Can you grieve a drug

I was going back home from a night out with some friends, and I drove past some of the places we used to go to. I know that the relationship was unhealthy and codependent, and it was really intense like a drug. But at the same time I wonder if I can grieve losing that drug. Like the thought of cuddling her, or watching TV while she lays on my chest and gently falls asleep. Her falling asleep on the car trip back.
