Hi Emma,

I'm pretty sure a bit of second hand smoke will not hurt your baby. If you were around a heavy smoker every day and breathing it in, or if you felt the effects of the joint yourself, well then I wouldn't be happy either.

Quite frankly I reckon it's kind of the same as being in the smoggy city for a bit, or trying to light the stove and being able to smell the gas. For a one-off I don't think you need to be worried.
