No, as long as they are not burning. They are plants and are actually very beneficial to the air and make it healthier to breathe. The only time that the active chemical in them is released into the air is when it is burned, usually for recreational purposes and sometimes by authorities destroying someone's crops hidden in the woods. If you are close enough to smell them burning then you can change the No to Maybe. There are a lot of different opinions on that as our differing laws around our country and the world will indicate.
