I would like to share with you my experience with the novel research chemical 1P-ETH-LAD which has recently appeared on the market in the UK. Being a fan of the mind states induced by LSD-25, I decided to run an experimental trial with this substance due to the short time period in which it will remain legal before the...

Summary
1P-ETH-LAD is a propionyl prodrug of ETH-LAD that rapidly de-acylates in human serum to yield the active compound ETH-LAD. It is reported to be moderately to significantly more potent than LSD by weight. Start with low doses (50 ug or less) if inexperienced.

Effects
Aggregated from 3 single-substance Erowid experience reports
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 3 single-substance Erowid 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?

100ug 1P-ETH-LAD trip. T:00:00 It was 11:00, 31/01/2016. The flat was a little cold, but otherwise the setting was good. My fiancΓ©e was in the bedroom, not feeling well, so this was in essence a solo trip.
I'm a bit at the cutting edge of psychedelic research, confidently exposing myself to completely novel Lysergamide RC's supplied by the most trusted RC vendor known to man. Some might find this pass-time dangerous, I find it fascinating.

Add missing routes to PsychonautWiki Journal
The PsychonautWiki Journal app already has 1P-ETH-LAD, but its built-in entry only covers Oral. Here are the other routes we have data for. You can't edit a built-in substance, but you can add a Custom Unit for any of these routes to log it.
