Cannabis, and I assume primarily THC, is a mental amplifier. It focuses and stimulates specific functions depending on the brain and bodies current condition. Like anything, too much can be damaging, even permanently. However, if the brain and body are not already inflicted then building up a tolerance to high daily consumption can be used to achieve certain focus states or relaxed states. 
An easier way to absorb this is:
>Nancy smoked and her heart beat too fast and scared her
>Pepe smoked and made a 40 pack of tendies from the freezer
>Charles dabbed and worked on his programming projects for 10hrs straight while sampling music
>John smoked casually until the herb tapped him on the soul and said 'Man, why you treat ya body like shit and ya mind suffer all d'time?'
gpt
oh and,
>Jen and Tom smoked and watched a horror movie until they had sex in the dark for hours, followed by coffee
