I've never done anything that bad. Worst was probably asking my mom to give me money to buy a batch of poppies that I could repay later. I was running out and she knows I'll go into withdrawal without them, which would interfere with college. She had to wait to buy a new microwave because of it. I did pay her back, and more. It is typically I who give her money for rent as I still live at home. This was the only time I had to do something like that. I usually make enough to buy my own drugs, food, and pay an average of $150 a month + some work/chores as rent. Now I have a part time job(10hr/week, minimum wage) on top of my other income sources so it shouldn't happen again.
Maybe taking $4 from my nephew's piggy bank to buy cigarettes was worse, but he was also paid back with extra.
So the worst I've done is cause a minor inconvenience to my mom to get drug money. I guess taking that from my nephew without asking was stealing, but I put about $7 into it over the following couple of weeks.
No other cases of borrowing or stealing.
It might be different if I were addicted to heroin or crack, but I am addicted to opium poppies and cigarettes.
