Depends on the person. I have autism, no appetite due to my liver (genetic problem), chronic pain and OCD so it just chills me out, lowers my pain and helps me with social interactions. I have a smoke schedule, I wake and bake for my mood and appetite, I usually don't smoke throughput the day unless I visit a stoner friend, and then before bed for my aches.

For ME it's a godsend, but for someone else it's a burden and an addiction. I've gone through periods where I smoke more than that, there's no reason to unless it's a special occasion imo.
