People often fall prey to addictions in this way because they lack control over their personal lives.

[he's only been working in the clinic for a week or so, but being the only doctor means you get a heck of a lot of patients with a heck of a lot of different problems. he's already seen a few for their addictions, be it alcohol, smoking or gambling. they did not like it when he first suggested they simply try not being addicted. that was a quick lunch break of googling addiction in humans in between stealing lunches out of the fridge.

he understands it better now, but still thinks it's a sign of weakness in those particular humans. harry watches it happen again, then frowns.] Mmm. I'm starting to get bored of this.
