Now before I get attacked, I acknowledge that CBD is proven to treat epilepsy, so it's not exactly a homeopathy-level meme....

But, we gotta be honest here that this is probably mostly a placebo for most use-cases.
I've seen people claiming it will do everything from solve your depression to curing your cancer.
As far as I know, no compound ever discovered has been that widely applicable.

Additionally it's being marketed exactly like alternative medicine.
They put it in fucking ice cream.
If it actually did anything for most people it would be more expensive and wouldn't be infused into everything.
