This part is not exactly true. For example a heroin addiction is going to have different features than a sex addiction.

There are significant elements that make something like heroin different than other addictions. Your body rapidly develops a chemical dependency on heroin. Many people become addicated after one use. Almost everyone that uses heroing a few times becomes addicted and treatment is extraordinarly difficult....so much so that another dangerous and long term damaging drug, methadone, is used to allow people to sorta function because they cannot completely end the addiction.

So something like heroin is different because it is chemical based as well as emotion and mental based. Unlike sex addiction which is entirely emotional/mental.
