Micro-organisms which are beneficial to plants are not necessarily beneficial where human consumption is concerned. There exist two types of these micro-organisms.
Exogenous micro-organisms colonize in growing medium (rhizosphere) and on the surface of roots.
Endogenous micro-organisms travel by way of the vascular system and colonize within tissues of plants.
Experiment: apply baker's or brewer's yeast to the heating element of a cooking range. I will spare the unpleasant surprise. The burning of these micro-organisms will produce the same odor as burning hair or flesh. Those who have had this experience do not forget the olfactory insult.
This brings us to the burning of cannabis flower. Organically grown cannabis tissues will contain endogenous micro-organisms which cause the light and in some cases intense odor/flavour of burning micro-organisms.
There is a proper and decent way to serve organically grown cannabis. Active ingredient producing trichomes (resin glands) must be separated from chlorophyll containing plant tissues and plant fibers (hashish).
Personally, no matter which growing method is used I prefer to refine trichome heads away from trichome stalks, chlorophyll containing plant tissues and plant fibers (trichome heads for vaporization).
The inhalation of unrefined cannabis flower requires more elements which have no biochemical use in the brain's biochemistry to be metabolized by elimination. The added biochemical insults worsen dehydration, red eyes, dry mouth and fatigue (AKA couchlock).
The smoking of cannabis flower without refinement is largely responsible for the social stigma associated with cannabis inhalation.
So keep clean and know your inputs, no mystery sauce which must eventually be metabolized and eliminated by the consumer/patient. Thank you for caring and not joining the organic bandwagon along with the mistaken.
