Im new to vaping and unfortunately all i have experienced is coughing, spluttering and discomfort...i picked up the subvod nano by kangartech..... is this normal for beginners
To a degree it is normal. Vaping is categorically different than smoking a cigarette. It is even rather different than puffing on a pipe.
@RoseJ suggested checking out a link on inhale technique. I second her pointer to that. Vaping takes a user learning how to do it.
As a beginner, I would also possibly suggest a different starting kit. Any eGo type battery, especially an eGo Twist type at say 1100mAh and a reasonable Evod style tank would get you started. It may in fact be, the type of kit, all you ever need.
Here are a few:
MadVapes Majestic ARO Kit | Madvapes

These are out of stock currently. They can though provide you with examples. I use both the ARO and T-Dux 3.0 tanks. Both do very well. They offer good flavor and from time to time you get some plumes of vapor.
These are also Pyrex glass tanks. That means you could use any flavor you want without much concern. The epoxy compound used to insert the glass does wear away after 6 months to a year. And that's no real hassle.
These tanks remain priced under $10. I pick up a five pack of them here and there once in a while. Presently, I know where I may find ARO & ARO II tanks for $1 a tank.
Coil heads for the tanks are not expensive either. Normally under $10 for a five pack. They're single coil heads and can be rebuilt if you really desire. I get a head to last about a month before it needs serious cleaning. Rinse between refills.
After a dunk in vodka and rinsed clean after a month, I can go another month. Then, I may rebuild or just look to order new heads. A five pack of heads then could be said to get me through about 10 months, maybe a year if I rebuild a bit.
The T-Dux heads can be rebuilt as well. From what I understand of the process though, just as far ahead to order new. They run just a bit over $10 for five pack but they are dual coils, so cost more. Do not think I've seen any vendor go too far over $15 for a five pack.
