Is it possible to actually mine this coin (yet or ever)?

You should have gotten email after signing for the airdrop related to the signup form.
I think you can Maybe still edit it, although i am not sure about it.
If you are having a hard time finding your profile, it can be found from here: https://bitcointalk.org/index.php?action=profile;u=912366
I hope you get it solved.

I registered for the airdrop. Thank you very much. Good look with your project

I have the same problem. My Bitcointalk profile URL does not appear in the airdrop form.

when this coin is supposed to be launched exactly? i see there is some hype around it and dev is active, i also like the airdrop, but i think every announcement that is made too long before is not going to work

Hii lysergion dev, you said we will receive our airdrop and signature bounty token by August 19 but today is 20th.

Pls you need to update us and let us know if the project is still active or not. I have been wearing the signature on my profile but I'm not sure whether this is still active or not   

Would be nice to get some feedback.

You will get the airdrop by private key (on PM i think), but if you have not, you will not get it.
Airdrop closed on 19th of August, therefore not any new registrations into it are accepted at all.
Feel free to join the discord if you have anymore  questions about anything related to Lysergion or harm reduction about psychedelics overall

Airdrop is closed, but there has not been any official announcement by the dev so far.
