Xandemic: 2014-2016? Substance abuse during the 2010s.

I came across this term "xandemic" a year ago or so in a comment thread. When I think back to my college years during the 2010s I remember xans being quite prevalent late 2014 to early 2016. The context of how xandemic was used from what I remember was referring to people's high school time. Has anyone else come across this term? Opioid abuse got a lot of focus during the 2010s (still a big issue currently). Would it be accurate to say that Xanax was the other drug of the 2010s? Ecstasy was the drug of the 90s and LSD the 60s.
