Yes - orange juice can't serve as anything more than a placebo once the LSD is ingested and metabolized (which only takes circa 30 minutes). LSD acts all at once to mess with serotonin receptors in the nervous system, so the bulk of the trip (typically 6 to 8 hours or so) is experienced after the LSD has come and gone.
LSD is metabolized in the liver and the residues are excreted renally (i.e., via urine). I suppose if you drank a *lot* of OJ, you might hasten the flushing of the residues from your body. Even then, I don't believe this would do much to ameliorate the tripping experience.
Anything that calms the tripper (placebos, distractions, having a cup of tea in silence) 'works' to help him / her ride out the trip.
I've personally witnessed two cases in which people experienced with LSD and in the midst of tripping claimed the trip's effects had stopped dead - both involving stress and adrenalin:
(1) One of two people tripping (same acid; same schedule) disturbed a wasp nest and got a handful of stings. He claimed he'd become stone cold "sober" after the stinging, whereas his trip-mate remained a virtual vegetable for several hours. The behaviors of the stingee and his companion were entirely consistent with the storyline. This was at a party event I attended, and I can attest that the stingee was noticeably wasted up until he got stung.
(2) Only a block from one of the hotline / intervention centers where I volunteered, I (and about 15 - 20 others) witnessed a car hit a boy on a bicycle and send the kid hurtling to a hard impact on a traffic island. Everybody froze, except for 2 hippie guys who immediately rushed to the boy, calmed him, carefully repositioned him, administered first aid for bleeding and pretty obvious fractures, yelled someone out of their shock to call for an ambulance, surveyed his injuries, and gave a detailed account of his injuries and status to the police and medics when they arrived only a few minutes later. Everyone else just stood there.
The police officer and medics all congratulated these (otherwise reviled-on-sight-in-that-particular-time-and-place) hippies ("Great work, guys!" "Thanks!"), the ambulance raced off, and the crowd dissipated. The two hippie types were still standing on the traffic island, splotched with the kid's blood, looking lost and bewildered. I walked over to them and asked if they were OK. They said they were 'peaking' on some very heavy acid, and needed help getting out of such a public position. A third person (their non-participating companion) was obviously tripped-out to the extreme. I asked them how they'd reacted so efficiently and effectively to the injured kid, and they both said the shock of seeing him get hit had rendered them stone cold straight during their emergency response. They both claimed they didn't feel trippy again until it was over and they were left standing there, covered in blood in the middle of a busy intersection at rush hour.
So far as I know, orange juice was not involved in either incident.
