I Hate Smoking

How come I can't enter buildings without a face mask? And, I can't get within 6 Feet of anybody without a face mask? How come the last two statements are enforced with all diligence, but not smoking laws? Which one has been around longer? Which one has more scientific backing for making a difference to the health and safety of society? This is just my little rant with the frustration with the world's current situation. Don't get me started on straws. We have to outlaw straws because they are littered too much. It takes 18 months to 10 years for a cigarette to decompose.
