I should probably use a throwaway, but I am not scaed.
During the peak of my very long addiction, post retirement, I was spending $250/day - not counting the habits of friends that I helped to feed.
The only difference between what people call a junkie and myself is that I can afford it. That's also the reason why I was able to get adequate assistance to minimize the harmful behaviors. Err... I am on Suboxone, and probably will be for a very long time. I used for 35 years.
Anyhow, it can be expensive. Users equate use with life. Life always finds a way.
