Hmm- not to go too far off on a tangent here, but yuo've gotten a lot of vape-related advice already, and tricking is not my gig, so...
I do have some advice for you about games. I'm just old enough to barely remember the advent of computer games. I was fascinated by them from the beginning. Competitive online gaming began in 1993, a little late for me (apologies to Philip Larkin and the historical record.) I first played a competitive online game in... early '97 I'm pretty sure? I would have been 25 at the time, and was a belated CS undergrad. It's probably a very good thing that I was too old and too busy to completely devote myself to Quake, as I might have if I had been born 10 years later.
That said, I got pretty good at Quake. Not good enough to play professionally, but good enough that I eventually played casual games with the best players in the world. Who stomped me in a very lopsided fashion (people often fail to appreciate how big the gap between being very good at something and being the absolute best at it generally is, not just in video games. Competing with the very best at something you're merely very good at, especially when there's no real room for excuses, can be a valuable and eye-opening experience. It was for me, at least.)
As recently as a few years ago I worked in an animation studio, mostly with people much younger than me who blew off steam by playing TF2 in the office. I started playing too, and because of my experience with Quake and the lack of matchmaking in TF2 I was ridiculously dominant in pubs within about 100 hours of picking the game up, and eventually dipped my toes into comp play. I'd be very surprised if I weren't the best Scout NA over the age of 40 for a couple of years there, especially when it came to raw DM. Again, I eventually wound up playing with the best players in the world, even if just on DM servers, and again they were a lot better than me...
I played a bit of LoL a few years ago, 'cause a friend wanted me too. Didn't get very good at it, but I did at least watch some SoloRenektonOnly and get a feel for the game as a whole. And I at least got a feel for the outrageous toxicity of the player-base

. Then, last year, I wound up sitting on my hands for a while as various things worked themselves out, and played some Dota 2. Well, I am pretty sure that if I put the time in I could get as good at MOBAs as I was at shooters, which would probly make me low-mid-diamond at LoL or 5k at DOTA. I think I'm too old to want to bother bother now though.
The thing is, one of the reasons I could always get good at these games is that I learned to master my frustration with them (that was, perhaps, easier in the days when every teenager you played with didn't think he was going to make millions playing the game, and that you were the main thing holding them back, because ELO hell right?) without discounting it. I learned to analyze my play critically without becoming too invested in it (and while I played casually, that doesn't mean I didn't spend hours watching replays of my play in slow-motion looking for flaws.) And I learned, eventually, to limit the degree to which I blamed teammates for my own failures. (None of us are 100% on that one, I'm afraid

.)
There are a _lot_ of lessons to be learned from playing games, and maybe especially MOBAs (though why you play LoL instead of Dota is beyond me.) If you spend a lot of time playing them at your age how you approach them might significantly shape how you approach other things later in life. Some people think video games are a waste of time- I'd say that given the complexity of a game like Dota or LoL it's an opportunity for you to build character, or not.
Let me ask you a question, and it's an important one. Do you believe in ELO hell? When you get frustrated, and want to vape to relieve it, is it frustration over your play, or frustration over your teammates play? Frustration over the former has to be managed. Frustration over the latter is nonsense in PUGs- get better if you want to be matched with better teammates.
Do you yell at teammates who are doing badly, or do you try to keep their spirits up, and help them if you can? If you do the former just switching to doing the latter will raise your ELO enough to match you with better teammates- it's a virtuous circle. Staying positive, and quelling negativity on your team is worth a few hundred ELO points, at least.
I won't encourage you to vape or discourage you from vaping. I'm also not going to tell you not to play LoL (well, you ought to play Dota, but whatever.) I will encourage you to make the most of the time you spend playing team games with random toxic strangers, and I'm inclined to think that you ought to reflect seriously on your reactions to the game and what they mean. Vape if you want, but first deal with the underlying questions. Real life can resemble MOBAs a little more than is comfortable (though you don't get to tell people to kill themselves, for the most part, without HR getting involved.)
