You say it's just people who are "really far gone", but when I look at the type of marketing at CBD stores, it's marketed for nearly everything, so I suspect a lot more people are falling for this than you might suspect. Plus, any individual doesn't have to believe it's a "cure-all" - they just have to believe it cures their specific random ailment. I've seen it marketed to help with sleep, anxiety (despite it causing anxiety in a lot of people), depression, any type of pain you can think of, nausea, hoarders of chronic conditions, etc.

I agree with the top comment - I think it's great that we're starting to deal rationally with cannabis, but we need to be realistic about. It can be beneficial but can also cause real harms, especially in children and young adults, and cannabis use disorder is a real thing.
