This is true for alcohol but I'm not sure about cannabis.
In California, a heavy indica is a recommended by doctors for sleep. My understanding is that it only affects R.E.M. sleeep.
Anecdotally, I track my sleep and when I smoked a heavy indica before bed I would consistently get at high 80 to 90% sleep quality. I'm on a couple of month tolerance break and have a hard time breaking 80% sleep quality.
