I've found that many if not most of the life long pot smokers have developed a paranoia, not of getting caught, but of seeing themselves as a sort of black sheep, but casting the blame on others. To me this is not so much of a mental failing but more of a conscience eating away at their stubborn pride. The only difference between recreational pot and cigarette or alcohol, is the self justification that pot is less harmful. Just because it is not addictive like cigs or booze, does not mean there is not a psychological addiction to a frame of mind. That exists. And that original intent of mind/spirit expansion becomes a one way fast trip deep into self. But quite frankly, anything that becomes a crutch, be it healthy or otherwise, just means the person is a lesser being than they could be and has basically made their crutch an idol that comes between them and their ability to channel God. The older we get the more we need our wits to be clear. The world has many ways to drag us back down to it's level.
But again I stress, this has nothing to do with non THC industrial hemp and the oil, food or whatever derived from it.
