While I'm not a fan of constant exposure to the smell of Cannabis at home from people growing it without proper odor control in my neighborhood and people smoking it everywhere, it's highly unlikely that your anxiety is from secondhand exposure to cannabis smoke. There are several good studies about second hand exposure, like https://pubmed.ncbi.nlm.nih.gov/25326203/ https://pubmed.ncbi.nlm.nih.gov/25326203/ (and related listed) though not without limitations and not fulfilling all science best practices that come to the same conclusion: You basically need to be exposed to secondhand smoke in an unventilated room for hours to inhale enough active ingredients to have minor behavioral and cognitive effects from second hand exposure. Without giving you medical advice, I'd probably consider talking to a psychiatrist if you obviously have considerable discomfort from the smell of cannabis. As someone with PTSD who sometimes got flashbacks and anxiety from smells like charred meat, maybe there is an (un)conscious event in your past or youth that you connect with the smell of cannabis that makes you this uncomfortable. It's worth checking out, it got significantly better for me from therapy and "unlearning" that connection.
