Yeah, that is called withdrawal syndrome, when there are symptoms if the person stops using a substance. I think that's a problem caused by an addiction that interferes with a higher priority.

By the way, this is no joke and can lead to death depending on the severity.

For tobacco, I don't think withdrawal syndrome can kill, but it can last for 6 months according to a psychiatrist I know.

And about the criteria for addiction, in my country it is:

• manipulative behavior to keep doing it (it = using the substance or the activity)
• repertory restrictions (avoid doing other activities that the person used to do)
• harm in other aspects of life (like what we said before)
• keep doing it, even with those damages
