This was my third experience with 4-AcO-DALT, and my first time taking it orally, after smoking it the last two times. I knew that it was supposed to be much less potent this way, and unfortunately that turned out to be true, but I still thought it would be worth it for the sake of having a fuller experience by getting...

Effects
Aggregated from 5 single-substance Erowid experience reports; 3 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 5 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?

About a week and a half ago I wrote a rave review of smoking 15 mg of 4-AcO-DALT, but I deleted it a few days later because it was too informal and I didn't want my first impression to paint the wrong picture of this substance. This time, I decided to write a more professional trip report and give my thoughts.
Setting: House Party Regular Meds: Currently none Drugs taken in past 24hours: I had done some ethylphenidate, etizolam and mebroqualone the night before and had drunk around 1/4 of a bottle of rum before taking the 4-AcO-DALT Previous psychedelics experience: Phens: 2C-B, 2C-B-FLY, 2C-C, 2C-D, 2C-E, 2C-I, 2C-P, 2C-T-7...
At the time of the Experience, I'm taking almost daily; 200mg magnesium citrate, 1000mg Cod liver oil, B-complex (100% RDA rec)+ 0.25 mg Melatonin at night to Help with sleep. 16.15- took 60 mg 1 hr after a light meal, also took one sickness pill with the meal in case of nausea.
Experience - more substances than I care to mention but not many tryptamines, only 5-MeO-DALT and whatever's in mushrooms before this. I am not on any meds. Set and setting - I'm home, I'm happy, I've had a couple of beers. Let's give this a try...
Used mixture: 35mg of 4-AcO-DALT and a hint of citric acid, dissolved in saline solution. Set & Setting: Alone in a studio with some low lights and soft trance music. Interested in the substance, emotionally a bit shaken, but well, physically healthy.
