Parenting in my household is almost nonexistent. Growing up I allowed to do whatever I wanted to which lead to hanging out with other misguided kids, me getting in trouble with the law on a few different occasions (prevented me from later joining the military), becoming dependent on smoking pot and using many other drugs from age 13-20, and later leading to severe depression and a nonexistent sex and social life.

Now I see my younger siblings starting to go down the same path although not as early as I did. They are now 18 and 17 and are allowed to smoke pot in the house (I never did but now my parents allow it) & have both gotten in trouble for possession of weed and paraphernalia. Communication between my siblings and parents is almost nonexistent. Everyone seems to be either in their room all the time or out with friends so maybe I'm coming across as too upfront when I approach them about this topic but I tell them to make the best of their time in school, don't hang with shitbags who are going to get you in trouble, and to save their money. I'm always met with, "Yep... we'll see." or a "everything is going to be fine" sort of response.

I'm at a loss on what to do or even if I should be doing anything at all. But as an older brother and I don't want them to have to go through the shit I went through. My parents don't seem to bother with the situation. Parents age gap is almost 15 years and typical husband/wife scenario with husband working overtime still to this day and almost 65 years old while wife works part-time at department stores. My dad's daughter from a previous marriage wound up marrying some dude 20 years older than her. I feel like I care more about their future than their own parents.
