I'd like to observe, that although funny and drawing a lot of attention, this thread is wrong.
Spiders ARE poisonous. Plenty, if nost the most of them, really. By default we simply do not consider them food, but they are eaten in some parts of our world, nevertheless.
And yes, spiders, ar least some of them are venomous.
Omg that's really interesting, I never would have guessed! Are the effects of the venom and the poison similar at all? I kinda had the intuition that venoms were generally at least kind of edible, probably just because snake venom is lol. Is it even the same chemicals between the two effects? Sorry, my mind is just blown, haha
There are many toxins and some might produce similar effects when ingested, to those that were injected into the bloodstream. Some among these are similar to alcohol poisoning, some might probably give you a drug-like bad trip, others might be fatal. What I'm trying to say is, that there are many variables involved and the result "might vary".
