What is the best way to quit smoking?

Well the best method to quit smoking would be to use a vaporizer or better known a vaper (electric cigarette), the best equipment to start using would be, a starter kits which are those starter kits more than anything recommended (this is from my point of view view) of the brand smok.

Pen 22: It is the first single-body multipurpose set from SMOKTech, combining beautiful and ergonomic design elements with an internal 1650 mAh battery and a direct output voltage system.

These equipment, apart from being economical, brings you 2 resistors, a usb cable to obviously charge your device and normally in authorized stores to sell these equipment for those over 18 years of age, they always give you a pot of e-liquids with 3 mg or 6 mg or the maximum of nicotine would be 12 mg of nicotine or it could be with 0 mg of nicotine that this would be an e-liquid without any nicotine. All depending on the client.
As I had already mentioned, these are the best starter kits from my point of view since I have used all those equipment and they are good and cheap.
