Yes. Father Satan encourages free will. Him and the gods’ true goal is to take humanity to god level. When you dedicate you are under his protection. It is up to you to continue drinking and smoking. If u think they are detrimental to your spiritual awakening then I assume you would wanna stop if not control it so it doesn’t hinder your spiritual advancement.
I assume you have already read templeofzeus.org. You should study it thoroughly. Once you dedicate you will be in Father Satan’s protection. Demons will offer assistance for your spiritual development as well and will guide you, teach you. Maybe one day you will realize what’s good for you and what not.
Hail Father Satan
