gonna start this thread as it fits better into the neuroscience forum. here are all infos i could find to this plant.

A psychoactive dose is 28 g lettuce leaves (MILLER 1988: 1170; as the medicinal, largest single dose of the lactucarium
0.3g; the total daily dose is 1.0 g (ROTH et al. 1994: 4440.
ingredients
The Lactucarium contains the sedatively effective sesquiterpene lactone bitter substances (guaianolides) lactucin (C,5H„05) and its p-
Hydroxyphenylacetic acid ester, lactupicrin (= lactucopicrin)'ys, as well as triterpene alcohols (lactucerol), a melampol
Glycoside (lactuside A) and other guaianolides (11ß,13-dihydrolactucin, 8deoxylactucin,
jacquineline, zaluzanine derivatives;
STOJAKOWSKA et al. 1993 and 1994). In the older literature, the presence of a "hyoscyamine-like
alkaloids” (cf. tropane alkaloids) (FROHNE and PFÄNDER 1983: 67£*).
Incidentally, opium-like alkaloids also occur in garden lettuce or lettuce (Lactuca sativa L.) (BIBRA 1855: 259*). if
When the lettuce shoots out and forms stalks, a white milky juice is produced that contains alkaloids that have a sedative effect (RÄTSCH
1995a* and 1995c* ). The variety Lactuca sativa var. capitata L. grown as a garden lettuce is also called lettiice opium or frerich
lactucarilitrl (BROWN and MALONE 1978: 23*).
Effect
Lactucarium has analgesic, sedative and antitussive effects (STOJAKOWSKA et al. 1993). The effect
was formerly even compared to that of deadly nightshade (Atropa belladonna) (HARLAN 1986: 10). You also have them to explain
used for the kava effect (see Piper methysticum).
The effect is described as a "weak dream state" (MILLER 1988:
118*) or aphrodisiac »high«.
The pioneer Freiherr Ernst von Bibra (18061878), who experimented a lot with Lactucarium, came to the following conclusion:
»Very similar to opium, the lactucarium appears to consist of the various species and varieties of the lactuca species
possessing somewhat different properties, but in the main effects it is the same, like opium."
(BIBRA 1855: 255* )
The guaiane-type sesquiterpene lactones found in latex, which are often present as glycosides, are said to be responsible for the sedative
effect (STOJAKOWSKA et al. 1994: 93).
A comparison of the results obtained for two thermal assays
suggests that ibuprofen is a better analgetic than (1), (2) and
(3) in the hot plate test but not the tail-flick test.
Conclusion
On the basis of these investigations, it may be concluded
that lactucin (1) and its derivatives (2) and (3) possess analgesic
activities in thermal models of nociception similar to that
observed for ibuprofen used as a standard drug. The two former
compounds also possess sedative properties. It is noteworthy
that (3), in contrast to (1) and (2), do not affect the spontaneous
locomotor activity of mice and this is a beneficial feature of compounds
with an analgesic profile. These observation confirm at
least partly the ancient use of Lactuca virosa as an analgesic and
sedative herbal remedy, and suggest that not only Lactuca virosa
but also Cichorium intybus may possess analgesic and sedative
properties due to the presence of lactucin and lactucin-like
guaianolides. The mechanisms involved in their action are not
completely understood and further studies seem to be necessary.
I also read that the best way is to use it via the fresh, recently collected, virosa latex.Tried 1,1g of 100:1x extract today, almost no effects. You might get better results with the fresh plant.
