Students need to study about that so they don't become addicts themselves
Addiction is not a solid topic. It has grey area - What is addiction? Is it physical or psychological need? Some matters can be a tricky topic in general, seeing as everyone experiences the world in their own way.
Addiction!
There really are no needs met. Some people just think it will relieve them of stress or make their lives much easier. Please don't do drugs. It will come back to bite you. ;)

Drug Addiction: How do I help a cocaine continous user?
Whether or not you need to stay overnight for drug addiction treatment would depend on where you are seeking treatment and what type of drug you are addicted to. If you are on heroin for example you would need to stay not just over night but a full 30 to possibly 90 days.

Addiction is caused by changes brought about in the brain by drug use, which cause the individual to need the drug in order to function. "Allergy" was the explanation used in the mid-20th Century, when we knew much less about addiction than we know today. While there is some genetic predisposition to addiction -- especially to alcohol -- addiction does not qualify as an allergy, which is an abnormal response of the immune system with an entirely different mechanism.
Possible to study at home, but you benefit from meeting fellow students, plus teachers, in a college
