    Summary dose.wiki TripSit PsychonautWiki

    1-Acetyl-N,N-diethyllysergamide (also known as ALD-52, 1-Acetyl-LSD, 1A-LSD, 1A-LAD, and mistakenly as Orange Sunshine) is a lesser-known psychedelic substance of the lysergamide class that produces LSD-like psychedelic effects when administered. It's structurally related to psychedelic lysergamides like LSD and 1P-LSD and is reported to produce largely indistinguishable effects. ALD-52 was originally discovered by Albert Hofmann in his study of LSD analogs, but it did not enter mainstream awareness until the 1960s through Western youth counterculture.

    Perspectives

    “As expected this is somewhat similar to LSD with respect to the headspace. It diverges in terms of having a heavier bodyload, less visuals, and a sort of darker more neutral headspace, lacking the giddiness that LSD can sometimes impart.”

    Effects Erowid Bluelight

    Aggregated from 13 single-substance Erowid and 5 Bluelight experience reports; 18 Erowid reports where another drug was taken too are left out

    Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect or something witnessed can count). Mentions saying the effect did not happen are left out; that check reads keywords, so it can miss some. The shaded band on a bar, and the small range after its number, is the 95% interval: where the share could plausibly be with other reports of the same kind. Fewer reports, wider band. Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.

    Too few reports for bars: these effects come from 13 single-substance Erowid and 5 Bluelight reports, and a bar is drawn only from 20 reports or more. With fewer, a percentage cannot tell a common effect from a rare one. Counts are shown instead. Why 20?

    Also reported in combinations. In the 18 ALD-52 reports where another drug was taken too, 4 mention hospital, emergency services or an overdose, 0 a seizure and 1 psychosis (too few reports for percentages). In the 13 single-substance reports: 4, 0 and 1. These are not in the figures above: they cannot be put down to ALD-52 alone, and a mention is not always something that happened to the writer.
