The social aspects of vaporizers probably depends on who you hang with. Everyone who I regularly get high with strictly uses a vaporizer when we are hanging out (or occasionally shares edibles). Not a lot of smoking going on. Of course, I am in my mid-30's and have friends of the same age or older, and most of these friends have stable jobs, such that spending $250+ on a vaporizer is a no-brainer.
The verb "vape" is what is commonly used with the people I know. It's not show-offy if vaporizing is commonplace. This is more recent, and I just said "use a vaporizer" in the past if I wanted to be specific.
Personally, I own both a non-portable vaporizer that can fill bags (Herbelaire) and a portable vaporizer (Pax). Both are used frequently and are easy to share with friends. I still smoke, but that is only maybe 10% of the time. I've been vaping for the last 17 years, starting with a home-made vaporizer made using a soldering iron.
As for alcohol: I enjoy it, but I rarely have the desire to drink it for it's intoxicating effects lately. I really enjoy the taste of beer (and wine is good too), but it's becoming rare that I actually want to drink one. What changed is that I started getting back in shape and exercising frequently (well, moderately). Due to being a new parent, I often get my exercise around 9pm-10pm as that is the only time that works for me. That means many nights, alcohol is just not an option. Also, I have been fairly consistent in eliminating unhealthy foods (I can count the number of times I have a sugary dessert in a month on one hand), and I've started to see beer as unnecessary calories. The fact that I lost enough weight to stop snoring is just affirmation that I should stick with this. I'll save drinking beer for social situations, rather than something I have with dinner.
