Addicted.

To apply one’s self habitually; to devote time and attention by customary or constant practice; sometimes in a good sense. They have addicted themselves to the ministry of the saints. Corinthians 16:15. More usually, in a bad sense, to follow customarily, or devote, by habitually practicing that which is ill; as, a man is addicted to intemperance. To addict one’s self to a person, a sense borrowed from the Romans, who used the word for assigning debtors in service to their creditors, is found in Ben Jonson, but is not legitimate in English.
