Poison is generic. Venom is specific to normal method of delivery (e.g. snakes and bees).
Swallowing venom may or may not hurt you. Probably not a great idea, but there’s a better chance you’ll be okay.
Getting a known poison stabbed/injected intravenously seems likely to be pretty effective, but it depends on the mode of action. Blood goes everywhere in the body, so it will likely find its target eventually.
Unpopular opinion (at least in the Fediverse): while mastodon exists and is nice (if a little harder to grasp), Threads actually has a sufficient user base to be considered a substitute for Xitter. I was watching it during the debates and there was lively enough conversation to be interesting and still unable to read every comment that tagged the debate in real time.
Down with centralized social media and all that, but just a suggestion if you miss the volume of posts and the centralized interface that Xitter dumps out.
