Sure we can. It's pretty simple. Don't violate someone else's pursuit of happiness for your own carnal pleasure. Pretty simple. Don't voluntarily inhale, ingest or inject substances that may have deleterious effects now or later. Again, simple. If any of that's too difficult to avoid, there are consequences. It helps to know that up front before voluntarily filling one's life with inconvenient obstacles and detours. Individual choices matter. Always have, always will.
We don't create unsuccessful people. They volunteer.
