Background Epidemiologic studies have provided inconsistent results on the association of cigarette smoking with the incidence of amyotrophic lateral sclerosis (ALS). To summarise published evidence and explore sources of heterogeneity, we conducted a systematic review and meta-analysis of studies that evaluated this association. Methods Published studies evaluating the association of smoking with incidence of ALS were searched in bibliographic databases, with relevant information collected… 
Association of smoking with amyotrophic lateral sclerosis risk and survival in men and women: a prospective study
TLDR
In this large population-based study, smoking was associated with ALS risk and worse survival in women but not in men, and old age and female sex were associated with lower survival.
Population-based study of environmental/occupational lead exposure and amyotrophic lateral sclerosis: a systematic review and meta-analysis
TLDR
It is indicated that environmental/occupational lead exposure was positively proportional to the risk of ALS.
Association between alcohol consumption and amyotrophic lateral sclerosis: a meta-analysis of five observational studies
TLDR
Alcohol consumption reduced the risk of developing Amyotrophic lateral sclerosis compared with non-drinking, and has a potentially neuroprotective effect on the development of amyotrophicateral sclerosis.
Environmental Risk Factors and Amyotrophic Lateral Sclerosis: An Umbrella Review and Critical Assessment of Current Evidence from Systematic Reviews and Meta-Analyses of Observational Studies
TLDR
A small number of published meta-analyses on environmental factors and risk of ALS was identified, a phenomenon that could be attributed to the challenges in studying a rare neurological disease.
Smoking, alcohol consumption, and the risk of amyotrophic lateral sclerosis: a population-based study.
TLDR
It is indicated that current smoking is associated with an increased risk of ALS, as well as a worse prognosis, and alcohol consumption is related with a reduced risk ofALS, further corroborating the role of lifestyle factors in the pathogenesis of ALS.
Contribution Smoking , Alcohol Consumption , and the Risk of Amyotrophic Lateral Sclerosis : A Population-based Study
Smoking has been posited as a possible risk factor for amyotrophic lateral sclerosis (ALS), but large population-based studies of patients with incident disease are still needed. The authors
Population-based study of amyotrophic lateral sclerosis and occupational lead exposure in Denmark
TLDR
An association between consistently higher occupational Pb exposures and ALS is indicated, which support those of previously reported associations between ALS and specific occupations that commonly experience Pb exposure.
Relationship between smoking and ALS: Mendelian randomisation interrogation of causality
TLDR
There was no strong evidence for a causal or reverse causal relationship between smoking and ALS and other smoking phenotypes, such as current smoking, may be suitable for future Mendelian randomisation studies.
Amyotrophic Lateral Sclerosis and the Military: A Population-based Study in the Danish Registries
TLDR
In this large population-based case–control study in Denmark, employment by the military is associated with increased rates of ALS, consistent with earlier findings that military service or employment may entail exposure to risk factors for ALS.
Physical Trauma and Amyotrophic Lateral Sclerosis: A Population-Based Study Using Danish National Registries.
TLDR
The data suggest that physical trauma at earlier ages is associated with ALS risk, and age at first trauma could help explain discrepancies in results of past studies of trauma and ALS.

Prospective study of cigarette smoking and amyotrophic lateral sclerosis.
TLDR
Limited evidence is provided that current cigarette smoking may be associated with increased death rates from ALS in women but not in men, and the difference in the relative risk estimates between the sexes was statistically significant.
Smoking, Snuff Dipping and the Risk of Amyotrophic Lateral Sclerosis – A Prospective Cohort Study
TLDR
This study provides no evidence that smoking or snuff dipping is associated with an increased ALS risk among men, and further stratified analyses of smoking status or types of tobacco smoking did not reveal any excess risks in any strata.
Lifestyle factors and risk of amyotrophic lateral sclerosis: a case-control study in Japan.
TLDR
Vigorous physical activity, self reported stress, a type A behavior pattern, and less frequent intakes of green-yellow vegetables were significantly associated with increased risk of ALS, whereas smoking and drinking habits were not.
Association of Cigarette Smoking with Amyotrophic Lateral Sclerosis
TLDR
The relationship between amyotrophic lateral sclerosis and cigarette smoking in a case-control study conducted in New England from 1993 to 1996 was explored, and the weak relationship of ALS with alcohol use was apparently due to confounding by smoking.
Prospective study of chemical exposures and amyotrophic lateral sclerosis
TLDR
Evidence was found, suggesting an increased risk of ALS with formaldehyde exposure, and this result is unlikely to be due to bias, but should nevertheless be interpreted cautiously and needs to be verified independently.
Population-based case-control study of amyotrophic lateral sclerosis in western Washington State. I. Cigarette smoking and alcohol consumption.
TLDR
The finding that cigarette smoking is a risk factor for ALS is consistent with current etiologic theories that implicate environmental chemicals and oxidative stress in the pathogenesis of ALS.
Population-based case-control study of amyotrophic lateral sclerosis in western Washington State. II. Diet.
TLDR
A positive association with glutamate intake is consistent with the etiologic theory that implicates glutamate excitotoxicity in the pathogenesis of ALS, whereas the associations with fat and fiber intake warrant further study and biologic explanation.
An Evidence-Based Medicine Approach to the Evaluation of the Role of Exogenous Risk Factors in Sporadic Amyotrophic Lateral Sclerosis
TLDR
Evidence supported the conclusion that the following were probably not risk factors for ALS: trauma, physical activity, residence in rural areas and alcohol consumption, and evidence in support of smoking being a probable (‘more likely than not’) risk factor for ALS.
