@Luke5533 as I understand:
PG = propylene glycol (pharmaceutical grade) provides throat hit and also acts as a flavor carrier
VG = vegetable glycerin (pharmaceutical grade) provides the clouds
** PG much thinner than VG
Most e-juice are made with a 50:50 ratio PG/VG although some are available in different ratios. A lot of people dilute commercial e-juice with VG (available from pharmacies and convenience stores like Spar / Pick 'n Pay etc) for a lower nicotine content and/or to mute overpowering flavor, and will also provide a milder throat hit with increased clouds.
Hope it makes sense.
