Anecdotally, I've noticed with friends and acquaintances that this leads to what basically comes down to a de-motivating effect, i.e. the "reward" via built-in mechanisms (like productivity, exercise, etc) gets attenuated over time as marijuana activates similar reward mechanisms very quickly and reliably via something as simple as inhaling. Basically "why bother going for a run, smoking makes me feel even better and I don't have to do anything".
I don't want to seem critical or anything of the sort, I've just seen it myself in multiple cases and it "makes sense" to me.
Your anecdote seems to counter this. Do you find the effectiveness of this strategy reduces over time?
That said it's obvious daily drinking has similar reward system impact with significantly greater overall health consequences.
An indica can put me into a lethargic state while a good sativa gives me as much energy as a cup of coffee but provides 2-4x the head rush.
I will frequently hit a sativa vape before going on a run or doing chores because it makes it a more pleasant experience with no downsides. If I were to swap to an indica it would not be enjoyable whatsoever.
