The Issues They Raise are Contamination Related
not cannabis related. Clean cannabis doesn't cause lung problems or any of the other issues they're afraid of. Contamination is what causes problems. Excess nutrients, pesticides, miticides, hair, dust, pollen and on and on. These are the problems with the 'available' cannabis.
A week of clean cannabis, the quality I grow, and these naysayers would definitely sing a different tune about 'cannabis.'
