Only in it’s liquid or solid form - it can actually be used medicinally in it’s gaseous form.
Honestly, I think a lot of the problem is that science education in this country is so bad that it’s possible to pretty much avoid ever taking a decent science class*. This doesn’t just deprive people of a science education (which is a shame, because a well-taught science class is tremendous fun), but it also deprives them of a class which will teach logical, critical, analytic thinking. I’m certainly a huge supporter of the humanities, but analyzing literature is not grounded in logic the way that science is.
*Only now am I beginning to realize how damn lucky I was that I had plenty of science options to choose from in high school, and how insanely lucky I was to have teachers who were not only true scientists, but also good teachers. (had some awful ones, too, including one whose name I can’t remember, nor can I remember actually learning a single thing in that class.)
