We had a quick scan of the wiki page. I don't think LILITH would approve a substance that would cause harm to its Outsiders, so the implant will block out any unpleasant effects such as losing cognitive function and muscle/skin breakdown and tumors. It will also block out the addictive effects, but if players do want to play out an addiction plotline we can say the implant glitched and couldn't stop that side effect.

In other words, this is fine to request.

Each vial will count as a magical item and be priced at 150. Since it's consumable, we can allow you to request 3 vials for the price of 150.

Hope that answers your question.
