I’ve noticed for the past month or so that my car seems to smell like weed. I have had the car for nearly 3 years and it never smelt like weed until recently and I don’t smoke, nor has anyone smoked in my car.

I had my car valeted and that seemed to get rid of the smell inside the car, however when I am driving with the windows open, I can smell it wafting in. There is no smell when driving with windows closed.

Any idea what this could be? I have checked the cabin air filter and that is clean and doesn’t smell (was only changed in October)
