One more reason to stop smoking - panic attacks
Don't panic -- stop smoking.
A new study suggests that panic attacks are far more likely in nicotine addicts than nonsmokers.
In surveying more than 3,000 Munich-area teenagers and young adults, researchers from Germany and California found that 7.6 percent of regular, nicotine-dependent smokers had a history of panic attacks.
That compares with 0.7 percent of nonsmokers, 2 percent of occasional smokers and 1.9 percent of regular smokers who weren't nicotine-dependent.
The scientists report a similar pattern for subjects who met diagnostic guidelines for panic disorder, a condition marked by recurrent panic attacks, fear about future attacks and worries about their consequences. A history of other psychiatric illnesses couldn't account for the associations, the researchers write this month in Archives of General Psychiatry. Four years later, nonsmokers were less likely than dependent smokers to have developed panic ills.
Here is an abstact of the study being discussed.

Background We examined prospectively determined bidirectional associations between smoking and panic and other anxiety disorders and their temporal ordering of onset in a representative community sample of adolescents and young adults.
Methods Baseline and 4-year follow-up data were used from the Early Developmental Stages of Psychopathology Study, a prospective longitudinal study of adolescents and young adults in Munich, Germany. We assessed smoking (occasional and regular), nicotine dependence, panic attacks, panic disorder, other anxiety disorders, and other mental disorders using the Munich-Composite International Diagnostic Interview.
Results At baseline, panic attacks and panic disorder were strongly associated with occasional and regular smoking and nicotine dependence (odds ratio [OR] range, 3.0-28.0). In the prospective analyses, we found increased risk for new onset of panic attacks with prior regular smoking (OR, 2.9; 95% confidence interval [CI], 1.0-8.4) and nicotine dependence (OR, 3.6; 95% CI, 1.2-10.5). Prior nicotine dependence increased also the risk for onset of panic disorder (OR, 3.3; 95% CI, 1.0-10.5), whereas preexisting panic was not associated with subsequent smoking or nicotine dependence. When using Cox regression with time-dependent covariates, prior nicotine dependence was confirmed to be related to subsequent panic attacks (hazard ratio, 2.7; 95% CI, 1.7-4.2), but not panic disorder (hazard ratio, 1.7; 95% CI, 0.7-3.9). Rather, we found indications that prior panic attacks/disorder might also have an effect on secondary development of nicotine dependence.
Conclusions In young adults, prospective analyses revealed a fairly unique and specific, unidirectional relationship between prior smoking and increased risk for subsequent panic attacks/disorder. However, we could not exclude the existence of a second, less frequent, reverse pathway of prior panic and secondary nicotine dependence.
