The only thing I have ever had weed "Magically" fix is being bored or sober.

Weed also increases your heart rate when you smoke. So a faster beating heart and lower blood pressure both go with a blunt. Good to know when mixing with another activity.

Also as MJ is said to be connected to eye health it may be affecting your vision slightly.

Oh and the "Elevator" thing is dangerous as are "elephant" hits. You know when you take a hit, hold your breath and a friend squeezes your chest.
