These drugs are like psychedelics. There are lots of non users talking about them like they know them but all they did is read stuff in popular media.

My friend cut usage after he lost weight and finds maintenance easy.

lol well you, on the other hand, sound like the real deal! direct personal experience unlike all those posers, right? except why do you keep bringing up your friend then?

This is a really stupid argument, your data point of "one friend" or even two or more friends with unspecified timeline is useless. The only thing that has any meaning is a formal study with a large number of participants over many years of observations.
