For the past week or so I have had a slight sinus infection, with drainage and coughing. I have thought back and it started when I was vaping mostly my DIY juices. I had been using alot of vendor juices for the weeks prior which are more 50/50 pg/vg. In my DIY the only PG in them comes from the flavors. Could the high VG content of mine cause this or am I just overthinking it?
