small clinical trials of quit success are valid but often impractical or under-powered. The high probability of negative results, unfortunately, in early testing of any novel drugs argues for a more efficient initial evaluation to inform whether or not to proceed to larger clinical trials. This project developed and validated a new procedure to optimally combine features of lab studies and small trials to take advantage of the experimental control and practicality of the former and clinical validity of the latter. Our innovative within-subject crossover design compares short-term quit attempts on active vs. placebo in a small sample of smokers already preparing to quit soon, those shown to be sensitive to a drug’s efficacy for cessation.
6. Reinforcement Enhancing effects of Nicotine: In our most recent project, we adapted procedures from preclinical research to clearly demonstrate, for the first time in humans, that nicotine enhances reinforcement from rewards unassociated with nicotine (or smoking). Small amounts of nicotine, including from non-smoked sources, may be sufficient for this effect, perhaps promoting lapse and relapse. Central to this effort was development and validation of a procedure to sensitively assess changes in the reinforcing value of a reward. Newer research examines these reinforcement enhancing effects due to nicotine via NRT. This research program was recently summarized in an overview (Perkins, Karelitz, & Boldry, 2017; see below).
