Bad habits like smoking, drinking and sniffing drugs is very hard to quit if you are addicted to it.

I has a customer last week that came to buy a phone with his two friends. Bros could not hold himself for just 15min to purchase a phone and go. After payment, two of them went outside the shop to smoke and came inside again. In this kind of situation, it is only God and their decision to completely stop it that will help him.

Staying away from an environment that does the bad habit and peer pressure can help you when making a decision to quit a bad habit. Good luck to you
