Really sorry to hear that.
The amount of people smoking weed and driving in my area seems to be increasing. When I'm driving, it's at least once a day I smell the stench of weed being sucked into my car. Numerous times I've been stuck in traffic behind a stoner and the stench just pours in.
This is my experience and I don’t like it either. I am sober driving miles on packed LA freeways, and I find it hard to stay super focused to avoid accidents in stop and go. Smelling pot from a car around me daily is not a good feeling.
