Sure it can. So can Vitamin C though.

The overall point remains the same: the toxicity, both short and long term, of MMA, is comparable to lots of everyday substances that are both commonly eaten and inhaled.

It just isn't that toxic as far as chemicals go. That doesn't mean it would be like great for you but calling it "highly toxic" is tremendously overblown and doesnt serve anyone well to claim.

Let's save the highly toxic claim for things that actually deserve it. We don't have to sensationalize everything. I maintain my view that the explosion would likely be much much worse than the odds of significant respiratory damage from MMA.

Also note the sensationalization also causes placebo effect. People miles away started claiming "their lungs hurt" when

1. There was no leak

2. Even if their was and it was a conspiracy or whatever, your lungs have ~no pain receptors and your chest/pleura/etc would generally not hurt from MMA overexposure. Your throat would and your skin would, depending on concentration. But nobody complained about skin irritation when the is basically no way to end up with one without the other.

Etc.

Sensationalization of this hurt people so far more than the actual issue!
