Rules for Posting Guides on Our Community

1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.

2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.

3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.

4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.

5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.

6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

Pretty sure chloroform is wrong too.

Chem teacher had some and one kid stupidly took a whiff. She dropped like a sack of potatoes. She woke up in a few seconds but yeah - that shit was instant.

I guess it might take 5 minutes to get enough to be out for a few hours.

Here's what I can find that gives a better answer. Above 100ppm, you'll rapidly start feeling dizzy. But chloroform is also highly volatile, so you would need to have a rag soaked in chloroform just before attacking someone, rather than lying in wait for a few minutes to a few hours. Plus, if you get that concentration too high, you can accidentally kill someone.

So if you'd been hiding in someone's car for 10 minutes, that rag might have lost enough efficacy that it would take a few minutes. Alternatively, if the person in the backseat doused the rag just before attacking the driver, it might be nearly instant.
