Another good thing is that people can avoid using drugs and getting hooked on them. Research funded by NIDA has shown that drug use and addiction can be stopped or lessened with programmes that involve families, schools, communities, and the media. Trends in drug use are affected by both personal and cultural factors. However, when young people see drug use as harmful, they tend to cut back on it. So, education and outreach are the best ways to help people understand the risks of using drugs. Teachers, parents, and people who work in health care all play important roles in educating young people and stopping them from using drugs and becoming addicted to them.
Things to keep in mind: Addiction to drugs is a long-term disease that causes people to want to use drugs and use them even though they know it's bad for them.
                
 
Biology. The genes passed down from parents determine around half of a person's proclivity for addiction. Gender, race, and the presence of other mental issues are all factors that may raise the chance of drug usage and addiction.
 
Biology. Half of the risk of addiction can be attributed to genes passed on from parents. Other variables that could increase your chances of drug addiction include gender, race, and other mental disorders.
Biology. About half of an individual's chance of addiction is determined by the genes they are born with. Risk factors for addiction and drug use include gender, race, and other mental disorders.
Environment. Environment can include many factors. These include family, friends, economic status and quality of life. Peer pressure, sexual and physical abuse, early exposure to drugs and stress, parental supervision, and peer pressure all increase the likelihood of a person becoming addicted. 
                                            
                                             
The following signs and symptoms are indicative of addiction: A strong desire to consume the drug frequently, perhaps many times each day. The substance is consumed in greater quantities than you originally intended and for longer periods of time. Even if finances don't allow it, ensure you always have the prescription handy. You may use drugs even though they are harmful to your health or make you irrational with loved ones. Spending more alone time. You can blame your personal hygiene for things like lying, theft, and engaging in dangerous behaviours such as driving under influence of drugs, or engaging with unsafe sexual activities. The majority of your time is spent on obtaining, using or recovering from the drug’s effects. Nilginess is one side effect of quitting smoking. 
  
Relapses are common but don't necessarily mean the therapy failed. Long-term treatment should be continued and modified based on the patient's response. This applies to other long-term conditions. It is important to review treatment plans often and to adjust them as the patient's needs change.
What kind of changes does drug use cause to the brain?
                                             
Most medications work by stimulating the reward circuit of the brain with the chemical messenger dopamine. Dopamine reward circuit surges encourage people to engage again in harmful, but enjoyable, behaviours. 
There are ways people can stop using drugs or becoming addicted. All three have a responsibility to educate young people, including teachers and doctors, about how to stop using drugs and become addicted.
What does it really mean to be addicted? Addiction is a mental illness that affects both the brain as well as the way one acts. Someone addicted to drugs will not stop wanting to use drugs, regardless of how harmful they are. It is more likely that someone will get help for their drug addiction sooner than later.
