To explain, taking dopamine directly does not have an effect on the center, but it can be caused by taking other substances to make the center produce dopamine.
The first product was absorbed by the stomach and intestines, and the effect of action was delayed, and the dose was not as high as later. Addiction is not as severe as it was later.

No, dopamine doesn't cause destruction. The composition of drugs is different from the original substances of the human body, but some of them are chemically similar, and the result is irreversible damage to the receptors. Drug addiction cannot be stopped, even if it survives the initial negative feedback collapse, it is still disabled.
