There is no reason for an addict not to survive recovery no matter how long they have been addicted. Persons who are physically addicted to alcohol or other depressant drugs may not suvive abrupt cessation of use, but if they are gradually withdrawn, there is no reason for them not to survive recovery. Beyond simply surviving, recovery is always possible regardless of how long a person has been addicted. In fact. most addicts do recoverin later life if they didn't when younger, although some do remain addicted into old age.
