If you are in the US I would guess it's some kind of locust, possibly black locust. Assuming it's not an ornamental, a good tree ID book covering your area would be your best bet.

To my knowledge locusts have not been assayed in any way for DMT.

Hmm... If this is black locust, then maybe I have found an Acacia? To my knowledge, there are only two locust trees that grow in my area: Black locust and honey locust. I haven't seen this particular one, but I have found a locust that looked different from this.

The reason I bring this up is because if I'm right and there's only two locust trees in my area, then I have found one Acacia and a bunch of honey locust. I wish I knew where my pics were so that I could post some. I'll look today to see if I can find them.

well what i have searched on the web this really looks like black locust. this tree was set in front of the building like a decorative tree so it's not about the region.

Ah, it turns out my "Acacia" is actually honey locust. The pics on this page gave it away.

On closer inspection of your tree I see no thorns on the trunk. The trees that I found have short, single-pronged thorns on the trunk and branches.

Black locust allegedly never rots. It is a popular wood for Native American bows. Just sayin...

its really impossible to tell without looking at more features of the plant. photos of the leaves especially would be good
