Endorphins aren’t opiates. I am not familiar with any research linking chocolate and idiocy but I have surely seen a lot of idiot pot smokers.
I don’t make a distinction between one “Mood Altering Substance” over another, regardless of whether or not they are Illegal or Common. If One “Mood Altering Substance” is grounds for termination or not getting hired, then ALL “Mood Altering Substances” should be treated equally.
If your “Mood” is altered as a result, then there is NO DIFFERENCE, your “mood” is still Altered regardless of the substance you took.!
