Key result
Current smoking (OR 5.2; 95% CI 3.6-7.5) and previous smoking (OR 4.5; 95% CI 3.1-6.5) were significantly associated with an increased risk of subarachnoid hemorrhage.

Smoking was associated with higher subarachnoid hemorrhage risk; extends prior observations but remains hypothesis-generating without prospective confirmation.

Do current smoking, previous smoking, and hypertension increase the risk of subarachnoid hemorrhage?
Odds Ratio: 5.2 (95% CI 3.6–7.5)
Both current and previous cigarette smoking, as well as hypertension, are strongly associated with an increased risk of subarachnoid hemorrhage, emphasizing the importance of early smoking abstinence.
Qureshi et al. (2001) conducted a case-control in Subarachnoid Hemorrhage (n=1,292). Cigarette smoking (current and previous) vs. Non-smokers was evaluated on Subarachnoid hemorrhage (OR 5.2, 95% CI 3.6-7.5). Current smoking (OR 5.2; 95% CI 3.6-7.5) and previous smoking (OR 4.5; 95% CI 3.1-6.5) were significantly associated with an increased risk of subarachnoid hemorrhage.
