Which area in the body is not affected by smoking cigarettes?
a)brain
b) lungs
c) lymph system
d) stomach

Brain cause when u spoke it effects ur stomach so that is the brain that is not effective

( D)

When you smoke cigarettes the brain develops extra nicotine receptors to accommodate the large does of nicotine.

Obviously cigarettes can hurt hurt your lungs and clog them up.

Cigarettes do hurt your lymph system.

While you might get bad heart burn and Gerd, your stomach is naturally protected by the acid it makes to break down food.

So, while cigarettes do harm your body and can be just as addictive as heroine ( that was crazy to me ) in this case your stomach would be the least harmed. Hope this helps you
