Is it dangerous to smell cigarette smoke while pregnant?

I don't smell it all the time but today This one guy was smoking in I inhaled it a whole bunch. For some reason cigarette smoke is really strong to me, I was in my car with the windows rolled up and there was a guy far away smoking and I smelt it, and I asked my mom if she could smell smoke and she said no. I guess your senses really do get sensitive when pregnant lol. But anyways, will inhaling some smoke cause any harm to the baby? I'm like a month pregnant so I'm being very cautious.
