Alcohol and drug use disorders are characterized by a combination of physical and psychological symptoms. People who suffer from substance use disorders are usually both physically and psychologically dependent, though it’s also possible to be physically dependent on a substance without being psychologically dependent, and vice versa.
Heroin, cocaine/crack, alcohol, and opiates/opioids as well as cigarettes are gonna be more physically addictive. Crystal meth is more psychologically addictive. Your book is going to say ecstasy, marijuana, mushrooms, and lsd are also psychologically addictive as well.
