I was under the impression that psychoactive drugs such as lsd and marijuana caused short term memory loss and 'increased' our long term memory, I dident get much details so I'm not sure how a curate or the duration this effect is suppose to last (permanent or watever), though I believe there is some truth to it.
In my experience I have lost parts of my short term or at times all of it. And have always been real good at telling people about when i was a kid in great detail wile sitting around prophesying on lsd.
Anyone agree or have smiler story's to share with me, Thanks for the time!

Well psychedelics can surely stir up some old memories that you may have thought long lost. Additionally they have the tendency to make you pay attention to the details in things around you (in sober states) so perhaps in that respect, you're more busy making memories in paying attention to what's going on around you than just letting life pass you by.

Marijuana causes short-term memory loss, but that's only during the effects of the drug. Marijuana has not been proven to have any long-term effects on memory loss or any thing else really.

I know when I used to smoke pot daily I had some bad short term memory. I would forget deadlines for class and miss some HW. I never went to class high, but if we got assigned something and I would smoke afterwards, I would have a hard time remembering when it was due even after I sobered up. I had to really think about it, but within a week of quiting I noticed a huge difference in my memory. After a couple weeks it was like I had never smoked, I don't know about lsd though.

I def like they way Global said it. When compared to my gf (who only smokes cigs now and has tried dmt one night) i pick up on a lot more details in everyday life and see things that see says she would never give any thought to. and in this regard i could def see it possible that my brian is too busy noticing things than remembering.

but over all my memory is getting better even thought i smoke weed everyday. I do a lot of sudoko and other mind games to train my brain. idk if it helps but it sure feels like it, esp while high figuring out sudoko is very rewarding

the problem i have found with the short term memory loss theory is this. is you dont remember stuff and events in the shirt time then it never stuck with you and therefore you wont have that memory as a long term memory. this was something my dad said to me when i was younger and now that im older it really makes sense to me. but growing up i never had good memory either so ..... not really sure

What? I notice no negative effects on any mental capacity from spice use. I can't comment on mj because I do not use.

my memory is exceptionally good ,
but my imagination is even better

A fascinating read on the subject:
http://users.rcn.com/jki...ologyPages/M/Memory.html

Quoted from http://www.ncbi.nlm.nih.gov/pubmed/10821328 :
"Converging evidence suggests that the administration of 5-HT2A/2C or 5-HT4 receptor agonists or 5-HT1A or 5-HT3 and 5-HT1B receptor antagonists prevents memory impairment and facilitates learning in situations involving a high cognitive demand. In contrast, antagonists for 5-HT2A/2C and 5-HT4, or agonists for 5-HT1A or 5-HT3 and 5-HT1B generally have opposite effects."

That's an example of some receptor-specific findings, but still much is unknown with regard to how complex and intricate Serotonin's role is in memory and learning.

LSD is a very strong selective agonist of 5HT (Serotonin) 2A receptors. Anyone trying to claim LSD impairs memory and learning fuctions is spreading propaganda to claim the very opposite of reality. I know this to be fact from both published research and personal experience. Similar (but each a bit different ofc) activity is seen with other serotonergic drugs such as DMT, mescaline, psylocin, and 2c-b.

The opposite is true of DXM. Take a high enough dose, and it is neigh impossible to create new short-term memories until the effect of the DXM has worn off. Very difficult to focus, best of luck learning anything, but yet cognitive actions such as typing/writing/playing guitar are rather easy as long as you don't try to focus on what you're doing. Surely there's some type of feedback problem (much like the visual flanging of input that can happen similar to a TV-camcorder feedback loop) with hyperactive receptors responsible for short-term memory going on to explain that phenomenon.

Cannibinoid research has a long way to come in regard to marijuana's effect on memory. Substantial claims can be made that Cannabinoid effects on attention span (which no mj user can deny) is more to blame for a seemingly reduced short-term memory capacity. Ask any gamer who smokes pot - are they more skilled at real-time strategy games while stoned or not? Myself and all others I've talked to will say RTS skill comes easier while stoned, and strategizing in real-time requires a whole lot of short-term memory usage.

All that said, my memory these days is quite near what it should be. I have Celebrex to thank for my woes in this regard. Nasty stuff. Works wonders for ruptured disc inflammation, but completely not worth the risk of up to 8 years of short-term memory impairment. Several time frames spanning 12 to 24 months of complete sobriety with no memory improvement allow me to claim that the use of some aforementioned drugs have actually helped revert the memory effects from the NSAID.

I've often felt that when people think, "he's stoned, he's not paying attention", that it's not that he's not paying attention. It's not like he's some empty slate, drifting off. Most of the time, he's just paying attention to things that you're not paying attention to or what wouldn't be considered "acceptable" in society at the current moment to be paying attention to, and thus not in the intimate realm of conversation. But if you start talking about something that the stoner is interested in, then you can just wait and see how long his attention span is (I'm obviously projecting myself on this stoner )

I agree completely. The memory is still effective, the point of focus is just shifted off the normal path...

Concerning Cannabis and memory. http://www.youtube.com/watch?v=F7Qv8wmAlpc
5 part series on Cannabinoids that explains pretty much every thing.

He touches on how it affects memory, basically the more you can forget, the more you can learn.
People who lack proper Cannabinoid levels, usually are backward looking people (BLP) and always try to keep things in the past, while people who intake Cannabinoids are usually forward looking people (FLP) and tend to want to embrace the furture and not stay in old paradigms.

To find the 5th part you might have to dig on youtube for a sec.

Interesting Kronas, thanks i'll check that out

sometimes i think the flood of information into your senses and mind under the influence of these is so great that it seems to overload or strain your rational minds short-term memory.

But if your keeping your mind healthy and active while working with them as catalysts/allies in the right set/setting and consciously make an effort to be aware and grow in a positive way with them- then i think it can become much easier to pick up your train of thought once its lost; and, as terence said 'allow the mind to rove and scan in a more expansive type of way'. Things like this can open us up to these holistic states of barrier dissolution.. and the self and unconscious-including all long term memory-tend to brush up against each other in progressively more profound ways.

I haven't noticed any short-term memory problems in the long run, but i definitely think they have helped me make more connections with my long-term memory altogether. Leary believed that lsd decreased short term memory during the trip only, but that overall it increased long-term memory
