i suppose 'addiction' and 'vice' are 2 different things here? 'vice' would mean a bad habit
which i still have some control over/ability to manage whereas 'addiction' in this context would imply a
'vice' which i have almost no/very little ability to control. in which case:
1. Smoking (Addiction - not going to kid myself, i ain't what you would call a 'social/casual smoker').
2. Mongering (Semi-Addiction - 3 weeks tops and i usually start to think of a punt
).
3. Drinking (Vice - no issues keeping sober indefinitely although the urge to have a single malt hits once in awhile).
