My friend is worried he's getting addicted to the calmness; is meditation addictive?

My friend feels so reliant on the immediate calmness from meditation that he panics if he misses a session. He's worried he's using it as a form of emotional suppression. Is meditation actually addictive, or is this reliance simply a sign that he is gaining tangible benefit for his mental health? His name is Jubin, DOB is 19th July 1993. He was born at 6:30 PM, in Chennai.
