Addictions to substances are very powerful.
Addictions to anything are powerful,and it doesn't have to be drugs or alcohol. People are addicted to risk-taking,gambling,food,and a bunch of other things. Each one is as powerful to the people addicted to it as alcohol is to a drunk,or heroin is to a junkie.
I know a man that was an only son,and he inherited hundreds of acres of rich farm land that had several houses on it. Some of it had been in his family for over 200 years,and other parcels were farms his grandfather and father bought up as families moved away,died out,or just went broke for whatever reason. ALL of it was paid for because his family didn't believe in borrowing money or paying interest. They did believe in lending money and collecting interest,though. They owned the local bank.
This man was a multi-millionaire in 1960,and may not have been old enough to vote. Hell,he even owned a country club and golf course,not to mention a stable of race horses and a private plane.
Today he owns nothing but one small house the courts let him keep,and he is living off of SS and driving a 10 year old pu. He threw it all away gambling. He would bet on anything at any time,but his favorite bets were long shots. It wasn't the money so much as it was the thrill of winning when he wasn't expected to win,and thinking that made him smarter than everyone else. He doesn't even have any friends because at one time or another he cheated every single friend he had ever had in various business deals. He actually bankrupted his father's business partner,a man who considered him to be like a son to him.
All this because he was addicted to the "rush" of winning,and like all amateur gamblers,he never saw the possibility of losing. Professional gamblers don't gamble. They play the odds and don't get emotional about it.
