The lack of consequences really kills the game. It starts with there not being a cost anymore for letting Volo do brain surgery with an ice pick and culminates with there not being consequences for snorting and using tadpoles despite everything the game and common sense tells you (having to roll once to prevent a appearance change does not count).
The entire premise of the game is that the tadpole is a danger and you need to get it out, bzt in the end you should do the opposite because they are no danger at all and purely benefitial.
I blame it on the Emperor and his last minute addition to replace Daisy (Emperor is not in the artbook, the description your companions give you sound more like Daisy instead Guardian, Omellums quest makes 0 sense now) which likely also included the consequence free tadpoles.
The Emperor either needs to be removed or completely rewritten to add more Daisy content (danger of succumbing to the tadpole, consequences of tadpole use, a battle for your trust and your mind between different actors)
