I was always curious about the mental sharpness / memory portion. I know the short-term memory impairment is well documented but in regards to mental sharpness, that's a bit more nebulous and hard to hone in on. Is there any evidence that the use of cannabis effects cognitive ability while not under the effects or "high" of the drug?

I'm a former daily smoker. I carry a water bottle with me everywhere. When I was a daily smoker, I would pretty frequently forget where I had just set my water bottle down. My partner still gives me shit for it. Since stopping, this is a very rare occurrence.

As far as the mental sharpness thing goes,I didn't notice any major changes. Some people I know would have some fogginess the day after. This never affected me personally. I think brain fog is definitely a real thing for _some_ users.

I totally understand this is anecdotal. I'm just trying to share my experiences. I hate how defensive people can be about cannabis. I am sympathetic to this because giving proponents of cannabis prohibition anything to latch onto delays progress. It should be legal. People should also have honest discussions about it. It's a fairly low risk drug IMO, but it is a drug.

Speaking from personal experience (several years of nearly daily use with “off” periods of a few months) - the loss of sharpness was indeed a bit more nebulous but definitely real.

On the plus side, I recently discovered low THC, high CBD strains that offer the anti anxiety benefits without loss of sharpness or short term memory. There’s almost no psychoactive effect, so this won’t get you high, but it will chill you out and help you get in the zone if you struggle with anxiety or PTSD symptoms.

For me, it leaves a lingering effect on my short term memory and mental performance, that sometimes bleeds into the next day.

Long after the high wears off, I sometimes consciously can tell "wow, I am really mentally underperforming today".

It's more difficult to form quick/sharp responses when talking, my though process isn't as sharp, and its kind of like my brain has more difficulty following trees of connections that I am normally very quick at.

I think the worst change I made after I began regularly smoking was ceasing my regular workouts. I felt that I was making more intellectual and emotional progress with regular meditation while high than I was with my body during workouts, which I struggled with at the time for various reasons. My life has become much busier since I began smoking (much of which I positively attribute to the creativity I felt while smoking), and I haven't been able to get back into a regular workout schedule, despite not smoking often anymore. I am thinking now that the biggest detrimental impact on my memory and happiness came from losing my exercise routine more than the marijuana itself.

the pot doesn't have anything to do with you ceasing your workouts. the brasilian jiu-jitsu community has an incredible high # of regular users, while high.

It didn't make me stop exercising, no. I was dealing with some undiagnosed health issues that made my workouts exceptionally unproductive and chose to spend more time writing poetry, painting, and journaling while high instead of continuing my workouts. I felt I was making more personal progress with those than with exercise, and that being creative and productive was a better use of my time and energy.

After ending my five year exercise habit it became a lot harder to start exercising again, and brain fog and laziness began setting in. The highs also got a lot duller and less productive, and I subsequently began seeking the highs I knew from when I was in good health which led me down the wrong path for a while. I'm not blaming marijuana for this in any way, just acknowledging that I stopped exercising when I started smoking, and that some physical/mental health issues I've had since then most likely exist because I haven't been exercising.

In other words, putting psychoactive chemicals in your brain is a big deal and you should try to establish strong personal health and wellness routines before you begin doing it, and then prioritize those routines above the chemical habit.

Any daily pot-smoker will tell you that their short-term memory declines after a few weeks of daily/hourly use. It's extremely well known, though perhaps not well documented.

[nate_robo]

Right, I acknowledge that in my previous comment. I was more referring to the mental sharpness or cognitive ability. I was curious if there was a noticeable difference in critical thinking/problem solving for users while they are not under the effects of the drug itself

[thatcat]

The effects on memory are related to the time since you smoked and are most noticeable after 1-3 hours. Basically, you get stimulated at first (during which time you may actually have increased creative problem solving) and eventually you get tired or "burned out". It feels a lot like low blood sugar which is why some people over eat. If you smoke a lot these effects can linger as a sort of hang over. If you smoke every day for years, it might last a few days.

[superbaconman]

Speaking for myself. If smoking regularly yes, there's a decline, even 12 hours after the high has gone. The more I spread things out however, the greater the benefits seem to be, both during and after. Every couple of weeks would likely be most ideal.

As an unscientific experiment, compare the rate of spelling and grammar errors in the comments on this article to the error rate in HN comments overall. I think I see a pattern, but it may be that all I'm seeing is my own biases.

So, the phone's autocorrect is smoking?
