Xpost from R/Cocaine because I think I'll get more scientifically researched answers here but more personally researched information there 😂

Logically, it seems like there is likely a point of diminishing returns where doing another line doesn't get much of an effect. Is the limiting factor creating this situation your dopamine?

If you actually can, anybody know how many (average sized) lines it takes to get to this point of diminishing returns in one evening for a new user or someone that hasn't done it long enough to be like a new user again?

Also, how many days does it take for your receptors to go back to normal after the down regulation from one evening as described above?
