Would you be upset if you ate something every day and didn't understand the risks fully and then developed a disease because of it? What if no one understood the risks aside from the entity that sold it to you? Would you be upset if someone you cared about deeply, say a child, made a mistake of never understanding there was a risk to consuming something, say, baby food, and then developed a life ending disease because of it? Would you feel responsible if you facilitated giving that person you cared about the food you chose to buy and there by aided in ending their life prematurely?

Any of these scenarios should make it obvious there has to be some sort of regulation around these things, as no one individual is an encyclopedia of toxic substances, and we exist in a bazaar of choices.

There could be a compromise, much like there is with alcohol and tobacco, that if you absolutely wanted to buy something toxic, you could do so. However, that wouldn't really necessitate that you couldn't use it to harm someone else.
