After Portland thugs sprayed protesters with tear gas in July, over 1000 of the protesters reported medical problems that did not quickly go away.

In particular, it seems to have a tendency to cause abnormal menstruation. I wonder if it can cause abortions also. Would Republicans ban tear gas, if so?

We say "tear gas", but I've read that there are different products with different composition. They might have different medical effects, too. I wonder what kind, or kinds, the Portland thugs sprayed.
