Kia ora, In this unit we've started on our next topic science fair. I have been given an opportunity to choose with my partner, Ocean to investigate if non-nicotine vaping is less harmful than nicotine vaping?. We will be looking into different vapes, health problems etc. Our hypothesis prediction is if non-nicotine and nicotine vaping actually leads to popcorn lungs. Which one are you choosing that is less harmful?
