That's odd considering cannabis use was shown to decrease REM sleep and thus memory processing and consolidation.

#22Weed just makes you care less about completing the cognitive exercises of the exam.
Re: Association between cannabis use and subjective cognitive decline
#23A few thoughts after having read only the abstract: 1. The decline (which is reported to be less frequent in cannabis users) is self-reported subjective cognitive decline based on users’ experience. 2. I think that one of the hallmarks of cannabis use is an immediate decline in short-term memory. I believe this usually reverses itself after some time (hours or days). 3. I have used a lot of cannabis in the past. I st…
Yes, much has changed since the time of Dave.

Probably your last point is key. Even a little dab will do ya nowadays or you'll forget what I was talking about. Wait.
Re: Association between cannabis use and subjective cognitive decline
#24Subjective cognitive decline is a 'subjective' because it is perceived by the individual themselves. This means one of: 1) Weed dramatically reduces cognitive impairment. 2) Weed dramatically reduces an individual's ability to accurately asses their cognitive ability. 3) People who use weed are, for some other reason, dramatically less likely to suffer from cognitive impairment, or dramatically less able to accuratel…
From my personal experience, having several friends that have been smoking since high school up to now (mid 30s), it's definitely 2).
But maybe having friends who smoke weed dramatically reduces your ability to assess your friends' assessment of their own cognitive ability.

#25How does subjective decline correlate with objective decline, amongst stoners?

It’s likely 1.
Most adults are busy reducing brain cell count thru use of alcohol and other poisons. Marijuana on the other hand is proven to increase brain cell count thru neurogenesis in the hippocampus [1].
This is not possible for adults without marijuana [2].

I go with 4 for basically any study until it is verified independently. One big reason I tend to avoid science "news"

Another explanation is that weed smokers are less likely to self-report cognitive impairment, as that suggests it’s self-inflicted, which would cause feelings of regret and shame in many I suppose.

First: REM sleep etc. is not a proven cause-effect relation. Second: THC or some other compound might negatively affect that. Third: cognitive decline is broader than memory. Fourth: it was self-reported impression of cognitive decline.
I don't think there's reason to expect any relation between REM sleep and the outcome to hold.
