Has anyone noticed the amount of drug addicts and unusual people now around the suburbs?

I keep seeing men and women who look like they have been smoking the grass off the side of the road or on acid trips, as a girl i feel unsafe even in public areas when i get asked random questions about my dog or what my name is and where i live by a man sitting on the side of the road on someone property who is clearly on drugs. Why does this feel like it has just happened this past year? they are making suburbs unsafe and people uncomfortable.
