A side effect of LSD : the trailing phenomenon

[slurplesAlice]

i also have hppd and mines probably 8 as well

[OliverWhalen]

Mine is an 8 constantly due to HPPD... Literally all the time. The strange thing is that the tracers, or "trails" are the least of my problems. Anyone who has used psychedelics will know the visual pseudo-hallucinations that I am talking about. It is a rare condition, and in my case was brought on by long term abuse of psychedelics (specifically 2C-E, MDMA, LSD, and DMT). However, HPPD or being "perma-fried" is a very real thing. I do not condone use, but if you do use, at least start small!!!

[ghoffman701]

after several viewings- and it having been probably 40 yrs since i experienced the effect- i would have to say #9.it was more of a transparent neon like rainbow slow moving effect. and probably one of the best and few overall pleasant things of the experience.i still remember it tho it isnt something that you ever forget. kinda like seeing the northern lites it stays with you! cool video btw.

[HAHAHAHAIMTBOY91]

I would say for me it was 10 at the start of it metabolizing, then 8, followed by 4. Then it went back to 10. Might I say, Men In Black on acid... is fucking mind blowing.

[mtndewman3000]

Ha ha I see that everyday. This has been happening to me for about two months and I went to see a euro ophthalmologist about it and he said that it's "palinopsia" and it might or might not go away. I'm supposed to go back in six months to see if it actually goes away lol.

[TheBillyGtube]

It depended on how good the acid was.

[MrAjh420]

took couple of hits lsd night , theres a resurgence of Lsd where i live , its all over the place , and i love it!

[CorpseResurrector]

What are the mathematical algorithms used to produce this video?

[CorpseResurrector]

0: no trails.

[whateva1983]

None of them fits my experience. The one that does better is the last one. What I see is an after image, not multiple copies of the same thing. Is pretty much the trail that you see normally when something is moving really fast, only that with lsd you don't need to go that fast.

[Cmm333]

number 9 (y) the trails all seem like they're one, in all the other ones you see seperate images of the same image in the trail, which isnt what its like.. it flows fluently and less in focus, your mostly only concentrating on the object not the trail anyway

[theartfulbadger1]

Mine look most like number 9, although more fluid. Less like a discreet series of after images, and more like a continuous blur.

Also, the matlab program is brilliant - you can see some really beautiful parabolas traced out by the football. [9.8 m s^-2]

[dirtmanwashere]

@theartfulbadger1 yeah mine too. you described it.

[SuperRama666]

nice how did you achive this effect plz let me know thanks in advance

[JaemSolitude]

@SuperRama666 is normally after the one hit arround 2-3 hours after taking it jut gotta make sure everything behind is still

[sipsaki]

I experience Palinopsia, seeing trail which from what I've heard is much like a LSD trip, So I agree with FUBARsince1990, everything have tracers but #9 and 10 was pretty close but no cigar.... :0)

[GMTaelin]

Yep none resembles my experience. It does resemble the trails I had on LSD, though wrongly (the trails already start 80% transparent, not 100% visible). But the afterimages I got daily are different.

[slashedmckagan]

@GMTaelin what do you mean by daily after images? like flash backs? im debating doing acid and this is the one thng that is worrying me

[FUBARsince1990]

i would say video 9 reminds me most of trippin

[moloko5]

@FUBARsince1990 I agree... number 9, except everything has tracers not just the one object

[goondropapill]

The trails are too sharp, they need to be smooth if you get what I mean.

[bengolfen11]

haven't dropped acid in 30 years (maybe 4x only) but have awoken into the present moment with very little internal dialogue (reduced arising of thoughts) that i see trails all the time....

[cookiethewaitress]

You should standardize the images. The different kinds of activity make it more entertaining to watch but take away from the decision, lowering the internal validity of your study. It looks like your variables are trail length and time, subtle differences that can be confounded by changes in distance and screen composition. I like what you're doing though, I never would have thought trails needed to be examined.

[WhoKilledET91]

It all depends on dosage, lower doses the trails aren't so bad like movie 9. Higher doses have some mad trails

[andrespereyda]

7 hits the spot for me, but the acid trip can vary and have low frame-rate trails on top of regular trails, or at least you can get lost in the trails. it becomes like a sea of hallucinations, undulating color, and other things, morphing.

[alkalinemuse]

I have this, but not due to LSD (I've never taken it). It's constant though, it's there all day and night. It's not quite as severe as the examples in your vid though.

[billyeason73]

9 was probably the closest, but still too much like a strobe effect. LSD trails are more blurry and faded.

[jnh2opolo5]

the best way to know is for you scientists to just try it. although i would recomend Psilocybin, rather than LSD. My reasons for this?

Psilocybin (Magic Mushrooms "shrooms") has better effects on colors becoming more vibrant and trails apearing. from my expierience with LSD (ACID) the atmosphere always seemed more stagnant and the walls that a "breathing" motion to them. trails can be seen in both, but its just that mushrooms typically have better consistancy when you want to see "trails."

