Is this something I should be worried about?

So my MIL used to be a heavy cigarette smoker but when I got pregnant she made the effort to quit and hasn’t smoked a cigarette since June. Now she just vapes her nicotine. I recently read that you can get 3rd hand smoke from vaping. Should I be worried about her holding my newborn when he gets here since the vape “aerosol” apparently seeps into her clothing?
