Marijuana smoke gives me migranes

I live in oregon where marijuana is legal, And I'm fine with that. I just hate when people smell like it at the grocery store and other places. I don't give a shit what you do at your house, but it triggers allergies and migraines in other people. Take a shower and wash your clothes before going in public. I get instant migraines from marijuana smell and it is so bad that I get light headed almost immediately. I just want to be able to buy groceries without having to be crying all night from a migrane.
