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.

If you weigh 100kg, drinking 90*100g=9kg of water produces a 50% chance of fatality. The definition of LD50 requires the dose to be given "all at once", and quite frankly, you would not be able to drink 9 liters of water all at once. LD50 becomes a lot less meaningful for anything where you would need an extreme concentration of the substance--e.g. THC is difficult to acquire in concentrations compatible with fatal overdose--or where consuming it at such quantities is simply infeasible.

People often say "consumed rapidly" but that phrasing doesn't really solve this problem with LD50 as a measure. Basically LD50 is meaningful near the bottom of this chart, less so near the top of this chart.

I'll note that another problem with LD50 is that it doesn't take into account serious harms that can occur with lower dosages. Drinking any amount of gasoline is likely to lead to serious brain damage, for example.

Everyone knows the LD50 is a binary condition! Either you live or you die! That's why I always dose just under the LD50 to make sure I never suffer any consequences.

This is true about everything in life, it's called living on the edge 👌
