I have a good deal of experience growing both commercial hemp and marijuana outdoors and have seen many examples of glyphosate contaminated soils damaging Cannabis, as this plant readily absorbs glyphosate through its roots. In my experience all members of this genus are quite sensitive to glyphosate and AMPA, the chemical glyphosate breaks down into and that has a much longer half-life than glyphosate itself.
