An addiction.
Substance abuse and addiction is called dependence. When a person is addicted to drugs or alcohol, they develop a physical and/or psychological dependence.
It is drug addiction.
An addiction?
Addiction can be a physical dependence. Physical addiction is not the only form of addiction. There is also psychological addiction, which is also considered addiction. A physical dependence and a psychological dependence often coincide with one another, but they don't always have to. Usually, psychological dependence comes first. One could be addicted to alcohol psychologically, meaning they have overwhelming desire to the point that it feels like a need to drink. Drinking too much alcohol on a regular basis can lead to a physical alcohol addiction, meaning the person has to drink alcohol for their body to function. The psychological addiction may even be gone at this point, and they not want to drink anymore, however the physical addiction is still there. Another example could be in marijuana. Marijuana can be very psychologically addictive, however it causes no physical addiction. Either way, an addiction is an addiction, be it physical, psychological, or both.
Withdrawal,Addiction, and Tolerance.
An uncontrollable dependence on a drug is known as addiction. This is a chronic condition characterized by compulsive drug seeking and use despite harmful consequences.

Tolerance to a drug (so that higher and higher amounts are needed in order to obtain the same initial effect) and dependence - both are part of the physical addiction. Psychological addiction does not involve physical tolerance and dependence, but can be difficult to treat, unless there is motivation to kick the habit.
