| If you look at the app and see that it says "better sleep"

| mood or felt better after that could be a placebo effect.
|
| You could check that by not looking at the app until after

|
| First, as far as I know, smoking weed would only affect your
| sleep if you consumed it a couple of hours or so before sleep
| (exact numbers vary per person, but you get the idea). If
| someone consumed some weed during lunch, I would expect theit
| nighttime sleep to be pretty much unaffected.
|
| Second, what do you mean by "sleep well"? They might fall
| asleep faster and stay asleep throughout the night. But how
| good was their sleep quality in reality? We are talking in
| terms of measuring REM cycle length and such.
|
| From anecdotal experience, I also thought that my sleep
| shortly after consuming was "good", as I would fall asleep
| easier. However, I can confirm that it wasn't high quality
| sleep at all for me, my REM cycle was very short, and I
| definitely noticed extra groginess after waking up (along
| with the rest of the things mentioned in sibling comments,
| like lack of dreams and such). Doing some more A/B testing on
| my sleep in regards to consumption of weed pretty much made
| it clear that it makes my sleep quality worse, but makes it
| easier to fall asleep.

|
| Sleep well, or "sleep enough hours"/"don't have insomnia"?
|
| Because sleeping well and REM sleep can't be deduced from the
| latter, it needs to be measured.
|
| Not even self-reporting is enough - because chronic bad sleep
| becomes the baseline, so people used it to just consider
| their mental clarity/energy levels when they wake up normal
| (like a person with shortsightedness, who doesn't know he has
| it -- they're then suprised when they finally get glasses and

| How I tell of increase in REM sleep (x):
|
| 1. Remembering some dreams in the morning. Especially that I

|
| 2. Calmer mood, less jittery, harder to irritate.
|
| 3. Easier to maintain focus on things that are not fun,
| easier to resist distractions.
|
| How I tell the level of cannabinoids/alcohol in the body fell
| enough to allow good sleep with both deep and REM phases: -
| The first night you sleep with a proper REM phase you get a
| REM sleep rebound. It's characterized by lot of vivid,
| intense, often rare dreams. Easy to notice after a period in
| which you pretty much don't remember any dreams. Happens
| because there is much pressure in the body to catch up for
| lost REM sleep, but rebounds are not enough to catch up.
|
| The sad and deeply diabolical thing about cannabis is that
| it's half time in body is quite long (though adapted bodies
| metabolize it faster), so smoking/consuming chronicly
| (defined in Huberman Lab as 2 times per week or more often)
| is enough to pretty much completely rob you of REM sleep. You
| can't remember any dreams and even worse, you loose your
| everyday free emotional therapist that is REM sleep. If you
| add some other negative experiences or just a difficult
| period in life, you're in for depression or at least
| sad/tired/boring days. And what you might escape into in
| these days? Often more weed.
|
| x: anecdotal, most likely influenced by huberman lab's
| episodes on marijuana and on sleep. They describe what roles
| both deep sleep and REM sleep perform. Episode on weed is a
| must - listen for people consuming cannabis in any form, even
| sporadically, because lot of things around cannabis are

| you thing problems with sleep affect you or that your sleep
| quality suffers because of drug (including alcohol) use,
| consider listening to these Huberman Lab episodes or talking
