It could be more toxic; it could be less. It could be differently toxic, so that it's no longer as effective against its target but could cause severe harm to other species.

no and yes, no because it wont kill you and yes because it will give an upset stomach

the real question is... CAN IT EXPIRE?

some poisons like cyanide actually do have an expiration date and once it's expired it wont kill you, but it will make you sick

Well . . . no. But some may not be AS bad for you.

And I don't know what kind of person you are, so I'm not going to recommend trying. Actually, you know what? Go ahead, if that's your type of thing.

Wait….IS it good for you?

depends what ingredients you use (bleach)

Holy shit ur right

yo true
i wanna know the answer now

poison don't expire you could use oil not veg oil crude oil

if it did then i woul probobky be less effective
