 ### Disclaimer
 Drug abusing, dealing, smuggling and organized crime damaged and still damage many cities (like mine...). Minetest is just a game and Drug Wars doesn't encourage in any way illegal acts related to narcotics. Do drugs responsibly.

+Using drugs leads to immediate buffs and debuffs and aftereffects. Everytime a player consumes any drug it will, more or less, increase its drugs addiction, which will progressively cause damage over time, reduced drugs buffs and harder aftereffects. A player's addiction will reduce gradually while not using any narcotic.
