I'm sure more experienced members will weigh in but in order for anyone to help you properly, you'd need to be a bit more specific.
- have you been smoking and are you trying to switch to
vaping?
- for how long, how many cigs a day, what type of cigs?
- what do you think you crave more in the process - throat hit, clouds of smoke/vapor,
tobacco taste, nicotine intake, hand/mouth experience?
Without answering those it's like asking what car you should buy, or what PC. Probably even worse because there's more variations to
vaping than there is to cars or even PCs. Don't be afraid of variety though, it's just a matter of choosing a good starting point.
