The short version
8 companies supply this market — a reasonable cushion if one runs into trouble. The brand price has fallen 52% in a year, to $0.8042 per gram — and generics that get this cheap tend to get abandoned rather than defended. Generic versions run $1.13 per gram — 2.4× cheaper. Put together: this looks like a healthy supply — the boring kind, which is exactly what you want.
