There is no single element that can indicate whether or not a person would get addicted to drugs. Addiction risk is influenced by a mix of genetic, environmental, and developmental variables. The more risk factors a person possesses, the more likely it is that drug use will lead to addiction.
Another piece of good news is that drug usage and addiction may be avoided. Teachers, parents, and health-care providers all play important roles in teaching children and avoiding drug use and addiction.
                
 
If you use opioids to deal with pain on a normal basis, you run the threat of developing a resistance to them and also possibly ending up being physically reliant on them. This does not indicate that you have a dependency issue. Only a tiny portion of individuals will develop a dependency to opioids also when they are administered suitably and also under the supervision of a medical professional.
 
Your brain adjusts to the extra dopamine gradually. To feel the same great feeling, you might need to take more dopamine. Other pleasures, like food and time spent with family, could also be less enjoyable.
The effects of long-term drug use can affect other brain chemical systems and circuits. They can impact your:Judgment. Decision-making. Memory. Ability to Learn. These brain changes can all lead to brain changes that make it more likely you will seek out and use drugs in ways not under your control. 
                                            
                                             
Relapses are not unusual. However, it does not mean that therapy failed. The treatment for chronic conditions should continue and be modified based on the patient's reaction. The same applies to other chronic diseases. It is important to regularly review treatment plans and adjust them to keep up with changing patient needs.
What changes does a person's brain experience when they use drugs?
Most drugs affect the "reward circuit" of the brain. This results in pleasure and floods the brain's chemical messenger dopamine. A functioning reward system encourages people to do the things that are necessary to thrive, such as eating well and spending time with their loved ones. Dopamine surges in the reward circuit can cause people to reinforce harmful but enjoyable behaviours, such as drug abuse. This encourages people to continue engaging in the activity. 
  
Your brain adapts over time to the added dopamine. The substance might be more concentrated to achieve the same effects. The enjoyment of other activities such as eating and spending family time can be reduced.
A prolonged period of drug abuse can lead to brain changes and other brain chemical pathways. These drugs can cause problems in your judgment, decision-making ability, memory, learning capacity, and even your ability to learn. These mental changes could lead you to use drugs in ways you are not able to control.
                                             
Aside from physical dependence and tolerance, addiction is also distinct from addiction. If you stop using a substance abruptly after becoming physically dependent on the drug, you may experience withdrawal symptoms. A tolerance is a condition where a drug's effectiveness declines over time.
To illustrate, opioids can lead to dependence and tolerance. This doesn't necessarily mean you have a dependence problem. Only a few people will ever become dependent on opioids even if they have been prescribed by a qualified doctor.
Your brain is programmed for you to want to find similar situations to those that make it feel good. To keep you motivated, repeat these acts often. 
Physical dependency and tolerance do not necessarily mean addiction. You may feel withdrawal symptoms if you abruptly stop using a drug, after becoming physically dependent. When a drug's effectiveness is reduced over time, it can cause tolerance.
If you take opioids for pain relief, you might develop a tolerance and become dependent. However, this doesn't necessarily mean you are unable to depend on certain things. Even if opioids are prescribed correctly and monitored by a doctor, only a small percentage of people will become addicted to them.
