In my research of OTC highs, the two main ones that stuck out were dextromethorphan and dimenhydrinate. I have used DXM five times now and I have found the trips quite insightful.

Summary
Scopolamine is an extremely potent anticholinergic deliriant; doses above the therapeutic range can cause true hallucinations, complete memory fragmentation, dangerous confusion, hyperthermia, and severe dehydration. Accurate measurement is critical—milligram scales are required. Recreational use is strongly discouraged in unsupervised settings.
Dose Information
| ROA | Threshold |
|---|---|
| Oral | 0.1-0.2mg |
| Transdermal | 0.3mg |

Effects
Aggregated from 12 single-substance Erowid experience reports; 5 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 12 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?

Also reported in combinations. In the 5 Scopolamine reports where another drug was taken too, 1 mentions hospital, emergency services or an overdose, 0 a seizure and 0 psychosis (too few reports for percentages). In the 12 single-substance reports: 3, 0 and 0. These are not in the figures above: they cannot be put down to Scopolamine alone, and a mention is not always something that happened to the writer.

It was the summer of going from grade nine to high school. By this time I had been smoking weed steadily for two years, tried various types of opiates and hallucinogenic, and Id even formed a border line addiction with both prescription amphetamines and benzodiazepines.
This is a story of me have a trip (if u can call it that) off of scopolamine, even though I didnt relize it till months later.( I think I may be hypersenstive to it or something) -------------------------------------------- 2 summers ago I went to my uncles house in virgina to go fishing.
When I was eight years old, I was prescribed a scapolamine patch by a physician's assistant for nausea. They applied the patch to my neck, and after only a few hours (3-4 at the very most) my sister had realized something wasn't right and removed the patch, promptly thereafter washing the area on which the patch had be...
This experience was so radical I still remember it vividly after 30 years. My friends came up on a pallet load of expired drugs from a hospital headed for the hazmat dump site. We went thru the hard stuff MS, Diluadid, Dexoxyn, etc.
Subject orally ingested 7mg of racemically-pure scopolamine HBr in aqueous vehicle. No other psychoactive substances were combined with the scopolamine. The quantity of scopolamine is decided upon because it is 1/50 of a lethal murine dose; subject figures that this is a sufficient safety factor.
Firstly I would like to say Im 21. When I was 15 I hate a whole medium sized datura stramonium plant with about 15 leaves and 4 apples on it. I had an amazing 3 day hallucinogenic festival all to myself (in hospital, Basically, if you take enough datura to have a hallucinogenic experience, youll end up in hospital or...
This happened quite a while ago when i was in a hospital, i had been admitted because of error, but got to try scopolamine. BTW I had not eaten food for 6 hours, my stomache felt empty preceeding the intake of scopolamine.

I was recently dosed unwittingly and I have been trying to figure out what I was given. I have no experience with Date Rape drugs but it fit all of the symptoms I have read. How could this have been given to me while fast asleep, needles? Is there a spray or something? I did not have any alcohol in my system.
0.3mg tablets weight: 145 lbs age: 18 not all these times are correct as i was so fucked up to know the real time or fake. T+0:00 - drinking T+1:00 - finished half the bottle and dosed 5 tablets 1.5mg (didnt really expect to hallucinate off this low dose as iv done 6.3mg before and tripped hard) T+1:40 - feel really si...
