How would you beat an addiction to something you have literally an endless supply of?

How would you kick an addiction to something that you had endless access to at any time, in any place.

—Day or Night. You don’t need to call your dealer or wait for the drugstore to open. It’s always immediately accessible to you, whenever you “need” it.

—In public or in private. If you’re in public and you “need” it, you can just go to a bathroom stall.
