Hi fellow SGean.
Welcome to ECF.
After 5 post u can hop over to
SG Vapers
. E-cig aka PV is to us a Electronic Nicotine Delivery System.
It is typically made up of 3 parts. Battery-Atomiser (heating element)-Cartridges.
The battery provides the power to the atomiser which vaporises the cartridge holding the nicotine liquid into a fine mist which u then inhale.
Edit- Taste wise is up to individual but certainly u will smell better than others due to 'no more stinky smoke' on u~
