I didn't get high for quite some time after starting to use cannabis.It wasn't that I wasn't smoking it right and the weed was good weed too.
The brain has cannabis receptors in it.I'm thinking not everyone that begins using weed at first may get these receptors up and running.It may take 1x 2x 3x or more differing from person to person.
When I finally did get high the first time I remember looking over at my friend,we were watching 'once upon a time in the west' and I must have had this chit eatin grin on my face because he looked back at me and smiled really big and said..."finally huh" and we just both cracked up.
Hey if you don't get high smoking cannabis don't worry about it.Just remember you can still go to jail for it whether you get high or not.