[jnh2opolo5]

@jnh2opolo5 Plus one can most likely trust the product of Psilocybin containing mushrooms much more than a street dealers acid. But then again, i'm sure that you boys n gals with PHD's would have no "intellectual problem" with knowing how to make said substances. although the legal implications of cultivating and producing are worse than posesing.

either way....somewhere in between videos 8 and 9 for me. but you need to look at this from a mathematical point of view.

think in the terms

[jnh2opolo5]

@jnh2opolo5 of an exponential function. [Y=A(B)^X] Where "Y" is the opacity of the trail after "X" ammount of time. When "A" Is the visibility of your hands trail begining at (0,100) and "B" is the rate of decay (Meaning growing in transparency, or your hands trail becomes more transparent as eash interval of "X" Passes) I would say its about Y=100(0.40)^X.....X=time in seconds, Y=Transparency of visual trail, A=100% hand visibility at begining of trail at zero seconds, & B=after every

[jnh2opolo5]

@jnh2opolo5 interval of X, the value of A will be 40% of its original ammount (Will have decayed by 60%)........

Of course there are other factors that come into play here such as the ammount of LSD or psilocybin ingested (meaning if the doesage is unknown, whether or not the substance reached the correct level of concentration within the CNS to produce phychoactive effects.) will surely determine the rate of decay. Also, other factors like individual serotonin levels and concentration of

[jnh2opolo5]

@jnh2opolo5 various other neurotransmitters within an individuals brain. but since it has now been a good deal of time since i originally watched the video I will add in that the typical length of the trails i saw when using LSD or Psilocybin were about 2 feet in length. Mind you that they become transparent exponentially, to the point where they are below detectable levels.

Hope I was of help!

[Slynn42]

My eyes hurt after watching that. Ow.

7

[the215farmer]

Agreed that I've probably seen all of the visuals shown here and more depending on the chemist and amount taken and most importantly The enviroment while tripping.

The enviroment will make or break the experience, emotionally, spirtually, physically and visually. Colors are most vivid, flouresent and bright.

[305spartans]

I would say it differs based on how high you are, and at what part of the trip you're at, but they all look very similar to me. I don't think it matters much really though, the point is that people understand what tracers look like. The speed and distance between frames shouldn't matter.

[hiimmisterdude]

while it can look like this a better way to describe it is more of a fade out trail rather than a strobe trail

[billyeason73]

@hiimmisterdude I agree with this. 9 got semi close,but still too much strobe effect. Fade out trail or blur trail would be a good description.

[andonjuin]

10

although, the trails are usually not replicated images of the hand (like in this example) but more like transparent duplicate images of the hand. if the trails in this video were a lot more transparent, my experiences would closely resemble number 10.

the trails to me usually look like sparkly or glittery transparent waves coming off my hand. they usually stay around for as long as i keep my eyes still. hope this helps

[Neeokalias]

acids awesine. =) visuals like that. its like unreal hahaha a dream i love

[razorsedge1015]

8 more sensual trails of hands, energy is visible...

real beauty is the pattern on our jeans or in our body hair after a bath drains on you, an alphabet soup of patterns, so beautifully created and related, yet each individually unseen, adjust to the energy field, and wala, it is there

[thecultof420]

Id say number 7 but I don't get much trailing. I get alot more fractalization

[luckydjuju]

@farley92569 : I wrote a matlab program to do this, detecting motion at each frame.

[farley92569]

@luckydjuju ahh ok

[farley92569]

btw what program did u use to do this cuz i been wondering for years

[farley92569]

damn its a toss up between 4-7 and 10

[4everpink87]

the 8-10 ones seem to be the closest to what i've experienced.

[sethmuthafuckinlee]

i would say tracers for me are between 8 and 9, but then it also matters as to how much cid you take to begin with. For me its usually between 1 and 3 hits. The most I've ever done was 5 or 6

[CursedExistence]

I experience this visual disturbance without having ever taken LSD. I suffer from a group of symptoms known as visual snow... I see static, palinopsia after-images, trails, halos, starbursts etc. its not pleasant. at all.

[scandmx5atl]

@CursedExistence i agree. i hate it

[luckydjuju]

@marco00ve : it is informative to know that none of these movies corresponded to your experience. Would you mind commenting further, on the linked survey, and letting me know what to do to match your experience better?

@ all of you who visit this page : if none of these movies resembles in any way your experience, please do fill out the survey anyway, and let me know how to make the simulations better. It won't take you much time, but will be extremely useful to me.

Thank you!

[420ARYAN420]

@luckydjuju make the simulations better by experiencing it yourself?

[CorpseResurrector]

@luckydjuju I do not take LSD or any hallucinogen/illegal drug. But I want to say that your video lacks a non-trailing source video for comparison.

[marco00ve]

no one
