I get that, my roommate is an ex coke dealer, and I was one of the only people they'd do coke with because I just don't get addicted to stimulants (besides the almighty nicotine). I'd actively slow them down, they knew I wasn't just hanging out for coke. I'd also occasionally buy a little bit off them just to keep the split fair. I would love to just get like a dose or two of a stimulant to fuck with for a bit, just don't really ever want to pay for it because I don't care for it more than a casual thing.
