Dope Medicine is a drug used to quickly level up.
Dope Medicine is a drug people can use to get stronger instead of training or fighting demons. When used, the user's level increases by 1. After you reach Lv99, Dope Medicine will presumably no longer have any effect.
When you're level increases so does the potency of your Job's effect. However, you're stats will not increase along with your level, unlike the normal way of leveling up, leaving your base abilities weaker than those of a similar, or even lower leveled person. You also won't have the same amount of battle experience because you rushed to level up quickly instead of learning to fight more efficiently. It was first mentioned in Web Novel Chapter 99.
- There is a theory in the Other World that after one consumes 50 Dope Medicines, any more will have no effect.
