Dopamine:opioids::Delusion:mindfulness?

This struck me as I was reading Your Brain on Porn. Dopamine is the seeking hormone, giving an illusion of pleasure by anticipation or imagination. Opioids are the real-life reward. I see a striking analogy with the Buddhist ideas of delusion and mindfulness. Delusional thoughts constantly displace us from present awareness into an imaginary future that never arrives. Coming back to mindfulness brings us into relaxed awareness of the present, and conscious pleasure in the physical senses. Stretching in the gym today, I was clearly aware of the pleasurable sensations in my joints and muscles. Ealier in the day I was walking around the campus where I work, appreciating the beauty of the sunlight on the buildings. I was fully present in my mind and all my senses. This is the complete opposite of the multiply distracted and confused state of porn use. Anyone else have any thoughts on this?
