I appreciate both of your contributions to this thread (and others). I want you to know that I once was that tenant with a baby and young child in a rented house. After neighbors in the basement moved in, we began to wake up most mornings to pot smoke rising through the vents in our units. I complained to the landlord but he did nothing. My only response was to hand him a letter of notice to vacate. He wanted me to stay, but didn't have the intestinal fortitude to take action that would help me protect the air I and my children were breathing.
Today I am the next door neighbor to a house full of people who are not allowed to smoke inside their house, but they can smoke on the front porch or out back, and I smell it, even when the windows and doors are closed. Because we own our houses, I don't have a landlord or law enforcement to help me.
And my elderly neighbor, with the oxygen tank, has a restriction: smoking around her and her tank is a fire/explosion hazard I think. I believe her illness is because she was exposed to too much smoke in her life, so "smoking" marijuana isn't the answer for her (maybe someone will take her some brownies).
