I smoked weed for nearly 20 years and never did it in public. Partly because I knew the main employer in my town drug tests their employees regularly but mainly because it doesn't help the general public's opinion.

If the only people that most of the population encounter using an illegal drug are ignorant wasters then it harms legalisation efforts.

But there are so many pathetic idiots here who have nothing going on in their lives that need to impress others by sparking a joint in public.
