If you think about it, being sober can be just as much of an expirience as being stoned. You've probably already thought this, as it seems like a natural path of thought for a stoner after taking a break from a lot of smoking...
But if what if we were born stoned? And a drug like marijuana made us sober instead? People would still smoke it... We can't really understand what it would be like to grow up stoned, our perception of it would be quite different, but the fuzzyness would definately be noticeable after smoking some Clearminding-drugs. And if there is a way to cloud your mind, is there a way to make us even more clear-minded? Psychedelics do this in a way, but they cloud quite a lot at the same time, certain mental abilities are enhanced and weakened.
After smoking a lot, I really do appreciate being sober like you said... I think when I have the finances i'd like to keep it 50/50.
And then draw out some sobriety time for a tolerance break.

I really need to do some more psychedelics... Enlightenment isn't just a whimsical fantasy.
