^I sleep better when I smoke daily. I quit smoking daily a few years ago, now I smoke rarely. Back when I smoked daily, I remember clearly that I couldn't go to sleep RIGHT after smoking (unless there were opiates in play, but that's a different story..), but about 30 minutes after smoking a spliff my high would always diminish in 'intensity', and I'd become a little drowsy and quite sleepy. I would always be able to just drift off to sleep with the greatest ease during that moment.. So yeah, I did sleep more, and had less trouble falling asleep when I still smoked weed every day. Though I have to say, if I get a full night's sleep (6-8hrs - unfortunately that's rare for me, but again this has to do with opiate-abuse and benzo-use) now that I don't smoke weed anymore, I feel far more rested than I used to from sleeping the same amount of time whilst falling asleep under the influence of weed.
So yeah, I fell asleep a lot easier/faster as a daily pot-smoker (just not immediately after smoking but ~30 mins after. Despite falling asleep being harder, the quality of my sleep is significantly better when I don't smoke pot. I remember it was just a given that I used to be pretty tired during the day when I was a stoner, and I mean I was tired already before I started getting stoned for that day. I got 6-8 hours/night every night easily back then. Now if I sleep 6 hours I'm well rested and I don't get tired during the day.
