My nephew is 25 years old, and his Mother, my sister has told me that she will do anything for her only child, whether it is right or wrong.
My nephew comes and goes as he wishes. He does not have a job and has only a high school education.
My nephew does no chores around the house, and he stays in his room all day.
I had advised my sister that I found a weight scale in her son's car when I was cleaning his car while they were on vacation.
I also found a cut stray with some black residue in my Mother's car when she loaned it to her Grandson, my nephew. My nephew was also involved in a car accident with her car, and he denied everything, until the person he hit filed a claim against my mother's car insurance.
My sister even suggested that my parents may have caused the accident since they are elderly, and may not have noticed that they damaged their own car.
My nephew totaled my sister's car, damaged my parents' car, and then my sister bought him a new car. My nephew then again got into an accident that caused major damage to his car. He claimed that a garbage forklift impaled the trunk of his car.
His Grandfather, my Father, and his Uncle, my brother both died of COVID-19 in January 2021, and my nephew never came home when we were all sick with COVID-19, and he did not even attend their funeral.
We all live in one (1) house that belongs to my sister, for the past 15 years, so my nephew grew up with me, my brother his uncle, his Grandfather and Grandmother.
My nephew and his family are currently on vacation for a relative's wedding.
Today, while gathering laundry, I found small packets of what appear to be mini weight scale (grams), designer drugs and pills and a crack pipe among his belongings.

My sister appears to believe that my nephew is an adult and is entitled to his privacy. She also gets very defensive and upset when I mention anything about her son's behavior and symptoms of drug addiction.
My sister would be very devastated to lose her only child. She may even commit suicide. She, too has had to suffer from pain, sorrow and sadness from losing her Brother and Father from COVID-19. She has also been drinking constantly (vodka and sake) to take away all of her stress and hopelessness.
Her son also suffers from depression, and may or may not currently be taking anti-depression medication. He is not violent, and as far as I know, he does not steal from any us.
My sister has tried occasionally to have family counseling, however the counseling has been far and in-between, inconsistent and by telehealth.
My nephew is now away from home for many weeks, and sometimes months. My sister gives him money when he is home, and then again he disappears for several weeks or months. She also buys him clothes, shoes and his favorite food when he returns home. She gets so excited when he is home, that it is like she is rewarding him for coming home.
I know that my nephew's brain has been affected by his drug addiction, and I believe he is dealing and selling drugs to support his addiction and get his next fix.
My Father took care of my nephew since my nephew was a baby, and he loved my nephew very much! My brother lived with my nephew for many years when my nephew was growing up, and he was very close to my nephew. For my nephew not to attend their funeral, or at least call, support or help us, check-up on us, or be there for us when we were all sick and suffering from COVID-19, was very hurtful. My nephew was the only family member not infected with the virus.
My mother is devastated from losing her husband and son from COVID-19, and her two (2) younger brothers, all within the past year in 2021. She loves her grandson very much, and this behavior is constantly breaking her heart!
I desperately would like to know what to do to help my nephew before his drug addition kills him, and destroys our family!

This behavior has been going on for over three (3) years. Please help us before it is too late!

Sincerely, Ricoventures
