Propylene glycol (PG) is a common base used in e-liquids due to its ability to carry flavors well and provide a strong throat hit. E-liquids with a high PG content are often referred to as "PG-heavy" liquids. These liquids are thinner in consistency compared to those with higher vegetable glycerin (VG) content, making them more suitable for use in devices with smaller coils and wicks, such as pod systems or mouth-to-lung tanks. Additionally, PG-heavy liquids may be preferred by vapers who are sensitive to VG or who enjoy a stronger throat hit. **
