> It's a type of team building, improves employee morale and humanizes management. All lead to improved productivity in the long term.

Yes, but the important distinction is that its intention is to bring people together face-to-face, not isolate them to their desks for continued work. Just because the end goal is "productivity" broadly speaking, doesn't mean the mechanisms are socially/morally equivalent.

> I doubt anyone is forcing the employees to take the stimulants.

I agree, and I hope my comment didn't imply I thought that was the case.

I don't see how offering nicotine (or caffeine, or amphetamine) is morally wrong if it's not mandatory. In fact, given 2 companies that only differ in what they offer - free beer on Fridays for 1 hour or free stimulants all the time - I would choose the second one in a heart beat. Many people wouldn't, and that's their choice. I just don't see how one approach is better ethically than the other at all.
