OP of course you can. I recommend you don't start off on the big boys (mods)
I didn't have one of those but they are for cloud chasers (more vape clouds/smoke)- and more experienced vapers - not what your looking for. You're after the throat hit.
You need a beginners one - There are lots, kangertech & Aspire etc.
I recommend Aspire or kangertech cartomizers/tanks along with the same brand or any 510 thread 1100 mah battery capacity. That's a good starter kit. Don't buy the cheapy £5 650mah small battery ones in shops, as those tanks you get with those don't last long and leak like hell.
Steer clear of buying batteries on eBay - lots of fakes around. Only buy from from eliquid websites. Good websites I recommend are: eliquid world, go-liquid, total eliquid, Shop 2 stop.
You can buy your juices online too.
However if your going to go into a actual vape shop then prepare to pay a little more & completely ignore what I have just said above 
You need to start off on 18mg nicotine, that's enough.
I started on that and managed to get down to 6mg.
It's so easy to quit on the ecig!
With the juices you will notice the contents: PG (propylene glycol) & VG (vegetable glycerin)
PG is throat hit - VG is vapour/clouds. PG has a tendency to irritate the throat, it did mine, so a 50/50 PG/VG is great. But you might want to start off on 70% VG first for throat hit n see how you get on with it.
With all e cigs you need to change the coils around every 1-2 weeks, you will know when it needs changing because it will start to taste a little burnt, or vapour production will be low n it just won't feel right. You can buy the right coils for you tank in packs of 5.
Ok, well I wish you well on your journey, you must switch as I think you will be pleasantly surprised.
I would also like to say I enjoyed writing my essay on here... bye 👋
