It's a bit strange what's happened to me recently, and you saying you don't drink alcohol reminded me.
I've been writing a lot of amazon hubs about gardening, they're my niche, so to speak.
Anyway, on browsing their site, I realised they sell a lot of certain flower varieties, so instead of writing about annual or perennial flowers, I chose to write about the ones they sell most of.
The first I chose were poppies, and the first thing I did was look up poppies on google for interesting things to say about them, only to discover that roughly half of all poppies are opium poppies! I thought they were some rare and foreign variety.
So now I'm advocating drugs whether I wanted to or not.
Today I thought, I'll write about Morning Glory flowers (there was a lot of them) and would you believe they also have a drug connotation! Jeez! That's probably why they sell so many!
