It can also mean that. The "spaced out" part is key. I was always spaced out when I was a kid but it wasn't from drugs. I was regularly called a space cadet or something similar, especially by family.
Yes, the "in space, not here on earth" is key.
For anybody who is wondering why the "cadet" part is there (instead of just "spacey" or "spaced out") there was a popular TV show with comics, movies and novels about a "space cadet" in the 50's. Lots of 40's and 50's science fiction was about how wonderful space travel would be and about the colonization of space and "space cadets" were part of an elite group doing this. The 50's TV show, movies, comics etc. were based on a 40's novel that introduced the term "space cadet". At the time, in that sci-fi universe, "space cadet" was what was coming in the future after "astronaut".
My Dad and uncle (classic 50's nerds) enjoyed the Space Cadet series and spinoffs. Probably so did everybody else at the time with access to poular culture and a "nerdy" neurology. Non-nerds started using "space cadet" as an anti-nerd insult at the time to refer to (nerdy) people who enjoyed the series and to people whose minds were "in space" generally. Once the 50's ended, the knowledge that it used to be part of a pop culture phenom was lost and only the term remained.
All this info my Dad told me when I got into sci-fi in my own youth (the 70's) and he pointed me to the historical sci-fi. Nerds are frequently the parents of autists, as I am.
