There seems to be some cross tolerance, yes. I’ve never had an experience that would be worth the cost of coke while on pramipexole, at most i got a warm face and a sweaty forhead, it’s just wasted money.

I’ve also tried coke while not on any DA, and can’t say the same about that…

The study I’m thinking of tried it to relieve the urge on recovering addicts, with what I remember pretty good results.
