How dosed are John and George in some of those pics?
A little background is apropos:
John and George were the first Beatles to try it, although their first experience was actually non-consensual (!)
Both experienced LSD for the first time together at a dentist's house in early '65.
From the
Beatles Bible:
"The precise date of the first encounter is unknown, although it's likely to have been in March or April 1965. It is known, however, that it took place at Flat 1, 2 Strathearn Place, London W2, in the home of 34-year-old cosmetic dentist John Riley."
John recounted later:
"He laid it on George, me and our wives without telling us at a dinner party at his house. He was a friend of George's, and our dentist at the time. He just put it in our coffee or something. He didn't know what it was, it was just, 'It's all the thing,' with the middle-class London swingers. They had all heard about it and didn't know it was different from pot or pills. And they gave it to us, and he was saying, 'I advise you not to leave,' and we thought he was trying to keep us for an orgy in his house and we didn't want to know.

By their August '65 tour they were familiar enough with it to have arranged to pick some up from a source in New York and take it to LA for the party with McGuinn and friends where the Peter Fonda episode occurred that inspired John to write "She Said She Said", also recounted in that Beatles Bible forum ("the Beatles and Drugs").
Ringo's first time was at that party and Paul was still the holdout for another few months.
Anyway, that was just to set the scene for the fact that John was unquestionably the most frequent flyer of the bunch, George started tapering off before John.
Also, heavy users actually develop tolerance for LSD< the effects aren't as strong if one doses several times a month, even with increasing dose.
I suspect it's related to neurotransmitter metabolic chemistry as in how long they take to refresh after their normal cycle's accelerated or disrupted.
Very little was known about that stuff at the time but LSD was one of the agents stimulating early research into the role of serotonin.
Low serotonin's associated with depression, now.
Anyway, the point's that both of 'em could probably "maintain" at small dose levels (Guessing 100-200 mics for John by '67 was probably about as strong as smoking a joint if that even, depending on how long it had been since the last trip, suspect a little lower for George but don't know.
Suspect John routinely handled dosages in the 1000 mic range during his high tolerance period, which would cause total reality disconnect for most folks.)
So suspect John could "maintain" more easily than George just based on his known heavy usage and therefore higher tolerance.
Physiological signs still occur though, like dilated pupils, and psychological effects still accrue and compound over time, as was evident in John's gradual withdrawal and introversion, to the point where his friends became concerned.
John's description of their first trip's in line with probably a couple hundred mics, where hallucinations are pretty strong but one still has a sense of having a body and being in the "real" world but seeing new dimensions in it and a feeling like the "stuff"'s been there all along but one just couldn't see it..
Anyway, with that frame of reference, suspect for sure pics 1 and 5; from the
Magical Mystery Tour movie filmed in mid '67.
They've just got that "look" especially John's childish bemusement in pic one and the general awestruck look on both of 'em in pic 5.
Pic 4 from the Sgt. Pepper's launch party May '67: George's eyes dilated, John just looking like he's "coming on", when users typically describe the initial euphoria of onset.
Pic 6? Not so sure but George's dark shades might be a clue, credited as:"John Lennon, Estelle Bennett, George Harrison, and Nedra Talley during the final Beatles US tour (1966)".
Pics 2 & 3 don't think they're actually "dosed" at all, they just appear a little too "alert" and involved with the moment. Or else a pretty low dose (Original manufacturer Sandoz Laboratories packaged the stuff in 25mic ampoules for psychiatrists, and they would have considered 100 mics a heavy [and probably non-recommended] dose).
These well-known photos from "the White Album"?:
Dilated eyes say it all, the only one I'm not sure about is Ringo but he's got the light right in his eyes.
