Social smoking can lead to heart failure, warns study

Technology Nov 21, 2025

Think social smoking at parties is harmless? Evidence shows that even occasional cigarettes can seriously hurt your heart.
Just a few smokes here and there expose you to harmful chemicals, causing quick spikes in heart rate and blood pressure.
Over time, this adds up to real cardiovascular damage—even if you don't smoke every day.

Why it matters (even if you're not a regular smoker)

Social smoking can stiffen your arteries and make your heart work harder.
Nicotine messes with your heart's rhythm, raising the risk of conditions like atrial fibrillation that can lead to heart failure.
Plus, second-hand smoke at gatherings isn't any safer—it increases the risk of heart problems for everyone around.
Bottom line: even "just sometimes" isn't as safe as it sounds.
