There's literally a picture of him with a crack pipe in his mouth. He's factually a crackhead.

Also, you might want to avoid such categorical statements, because one of Devon Archer's business associates has recently flipped and provided his emails as well. Those corroborate the "China" arc of the story. Note that the story you linked is a repost of a WaPo story, which itself has no on-the-record corroboration from ODNI, FBI or DOJ. So I'm pretty sure it's fake news.
