I actually did some calculations in the vain a few weeks ago with depressing results:
Cocaine: approx 44k P.A
Alcohol: 13.9k
Cigarettes: 3.8k
Caffeine: 2.3k
= £64k per annum on addictive substances
If I factored in food (an addiction for me) then it would be significantly higher.
Repeat that over 20 years (minus 4 years of sobriety) and that's over £1 million.
It's not just affected my life, my health and my ability to buy material objects but also taken a dent out of my charitable contributions. There were so many good things I coul've done with that money but, instead, I and others have suffered.
