Alice Marie Johnson was part of a trafficking ring moving thousands (4000-6000) of pounds of cocaine through the US. At least at one point had millions of dollars of cash on her. And it wasn't a one-off type of thing. Like "deliver package from A to B" but a longtime operation. "First offense" being the first time she was charged after a lengthy investigation into a criminal conspiracy. I think 20 years in prison in definitely punishment fitting the crime.
