^^^ Not true about the Vitamin C terminating a trip.
Found this (Source: Bob Greer, MAPS):
"A study in the 1970's examined a large group of chemicals for an immunizing agent to protect people against the effects of LSD.
The study checked over 200 compounds and found only two with significant prophylactic effects (i.e., that created a tolerance to LSD).
The most effective one was LSD itself. Nothing developed a tolerance to LSD better than the drug itself.
The other was Vitamin C, which ameliorated the confusion associated, often, with LSD. The researches commented strongly on the alteration of the effect: people who pre-treated with Vitamin C "tripped" but were less inclined to "get lost" in the experience and apparently maintained a less conspicuous social poise. (The potency of the LSD was also somewhat reduced, but this did not account for the _qualitative_ difference in the experience for these people, according the researchers.)
The study didn't relate the dosages or interval between Vitamin C and LSD administration. However, the "street knowledge" about this is:
1. The Vitamin C can prevent (sort of) the LSD experience if they are consumed together, especially if the Vitamin C dose is large (1 gram or more). A sort of mild up-and-down experience can result from this combination
2. Taking the Vitamin C two hours before LSD works well.
3. Taking enough Vitamin C to saturate the tissues works well if enough time is allowed (2 hrs., perhaps less).
4. The LSD effect is slightly weaker, quantitatively speaking, than without Vitamin C, and ends sooner too.
5. It's typically easier to sleep afterwards also.
6. The "sense" of time, and of distances, is less disturbed with also.
3 grams of Vitamin C will saturate most people's bodies well. A good method of eating this much C without gastric discomfort is to drink a solution of 3 grams of buffered Vitamin C that is dissolved (not just stirred into!) in a glass of water. (People who keep their bodies saturated with Vitamin C may notice that their urine is colored a brilliant yellow color. This is normal.)
It's possible that a smaller dose of Vitamin C will have the same effect on LSD effects; a half-gram tablet might be sufficient for example. However, a significant time delay will still be required before taking LSD.
I suspect that the "confusion" that Vitamin C reduces is actually very valuable for death-rebirth religious experiences; it's not a "bad side-effect" of LSD, in other words. However, such confusion makes an LSD user very vulnerable to "head-trips" and other dangers (that may occur either inside or outside of a "controlled setting"). There seems to be less of the amphetamine-like edginess of LSD in this combination; and I suspect the difference is not just the result of acidic urine washing the body clear of an exogenous amine.
The Vitamin-C ameliorated LSD experience sounds a lot like that ascribed to LSD analogues (such as the di-allylamide) although the potency is only slightly less than plain-vanilla LSD. For example, visiting a badly maintained, nudie-strip bar favored by US Marines on the 4th of July in a border town near Camp Pendelton would (for an experienced LSD user) be
practical on the Vitamin C-LSD combination; the same situation might be unendurable otherwise. Likewise, law-enforcement personnel will notice a difference in poise, but they will not necessarily feel threatened by it.
Incidentally, ingesting LSD dissolved into (chlorine-free) water will smooth the introductory phase of the experience (regardless of Vitamin-C pre-treatment); LSD taken on paper tends, otherwise, to start very abruptly."
*NB This is NOT a recommendation to start necking large quantities of vitamins* (SWIJ's addition!)
Also found this:
"Ascorbic acid. Hoffer(1959) pretreated a few subjects with 4 grams of ascorbic acid each day for several days, then gave them LSD. Other subjects were given ascorbic acid at the height of the experience. This vitamin did not change the intensity of the experience but it did alter its quality. there was no decrease in the intensity of perceptual changes. the subjects were able to concentrate better and developed less paranoia. twenty-four hours later subjects who had been give ascorbic acid were not as tired as the controls"
