I Smoked with my Cousin

I saw it

And when I got in the passenger seat I forgot to look back because all my life I knew my cousin didn't smoke in her life until today...
So then I just faced forward but then I saw smoke coming out and I was like WTF... So when I asked she said something with a water bottle trick that you can do but I didn't believe that so then I tricked thinking I looked away but I saw it...
