No. 'Yes' if you want to be pedantic but no. Not in real world terms. You wont 'crave' a hit of the aul tea in the addiction sense. You're not going to suck cock for a mug of tea. It's a comfort, as Zippy said. A comfort anyone would easily, easily get over if forced to.

I don't even think it qualifies as a 'mental' addiction.
