If you're sensitive to PG, look for high VG e-liquids, typically labeled as 70VG/30PG or even max VG, which contain minimal to no PG. High VG e-liquids are smoother on the throat and less likely to cause irritation or allergic reactions in PG-sensitive individuals. Be aware that high VG e-liquids are thicker and require compatible hardware, such as sub-ohm tanks and coils, for optimal performance.
