^^ He pretty much summed it up
Cannabis also feels very natural to me. You notice that it's a plant, a devine plant if you whish, unlike chemicals...
I LOVE the high, to me much better than many other highs.
Another advantage is that it doesn't mess with you heart, your blood pressure, your sleep or your serotonine and dopamine levels! Basically this means that after smoking DA WEED you'll sleep well and feel good and healthy the next morning (try that with coke, speed or xtc !)
One of the tricks is also in the dose. If you take too much you will get paranoid.
