I assume you are speaking of a “drug addict” or “cigarette addict” who is seriously trying to quit, but they are going through serious bouts of “withdrawal.” I would also like to assume you are speaking of a believer in Christ (perhaps newly saved and desiring to be delivered from these former “vices”). In these cases, the Lord would surely share their desire to see them delivered from drugs or cigarettes, for He not only “saves the believing sinner from hell,” but He also “saves the believing sinner from being in bondage to sinful habits.” So, the question is, “Will the Lord take away their desire ‘in phases’ or will He take away their desire ‘immediately’?” I believe the Lord can and does deliver the believer from those desires (to do drugs or smoke cigarettes) immediately and thus they would not need the drugs or cigarettes to be delivered. I’m not saying their BODIES won’t still crave the drugs or cigarettes, but their MINDS would remain firm that they want the Lord to save them from these sinful habits and they would be given grace to refuse the drugs or cigarettes. In time, their “withdrawal pains” would subside and the BODY would also be delivered.

Before I cite some scriptures to support what I’m saying, I will offer a personal testimony. Before I was saved through faith in the Lord Jesus Christ, I was addicted to both drugs and cigarettes for at least 10 years. But I am happy to say that I was delivered IMMEDIATELY from drugs the moment I was saved (without any withdrawal whatsoever)! I praise God for this, and I give Him all the glory! Regarding cigarettes, I wasn’t convicted that this was bad habit until I was witnessing to my younger brother about his need of Christ. I was smoking at the time and he turned to me and said, “I really don’t think you should be talking about Jesus Christ and the salvation that He offers sinners with a cigarette in your hand.” The Lord used those words to convict me that I needed to be delivered from these as well, for if they would prevent anyone from listening to the gospel I needed to quit. By the grace of God, I prayed for deliverance and I haven’t smoked a cigarette since that day (in 1977), nor have I ever had the desire.

Now I will quote a passage that clearly teaches us that Jesus can and does “deliver believing sinners from the power of sin.” In John 8:30-32, 34, 36 we read, “As He (Jesus) spoke these words, many believed in Him. Then Jesus said to those Jews who believed Him, ‘If you abide in My word, you are My disciples indeed. And YOU SHALL KNOW THE TRUTH, THE TRUTH SHALL MAKE YOU FREE…Most assuredly, I say to you, whoever commits sin is slave of sin…Therefore if the Son MAKES YOU FREE, YOU SHALL BE FREE INDEED.” Notice, there is nothing in these words that would imply that the Lord delivers from sin “in phases”; rather it speaks of being delivered “once and for all.” I believe the words “You shall be FREE INDEED” support this view. These words of the Savior bring out “His DESIRE to set you free” and “His ABILITY to set you free” through the power of His Word. The Psalmist David spoke of this power in Psalm 119:11, “Your word have I hidden in my heart, that I MIGHT NOT SIN AGAINST YOU.”

Before I close, I do want to point out something from your question. You said, “Does God/Jesus USE SIN to help someone?” I can say emphatically that God would NEVER USE SIN to help anyone! God is absolutely HOLY (without sin) and the thought of Him “using sin” should never be entertained. Jesus was “God manifest in the flesh” (see 1^st Timothy 3:16) and it is said of Him that He “committed NO SIN” (1^st Peter 2:22); He “knew NO SIN” (2^nd Corinthians 5:21); and “in Him there is NO SIN” (1^st John 3:5). This means He “never sinned in thought, word or deed”; He never had any “experience of sinning”; and He never had a “sinful nature” that could tempt Him to commit sin. When He was tempted to sin by the Devil (see Matthew 4:1-11), it was “without (apart from) sin” (Hebrews 4:15), for there was NO SIN “in Him” to respond to his temptations (see John 14:30). Add to this the truth that when we are tempted to sin the Bible says, “Let no one say when he is tempted, ‘I am tempted by God’; for God cannot be tempted by evil, nor does He Himself tempt anyone” (James 1:13). This means Jesus (God) would never “use sin to help someone” who needs to be delivered from sin.  (472.1)  (DO)
