Question

what is one reason it may be harder for one person than another to quit nicotine use?
○ genetics
○ peer pressure
○ weight gain
○ celebrity use

Explanation:

To determine the reason why quitting nicotine is harder for one person than another, we analyze each option:

• Genetics: Genetic factors can influence how the brain responds to nicotine, affecting addiction susceptibility and difficulty in quitting. This is an inherent, individual - level biological factor that varies between people.
• Peer pressure: Peer pressure is more about external influence to start or continue using nicotine, not a reason for differing difficulty in quitting (it affects initiation more than the ability to quit).
• Weight gain: Weight gain is a potential side - effect of quitting nicotine, not a reason why one person would find it harder to quit than another (it's a consequence of quitting, not a pre - existing factor causing differential difficulty).
• Celebrity use: Celebrity use is a form of social influence on starting or perceiving nicotine use, not a factor in the difficulty of quitting for different individuals.
