I've had em since about 3rd grade. flash foward 1x years and many pounds of weed later, I will still say weed does not help. Me at least. It makes it easier to chill out though, and most times i often just toke up and drift to sleep when i have one. It sucks when you have the multi-day headachs though.

On a side note, i get burned often at work, and toking does help with burns a shit ton.
