Parental upbringing does obviously affect one's personality, and it is fair to say many addicts do come from dysfunctional families - https://www.healthyplace.com/blogs/debunkingaddiction/2020/7... ...
Sure; if the custom in your family when faced with problems is to drink or drug, then it won't be surprising if you take the same approach.
My limited experience of people from flawlessly functional families is that they tend to be - um - boring. I find people's flaws and weaknesses make them more attractive and interesting. YMMV.
Like having at least one parent with some issue that leaves the child with trauma? This is most people's experience?
