I wouldn't call it alcoholism, but I do think there's too much emphasis on alcohol in team building. Getting trashed with your team and making memories (or lack thereof) is kind of a fast track to becoming tight. But there are healthier and better ways to do it.
This is 30+ year old me speaking, but mid-20s me would be out until the early hours of the morning with the rest of the team on a work night, and I loved it. But now that I manage a team, I pretty much never make alcohol the focus of any company event - not really healthy or something I want to be actively promoting to employees. I guess I'm a bit of a puritan now.
