“…In 1330 twins (aged 14‐22 years), early‐onset regular tobacco use was associated with increased risk for intentional self‐injury at age 22 (AOR = 4.6 [95% CI = 1.9‐10.8]) 20 . In adolescents, daily cigarette smoking is associated with current suicidal ideation; CPD had linear relationships to future intentional self‐injury (AOR = 4.5 [95% CI = 2.0‐9.7]) and suicidal behavior (AOR = 2.1 [95% CI = 1.1‐4.1]), controlling for depression and alcohol or other substance‐use disorders, 101 underscoring the potential importance of preventing early smoking.…”

Alcohol or other substance‐use disorders 10,15,22,23,35,100 or psychiatric disorders 15,54,58,101 do not generally account for reported associations between smoking and suicide.

Background and Objectives Extensive evidence links smoking and suicide independently of psychiatric diagnoses, but there are questions about the pathophysiology and specificity of this relationship. We examined characteristics of this linkage to identify potential transdiagnostic mechanisms in suicide and its prevention. Methods We reviewed literature that associated suicide with smoking and e‐cigarettes, including the temporal sequence of smoking and suicide risk and their shared behavioral risk factors of sensitization and impulsivity. Results Smoking is associated with increased suicide across psychiatric diagnoses and in the general population, proportionately to the number of cigarettes smoked per day. Rapid nicotine uptake into the brain through inhalation of conventional cigarettes, electronic cigarettes (e‐cigarette), or even second‐hand smoke can facilitate long‐term sensitization and short‐term impulsivity. Both impair action regulation and predispose to negative affect, continued smoking, and suicidal behavior. Intermittent hypoxia, induced by cigarettes or e‐cigarettes, synergistically promotes impulsivity and sensitization, exacerbating suicidality. Two other shared behavioral risks also develop negative urgency (combined impulsivity and negative affect) and cross‐sensitization to stressors or to other addictive stimuli. Finally, early smoking onset, promoted by e‐cigarettes in never‐smokers, increases subsequent suicide risk. Conclusion and Scientific Significance Prevention or cessation of nicotine inhalation can strategically prevent suicidality and other potentially lethal behavior regardless of psychiatric diagnoses. Medications for reducing smoking and suicidality, especially in younger smokers, should consider the neurobehavioral mechanisms for acute impulsivity and longer‐term sensitization, potentially modulated more effectively through glutamate antagonism rather than nicotine substitution.

“…Sathian et al found a dose-response relationship between the average number of cigarettes smoked during the week and the presence of suicidal ideation in young adults [ 79 ]. Waters et al found an association between smoking and suicidal ideation among college students independent of substance or alcohol abuse and major depressive disorders [ 80 ]. Therefore, primary preventive programs to prevent students start smoking and smoking cessation interventions may also be beneficial in reducing the prevalence of suicidal ideation among students.…”

Objectives. This study is aimed at comparing the prevalence of suicidal ideation among Iranian medical, dental, and pharmacy students and determining the demographic and basic characteristics and mental and psychological issues associated with suicidal ideation in these students. Methods. This cross-sectional online survey was conducted during the 2020-2021 academic year on medical, dental, and pharmacy students studying at the Tehran University of Medical Sciences (TUMS). The questionnaire consisted of six sections: Beck Hopelessness Scale (BHS), General Health Questionnaire (GHQ), Perceived Stress Scale (PSS), UCLA loneliness scale, Maslach Burnout Inventory-Student Survey (MBI-SS), and a questionnaire that was designed to evaluate students’ family history, current psychological status, and basic and demographic characteristics. Results. In total, 419 students participated in our study, with 133 (31.7%) being medical students, 85 (20.3%) being pharmacy students, and 201 (48%) being dental students. In our study, the prevalence of suicidal ideation was 32%. Family history of psychological issues ( OR = 2.186 , P =0.012), current or past smoking ( OR = 2.155 , P = 0.01 ), parents not living together ( OR = 2.512 , P = 0.046 ), and satisfaction with the current field ( OR = 0.51 , P < 0.001 ) were all independently associated with the presence of suicidal ideation. Also, higher scores in BHS ( OR = 1.167 , P < 0.001 ), PSS ( OR = 1.081 , P = 0.001 ), and UCLA loneliness scale ( OR = 1.057 , P < 0.001 ) were independently associated with a higher risk of suicidal ideation. Conclusion. The prevalence of suicidal ideation among Iranian medical, dental, and pharmacy students is relatively high and has increased during recent years, which needs emergent action.

“…As a result of the significant social demands and changes in lifestyles and learning styles, college students are more likely to experience mental problems, including suicidal ideation. Multiple studies have shown a high prevalence of suicidal ideation among college students [ 13 , 14 , 15 , 16 ]. It is well-known that suicidal ideation is related to various factors, including mental disorders, physical illnesses, and biological, psychosocial, and environmental factors [ 17 , 18 , 19 , 20 ].…”

Objective: The objective of this study was to explore the relationship between extracurricular activities, stress, and suicidal ideation and to examine the mediating effect of stress between extracurricular activities and suicidal ideation in Chinese college students. Method: A total of 6446 college students were surveyed with a web-based online data collection system using the self-made demographic questionnaire, Suicidal Behaviors Questionnaire—Revised (SBQ-R), and the 21-Item Depression Anxiety Stress Scales (DASS-21). SPSS 24.0 was used for descriptive statistics and correlation analysis, and the bootstrap method in the process procedure for SPSS Version 3.4.1 was used to construct the mediating effect model. Results: Gender, school grades, living area, and family income status were influencing factors for suicidal ideation, stress, and extracurricular activities. Extracurricular activities were negatively correlated with stress (r = −0.083, p < 0.001) and suicidal ideation (r = −0.039, p < 0.01). Extracurricular activities had no direct predictive effect on college students’ suicidal ideation (c = −0.198, CI: −0.418, 0.023), while stress had a mediating effect between extracurricular activities and suicidal ideation; the indirect mediating effect was 0.159. Conclusions: Extracurricular activities indirectly predict college students’ suicidal ideation through stress. A variety of extracurricular activities can decrease the stress and suicidal ideation of college students and benefit their mental health.
