this has been my theory ever since i noticed that i get higher inside.

when you are outside like there are wwwwwwwaaaaaaaaayyyyyyy more oxygen molecules then inside a house. so you breath in more oxygen which you body brain needs.
and outside, the temperature vary so that makes you go back to ur senses alittle more.
But when you smoke and you are directly nder the sun it will hit you like crazy! i guess bcs of the lightenig that is so bright and the heat that hits your head from the sun.

idk thats what i think.
