Not surprising when you consider that the impaired executive function associated with ADHD (and mitigated by medication) is known to frequently manifest in the form of weakened self-inhibition.

Anecdotally speaking, whenever I personally go without medication, I am endlessly distracted by even the most basic urges (i.e.: hunger, exhaustion, arousal). Even being slightly peckish would leave me growing increasingly irritated and uncooperative. I've never smoked, but you wouldn't know that by looking at my unmedicated habits -- taking breaks every 20 minutes to satisfy some random urge before I inevitably start losing my head.
