Playing devils advocate for a moment it wasn't really as the enquiry regarded stats concerning second hand smoke in open air.
The truth is that most of the (limited) studies conducted relate mostly to outdoor areas where smokers gather, beer gardens, smoking areas in pubs, hospitals etc. and relate to particulate matter in the air which would be far cry from the discussion of second hand smoke at a music festival.
In my opinion which is based on no scientific evidence whatsoever I would say that unless you were stood within a few inches of a heavy smoker you would be far more likely to suffer adverse health effects from the dust and particulate matter stirred up by 150,000 people walking about.
1 sub, 1 second and 2 second subs. I wondered if Don Broco were still okay to go 4th down but JEW are 3rd down and Broco have done bigger tours then them. I don't know what would be ruling Deftones out from being added, i did think given they aren't reguslrs it was too soon. I presume if Weezer can announced Peace Hall same day which I actually think is risky then Deftones can. Spritbox 3rd down ST day and MM 3rd down. Bullet day.
