If you think you may be brainwashed, you probably are. Actually, everybody is. Consider the morals you have. You were taught all about right and wrong but in reality, you're own perception of reality is your actual reality which is general reality to you.

Example:
As children, we watch the Disney cartoons teaching us morals so we all (excluding those who never watched them) have had a parallel moral indocterination.

There are many smarter people on this board than I and if anyone can add or subtract to this, that would be cool.

As far as pot goes, water can kill you if you drink too much too quickly.
