In deed a sincere concern. Yet I do think that growing weed in an higly controled environment could provide far better quality. Besides that their are many ways to experiment with the wide variety of cannabinoids. Currently in the recreational growing sector the main focus is extreme high percetage of THC which in the long run don't really benefit people.
So don't get me wrong, I agree with your point of view. I think what I'm trying to say is that it also has potential positive effects given they are executed in the right way. The last is highly doubt full given todays situation with big pharma, which is money over people.
