I wonder if this is skewed by the states where marijuana was legal/more accessible during that time window. Colorado was the first state to legalize it and is also the state with the lowest BMI.
It has to be said that Colorado is a state known for outdoors culture and people are naturally more inclined to be physically active with more exuberant nature outings nearby.
Depending on the level of pedantry you want you could argue for either. Washington's measure went into effect first, on Dec 1st, 2013 while Colorado's went into effect on Jan 1st, 2014. Colorado opened retail shops that same day though while the first shops didn't open until July 2014 in Washington and they had a lot of initial issues around licensing leading to slower expansion.
Sure, but in reference to the comment "because of the time difference" it seems pretty obvious he was referring to time zones, not the dates the laws took effect.
