Hi, you are you doing?

I was a light smoker (1-3 cigs a day) and about a month ago I switched to vaping.

I chose to vape flavorless 70/30 juice with 1mg/ml nic.

I've been using the Vaporesso Cascade One Plus, which is a stick type kit with the Cascade Baby tank. The 0.18 ohm gt mesh coil is the one I chose.

After about a week, I've noticed irritation, dry mouth, and a bit of a sore throat after using it for a while (mostly after chain vaping).

After some research, I've found 1,3-propanediol (PDO) could be a safer alternative to mitigate undesired side effects of 1,2-propanediol (PG) sensitivity, which matched some of the above observations.

I got my hands on some ZEMEA USP grade PDO here in Brazil, some bi-distilled VG and freebase 100VG 100mg/ml nic.

I then produced 70VG/30PDO 1mg flavorless juice, and these are my subjective impressions:

• The undesired irritation is pretty much gone

• Viscosity is about the same. Cloud production as well.

• Pure 70VG/30PDO 1mg has a bit of a salty taste when compared to 70VG/30PG 1mg, which is sweetish

• The nicotine throat hit is pretty close, I'd even say it's a little bit stronger on 70VG/30PDO, but I could be wrong

Tl;dr

Overall, a much more enjoyable vaping experience for me out of PDO than PG
