How does drug addiction start?

Answer

Drug addiction begins with tolerance, you start to need more and more to get the same effects. You like the way they make you feel so you start taking more than recommended dosages or more of a street drug. Some drugs are physically addictive which means they actually change brain chemistry. An example is opiates, the brain makes natural opiates, when you abuse them your brain stops making them. When you try to quit you go through withdrawal symptoms it causes many uncomfortable sometimes painful physical symptoms
edit: There are also many emotional reasons for drug addiction such as depression, rejection ect. It is not a simple answer. There are usually multiple reasons that lead a person into drug addiction.


This is what i have to say:
Drug addiction can start off when you try a drug and as you keep using the drug, your brain will want more and more from it. Addictions get very serious later on and they also change the way you think, and they cause you lung cancer. Some people use these drugs to get away from problems, and some of the illegal drugs here in Canada make you feel tired. Drugs are never the best choice, and you shouldn't do drugs because your causing alot of harm to your body. Quitting is the most tough thing to do, especially if you have been doing it for some time. Its better to stay healthy then cause problems to your heart and every other system in your body.
