Is This Marijuana?

I thought it looked enough like marijuana that I stopped to take a picture of it. I was going to pinch off a leaf to take back to the botany lab, but there were a couple of cops standing about five feet away and I was afraid it was all an elaborate drug sting. Anyway, it’s growing out of a crack in the sidewalk on civic plaza, over on the north end by the crosswalk.
