I get you're concentrating on me not listing every mechanism of directly effecting the biochemistry of the reward and reward prediction substrates in the brain.

I get you're concentrating on me not listing every mechanism of directly effecting the biochemistry of the reward and reward prediction substrates in the brain. But that doesn't matter. The distinction I'm trying to get across here is that normal stimuli that are just perceptions are not intrinsically addictive and when you claim one is there is a need for evidence of the claim.
