"Not that I have any experience of any other drug then alcohol."
Then you don't KNOW, do you? And if you lack knowledge of marijuana, how can you truly hold a position such as to ban marijuana, with any kind of authority?
Trying to say this as kindly as possible here: If you don't KNOW much about something, you should either find out (and heeding what you are told is NOT finding out), or refrain from forcing your political will (by supporting a ban) on those who DO know more about it (marijuana) than you do.
"But documentarys (both positive and negative propaganda) I have seen dont bring me to think that people that smoke marijuana is that aware in their mind."
You admit that you fall for propaganda? Without even trying to find out if it's true or not?
Well at least you're honest.
Seriously, I think I should be left alone, without fear or threat of force, to engage in whatever peaceful and noninvasive activities I choose. Especially from force that comes from the will of ignorant "sheeple" who listen to too much PROPAGANDA without questioning.
If that sounds harsh, then try to find a way not to make the shoe fit.... Remember, questioning what you are told is often how you learn things. At least, try to PROVE me wrong about pot, if you can (i.e. question what *I* say if you like)....
(BTW, honestly, do I strike you as someone "not that aware" in my mind? What if I told you I was a little stoned right now, and often am when I write many of my posts?

Not to brag, but I think I'm pretty lucid most of the time, even if you don't happen to agree with my positions on things....)
