Though evidence shows that LSD interacts acutely with diverse regions of the CNS, and while the drug clearly appears in high concentration along visual pathways, no evidence has been presented that clarifies whether the drug operates at any CNS site on a long-term basis. Of
special note is the association between LSD-type flashbacks and the use of marijuana. Six separate reports linked flashbacks to marijuana use, but in each report the subjects described an antecedent use of LSD that also explained the flashback.
Further data from the survey of 720 servicemen in western Europe failed to find a single case of flashbacks in any subjects for whom hashish was the sole drug of consumption.
In the same sample, however, 15 subjects were found for whom LSD flashbacks were precipitated by marijuana use.

this one refers to Diane to Linkletters death.
Diane Linkletter was the 20-year-old daughter of Art Linkletter, the prominent radio and TV personality. Before an autopsy had even been performed, her famous father claimed to the media that she had taken LSD the night before her death. (Linkletter had not talked to his daughter before her death, but maintains that she had told her brother Robert that she had taken the acid.) He was quoted as saying, "It isn't suicide because she wasn't herself. She was murdered. She was murdered by the people who manufacture and sell LSD."
When the autopsy showed no signs of drugs in her system, he changed his story to claim that she was suffering an LSD flashback from months earlier and that had caused her to jump out the window.
The media, of course, ran with the story, and used Art Linkletter's claims to create the narrative, without doing much investigating of their own. By the time the dust had settled, the story had been transformed in most people's minds to reflect an old urban legend about a girl, high on LSD, who jumped out her window because she thought she could fly.
A much more accurate picture of what happened can be gleaned by examining the testimony of Diane's boyfriend, Edward Durston, who was present when she died. Diane had summoned him to her apartment at 3 am and had spent the final six hours of her life with him. He told investigators that she was a desperately unhappy and despondent young woman who was determined to end her life. He had no reason to believe, and she had not indicated, that drugs were a factor in her death.
Art Linkletter, understandably devastated, became one of the most vocal critics of the counterculture, speaking out against drugs at every opportunity, while telling the tale of his daughter's LSD death. Dr. Timothy Leary, the LSD guru who had urged young people to "turn on, tune in, drop out," became his archenemy.

Do you know how psychological studies are conducted? Do you understand how sources like I listed have a vested interest in maligning ANYTHING to do with "illicit drugs?"
Studies 2 and 3 you showed I automatically threw out as biased, with a goal to make the reasearch "fit" ( Much like Art Linkletter was determined to blame LSD for his daughters death)
The first study is is the only legitimate study -control groups, interviews with psychiatriasts, referall etc. I won't go thru the methodology, unless you've had psychology (my major in college) it would be a waste to try to explain how statistical data can be manipulated.
I will say the first link looks legitimate, but defines a "flashback" as even seeing a 'spontaneous geometric pattern " - did that ever happen to you?
( assuming you never dropped acid?).
I would look thru it further, it does look well established, the problem is it links flashbacks to marijuana use, so I'm left wondering if this is biased also.
Throw out 2and 3. Why don't you tell me why study #1 is valid? , and I'll respond. Let's see if you have any idea of what you link here. or just fishing?
Just because you google it up, doesn't mean there is any science behind it.
