Furthermore, it raises the making of dopamine that regulates the feel a dearth of hankering and sets a coming to a stop in your typical UN useful dieting traditions.

Answer 1

It is reasonable to infer that this shared neurobiological quirk must play a role in explaining these substances’ more obvious common feature: that they all cause addiction. Although there remains controversy here, this idea is borne out by the evidence. By boosting dopamine levels, addictive drugs artificially stimulate the mesolimbic dopamine system, which has long been known to play an important role in motivation.

That is, they stimulate it directly, and not in the normal way via an experience that also gives rise to pleasure. (Compare getting someone to see stars by banging them on the head, rather than by showing them stars.) So to understand how drug addiction works, we need to understand what role dopamine plays in motivation.
