Most people seem to use vapers.
The single biggest tip I can give to a new vaper is that vaping is NOT smoking. There are several little things you do when you smoke that you don't think about that don't work very well when you vape.
i) instant nic hit. With an excellent setup you can get an almost instant nicotine hit the same way that you get from smoking, BUT it takes know how and experience to build your own coil, pair it with the right juice and use the right power settings, you can't get that off the shelf (yet) In particular using the usual starter gear like an eGo with a cheap clearomiser or a ProTank Mini, you can't get it at all. When you first start vaping this is the biggest difference you and your body need to get used to.
ii) throat hit. The second biggest difference is throat hit. If you're like me you'll find it extremely funny to hand your vape to a smoking friend for them to have a go on, and then collapse about laughing when they inhale like a cigarette and then cough their lungs up for a couple of minutes. The throat hit is caused by the nicotine in the liquid. In smoke the particles in the smoke are much finer and get drawn into your lungs and absorbed there. In vapour the size of the vapour particles is bigger and they stick to and are absorbed by mucous membranes in your nose and throat. If you take a hard drag on an e-cig directly into your lungs (cos the vapour is cooler than the smoke you're used to) then lots of nic will hit the back of your throat and you'll get a lot of throat hit you weren't expecting, and will cough, a lot.
Take long slower drags on an e-cig. Pull vapour into your mouth and then inhale briefly into lungs after that and exhale.
iii) the harder you suck on a cigarette the more 'hit' you get. the opposite is true of e-cigs (until you get into specialist coils) If you suck hard on an off the shelf protank2 on a VV mod you'll get a weak airy, insipid vape and will probably flood it to boot.
the smoke in lit tobacco is provided by fire. the harder you suck on the lit tobacco the more oxygen gets to the fire, so the faster and hotter it burns, and the more smoke is produced.
the vapour from an e-cig is produced by a heating coil powered by a battery. The harder you suck the more airflow goes over the coil and the cooler it gets. The cooler it gets the less vapour is produced and the more likely it is to flood. Again take longer and slower drags to allow the coil to turn more of the e-liquid into vapour.
It's entirely possible to build coils that will keep up, but you can't get them off the shelf (yet) and it takes know how to learn how to make them.
iv) sore throat. you will likely get a sore throat shortly after you start vaping. this is being caused by a number of things. Your body clearing out the accumulated gunk from smoking and the throat hit from vaping that you didn't get from smoking are the main 2. Lots of people might tell you you have a PG allergy and to use high VG e-liquid. Mostly they are wrong, something like 1-2% of people have PG allergies and should use high VG liquids, drink lots and it'll pass for 98% of people after a while. PG is in a LOT of stuff, from foods to cosmetics to medicines because so very few people are allergic to it.
Using a higher ratio VG liquid can help soothe a sore throat, as can lowering the nicotine % of the liquid but you're effecting a major change of habit going from smoking to vaping and you body needs time to adjust to that.
