It may not be drugs, it may be something else. Once you get used to it, it may be very hard to stop and the best way to overcome drug addiction is by having a mode of self determination.
We should know that the human body is an adaptable organism. So, when we keep taking or doing something everyday, we will get used to it. Our bodies will get used to it and it will be difficult to stop.
Do you even know what drugs do to the body? They damage some of our body systems. Sometimes, drugs may affect our liver, kidney or other notable parts of our bodies and this is why we have to stop. That can mostly be done with the intervention of God.
It is said that heaven helps those who help themselves. If you want God to help you on this journey of quitting drug addiction, you have to help yourself and how do you do that? You need to gradually detach yourself from that thing which is almost taking your life and with that, God will be in control.
Another thing is, I have a question for you. Are you familiar with what you are consuming? The drugs that you take, are you familiar of what they are being used for or what they are made of? I think that should be the first step. You have to read so you can be familiar with it.
And no matter how good a drug may be, it becomes very bad when you find yourself addicted to it. Thats because it will have to do a double work and will later damage your body system.
God will definitely help anyone who is on the journey of stopping drug addiction but be determined so that you can be helped.
