(source)There is no evidence that LSD alters liver function
I thought LSD was excreted renally (kidneys), but metabolised in the liver.
LSD My Problem Child said:The concentration of LSD in the various organs attains maximum values 10 to 15 minutes after injection, then falls off swiftly. The small intestine, in which the concentration attains the maximum within two hours, constitutes an exception. The elimination of LSD is conducted for the most part (up to 80% ) through the instestine via liver and bile. Only 1 to 10 percent of the elimination product exists as unaltered LSD; the remainder is made up of various transformation products
Psychedelics Encyclopedia said:LSD is a very curious chemical. When given by injection, it disappears rapidly from the blood. It can be observed when tagged with Carbon 14 in all the tissues, particularly the liver, spleen, kidneys, and adrenal glands. The concentration found in the brain is lower than in any other organ -- being only about 0.01 percent of the administered dose. [...]
LSD is highly active when administered orally, absorbed through mucous membranes or through the skin, and is almost completely absorbed by the gastrointestinal tract. Concentrations in the organs reach peak values after only ten to fifteen minutes; then they decrease very rapidly. [...] Some 80 percent of injested LSD is excreted via the liver, bile system and intestinal tract, with only about 8 percent appearing in urine.
I'd bet that hepatitic function doesn't play a very large role though; I don't think any of LSD's metabolites are near LSD itself in terms of potency. I still wouldn't be dosing if my liver was in bad shape. though!
