Question
I think this is stinging nettle, which grows nearby, but some non-native Lamiaceae in the area also have opposite, toothed leaves with flowers growing along the stem. In a disturbed area in Massachusetts.
Answer
Dear jfc, yes, it appears the plants are a species of stinging-nettle (genus Urtica). I can't tell you which one for certain from the image. The native Urtica gracilis lacks long bristles on the stem (but has short hairs and stinging hairs) and has stinging hairs usually only on the lower surface of the leaf blades. That is who this likely is (but I would need close-up images to be certain).
