The Takeaway
Breaking any habit can be difficult. If you want to quit smoking you’ll have to be completely resolute in your new routine, and need to be strong when it matters most – especially when you experience strong cravings, or even if you happen to relapse.
Long-time smokers will battle a stronger addiction than others, but the immediate and long term benefits are more than worth the trouble.
