Judge not, lest ye be judged.
In our current economic times, many of us are just one paycheck away from being homeless. Many of our young people are lured into a life of drugs by predators in schoolyards, wearing lots of "bling" and boasting about easy money.
It takes about a week to get a vulnerable person hooked on crack cocaine, and what follows is often years of slavery to pimps and pushers.
I live in a large city, there is a huge drug problem in my neighbourhood. Unfortunately, many of the dealers come from the suburbs to ply their trade.
Be thankful for what you've got. Focus on compassion, rather than judgement.
What most people need in this life are three things:
1 - a home
2 - a job
3 - a friend
Drug addiction is usually a symptom of underlying issues such as abuse, low self-esteem, and many other things.
Unfortunately many addicts are unable to find housing until they get the supports they need (counselling, detox, etc.) In my city, many of the detox centres have been closed due to lack of funding). Thing will probably get worse before they get better.
Thank the universe for your health and wealth and get on with YOUR life.
