I'm not going to tell you what you should or shouldn't do. If you want to do it because you're bored, I don't think that is necessarily the best reason to start, but whatever, you're an adult and you can make your own decisions.
But in case you sort of have your mind set on it and will do it anyway, obviously first be aware that nicotine is really addictive. There are plenty of places out there that have 0 nicotine options so maybe start out with that, that way if it winds up being a passing curiosity, then no harm done. I use v2 standard e cigs and can vouch for them being a good brand if you just want to try out some basic analog style e cigs. While I do use cartomizers that have nicotine in them, they do offer several versions that run from 0% nicotine to 2.4%. The v2 Standard kit is $40 for two batteries, a charger, and 10 cartomizers. Again, I would recommend starting with 0% nic first which are available in the cartomizers themselves as well as the liquid ejuice.
Also as someone who was a non-smoker before I started vaping, some might think what the crap, but honestly it has helped a bunch of my health issues which I don't need to go into here. However I do have sleeping issues, especially with getting to relax at night and vaping has definitely helped me personally with that. I also usually feel really stuffy in the morning because I have a lot of allergies and vaping clears up my head really quickly. Again, I still recommend starting out with 0% since it seems like you're more curious to try it out. If you're still wanting more from the experience and decide to go with juice that contains nicotine, again you're an adult and that's your decision.
