A society hindered?

In The Botany of Desire, on the chapter regarding Marijuana it was said that "cultures tend to be more wary of these plants, and for a good reason: they pose a threat to the smooth workings of the social order"--a statement that is incredibly subjective. To begin with, who determines what deems a social order as a smooth working model? The social order is intricate; interlaced with people all embodying different ideals and preconceived notions on things--to make it universal, and fit it with a standard would be to ignore the uniqueness of it, and consequently disregard our basic freedoms of thought. Fitting marijuana with the label of "bad" or "unproductive" is to label it preemptively and deem it unworthy of a society that functions to our liking. Such preemptive measures are limiting, and in my opinion restrict us mentally. Those who label marijuana as destructive and confining are actually limiting themselves in the process. While by no means am I telling people to smoke marijuana, but I am telling people to broaden their horizons mentally. Judging a group of people, and predetermining their productivity based on the use of a recreational drug is no better than ruling out theories before testing them. Marijuana just suits a different demographic of people, but that doesn't mean that those people are any less worthy of a "working societal" model than those who chose not to engage with drugs. I feel like the moment we think we can decide who belongs in a society, and who doesn’t, we become the monsters we are so worried drugs will transform us into.
