How do pheromones affect relationships? Does the usage of deodorant mask certain signals of the body to other people or ourselves?

Is there any evidence that these changes also happen in other areas? For example, would consistent cannabis consumption make my deadlift worse over time? To clarify, I don't mean consumption before/during the workout itself, just general consumption of > 2 times/week.
