I am thinking of giving up smoking potentially.
How do the E-cigs compare to a real cigarette?
There's three key benefits to them:
1). Nicotine. This is a given. However, a good thing about e-cigs is that you can choose the nicotine dosage. For example, you can start at 12-18mg (depending on how strong your habit was) and then gradually taper down to 10mg, 8mg, 6mg and even 2mg.
2). Throat hit. I think one thing which people miss is the throat hit, but this is easily achievable with a high PG e-juice and a strong flavour like mint or menthol. I know some folk who can happily smoke cigarettes but cough their lungs out with an e-cig because the throat hit can be so strong. However, it is adjustable.
3). The action. Many people just miss the action of smoking a cigarette, but an e-cig solves that problem nicely. Instead of picking up a cigarette, just pick up your e-cig to satisfy those "hand to mouth" cravings.
All in all, it caters to the three main factors which people usually miss the most when they try to stop smoking. Obviously, if someone simply loves smoking cigarettes, then it's not going to be the same, but if you want to give up, they can be extremely helpful.
It is of course better to just stop completely, but for many people, that's easier said than done. Using an e-cig and then gradually tapering down is definitely much healthier than continuing with normal cigarettes though. If they do eventually help you to give up entirely, then they've done their job.
