Fake hash is still very accessible, and is legal to purchase, as it contains absolutely zero cannabis.
The websites used to suggest adding JWH-XXX / XX-MDMB (spice), and so forth (these are synthetic cannabinoids, deemed dangerous. They are not like D8/HHC, etc).
Nowadays, there is no such suggestions (due to legal reasons, most likely).
It seems likely that these bars may be influenced by the synthetically produced cannabinoids, rather than the very dangerous synthetic "spice" products, as mentioned above.
The "terpene spray" also has some potential, as some suggest they have experienced terpene-infused hash.
The terpenes would most likely not be cannabis-derived, which would explain the low terpene content in the hash.
I have included a few screenshots below:

This is really nasty. It's lucky that the hash doesn't look very convincing.
