Expert Insights

I never fully understood the link between addiction and homelessness until I moved to San Diego for work. I’d seen homeless people in my home state, but never anything like this. The bridges downtown were covered by tents that were occupied by multiple people (and usually a dog). In a short matter of time, I saw my share of drunken fights between homeless men, I saw a co-worker assaulted by a homeless man who was offended she offered to buy him breakfast instead of giving him cash, and I learned how to step over two men who constantly passed out in front of our office door right before lunch. But I was also very confused as to why so many addicted members of the homeless population refused to take advantage of the wealth of free treatment and recovery services offered by San Diego and California as a whole. I even asked some generational locals about it; I was told there are “too many rules they’d have to abide by – they don’t want to do it.” Despite the beauty of San Diego, the willing nature of the public to help, and the hundreds of millions of dollars poured into helping a population that desperately needs it, addiction rates and homeless rates never improved during the nearly five years I spent on the West Coast.
