Can we start doing this with everything?

The problem is a lot of nasty things come from less scary sounding things. For example:

Ingredient: Ricin, Where it comes from: Castor beans, What it’s used for: Poison.

There’s actual truth to this. In toothpaste no less.

Ingredient: Asbestos

Comes from: naturally occurring mineral

Used for: mild abrasive

To be fair here though, how much toothpaste do you dry and snort these days?
