Headshop owners who sell nitrous to obviously addicted people are generally not good citizens. I'd guess they make most of their profit from addicts like me. I only got cut off once after a 2wk/$10k run when I was almost too sick and incoherent to make a purchase. Every other store gladly kept selling to me when I was in that condition.
