What a lovely upbringing to be able to talk about years of drug use at age 19....
Consider your family fortunate, and be grateful if they have no stories or experiences with drug and/or alcohol problems.
I personally know many people who got addicted to drugs and/or alcohol at a young age, stopped, and serve as examples of the benefits of clean-sober lifestyles.
On the other end, Sunday night I listened to stories told by two men I met just a few weeks ago.
The elder is 88, and celebrated 34 years of sobriety. IOW he got sober at age 54.
The younger was just 82, and has only 7 years sober, meaning he did not get sober until age 75.
The difference these days--powerful drugs can do you in much faster, than the early years of mere drinking problems.
Me, I made it to age 45 on drink alone, before stopping.
For those of you fortunate enough to control your drinking, I say cheers !! Enjoy.
