Lol, well I got bad news for you, if you’ve smoked any significant quantity of weed I can guarantee you that you’ve smoked several insects. But don’t worry, you would never notice and it would still be perfectly healthy (let’s not even discuss the odds of eating bugs when eating fruits/vegetables). I’m pretty sure that is a fruit fly so he will eventually fly away, he is just chilling there. Its hard to keep nature out of nature XD.
