I drove by a house that was on fire--it was very old, and the paint was probably lead. Did I inhale lead?

Fortunately when driving by, I had my air conditioning set to MAX A/C, meaning it was circulating air. All the same, some of the smell from the fire still pregnated the cab of my truck. I am worried that I may have inhaled lead, amongst other substances, from the burning house, since it's in an old neighborhood. Could I have had enough lead exposure to literally shear off IQ points, or cause any other problems? I had no acute health effects after the exposure, but I'm still concerned.
