Buffering with a person

Hi there!
Can a person be like a drug? I think I have the same dopamine hit that Brooke describes when she talks about overdrinking, when I am with a friend with whom I have been kind of obsessed. I guess it is again my thoughts about this person, and what I think when he’s around, what brings the dopamine hit. Any tips on this? Same guidelines: allowing urges, protocol, etc?
