Last night my wife lighted some Oud that has a good smell in the house, so I was smelling all that smoke, I felt my head is going full or heavy feeling.

I think smoke in general is affecting me, but cigarettes smoke is more dangerous than others.

Because if I smell cigarettes smoke, I feel so tired next morning!
And like half of that day I continue to feel tired but at the end I think my body is getting recovered!
