Heavy use for enough time will get you in a mist of passivity and poor memory. Every experienced weed smoker would have told you so much, a few years ago. Now there's a resistance to concede even that.
that's what I think of as well. however, many people will interpret "heavy user" as meaning like, someone who smokes a joint with any regularity at all. once a week might count as a heavy user by some definitions.
the disagreement on what counts as heavy use is really the problem here. what you're describing is someone who is basically high all the time. very little disagreement that being high on cannabis profoundly effects your concentration and memory while you're high. a lot of controversy and ambiguity about what happens the day after.

It isn't your most down-voted comment. It has -3 and you have about 10 other comments with lower scores. In the comment you solely mention the smell of kids. This doesn't mean that they are using cannabis at all. This could easily be similar to kids whose parents smoke cigarettes. Yes second hand smoke is bad for the kids over time, but that doesn't make them stoned by any means.
I don't disagree with you though that there are dogmatists around cannabis. There definitely are and they don't help anything.
My wife works at a low socio-economic status school. They're not using directly, no they're not stoned to the 'whoa, dude' level, it's more of a general 'grogginess' that kind of goes away late in the morning. It's definitely 'anec-data' of the finest sort, but it's something the teachers notice and comment on.
What I don't understand is why no one ever thinks that suddenly 'legalizing' a drug that produces a docile population is somehow more ominous than the previous gov't action to suppress it.
I ask mostly because I could have been that kid. I'm that adult. I smoke now, but my parents didn't and I didn't start while I was in school. My mother fought to get me awake for years: I wouldn't even wake up early for Santa Clause presents. Seriously, I chose to sleep and wait to open them until after we went to Grandma's house.
When we talk legalization on these sites it's usually from a middle class view of harmless recreation, but people who are irresponsible about other things aren't likely to be fastidious in their smoking habits either.
depends on what you're counting as "heavy use" and "enough time". also depends on whether or not you still smoke, and how much, and how often.
I don't disagree that there are some values for those parameters that do lead to "passivity and poor memory". we just don't really have a clear view on what the range of effects is across different values for those parameters, and how much variability there is within individuals. heavy use for one person might only be moderate use for another.
the resistance to conceding those obvious points is really just based on ambiguity. yeah, every experienced smoker is familiar with the cannabis haze. the questions are really more about the specifics than the generals.
My thoughts on it are that once or twice a week, single doses that intoxicate probably aren't that bad.
The issue is that there are some people who ingest cannabis not only on a daily basis, but throughout each of those days they are consistently ingesting it. I can't imagine this not having a detrimental effect, at least while they are using it this way.
Blanket statements are rarely correct.
