I doubt it's fully useless, they just grab it to quick to use it on the frontlines, it's like using napalm for peace talks. After all, it was discovered by injecting rats with mustard gas. Kinda reminds me of the study that accidentally exposed the anti-tumor properties of cannabis, but that has been considered as trivial and shoved off the table. You must be very evil if you pass the glorious opportunities of the sickcare industry, sick people are there to be profited from honorably. Healthcare is so old-school, the health of the wallets of those above is way more important and they think that there are too much people of the inferior kind anyway, so who bothers.

Quite evident in the fact that you almost never hear of the anti-tumor properties of cannabis, all the while the National Cancer Institute states that it has possible antitumor effects.
