"I just wish recreational pot smokers could understand what they are supporting," said Joshua Smith, natural resources project manager at the nonprofit Watershed Research & Training Center in Trinity County.

Actually, its those who support prohibition that cause this.
Just like the moonshiners whose stills would blow up,
start fires, be defended with machine guns, have poor
quality control, etc.
