San Francisco is often in the news. Why?
I would guess because of all the technology companies here
Do you mean THC technology?
I do not know what that is? is that a euphamism?
THC? It is an abbreviation
Yes. I know. I do not what that company does. Do you?
I think they produce a product high in demand, with lots of health benefits
the product itself? or accessories to support use of the product?
THC has many uses, both recreational and medicinal 
Yes. I have heard. California is very supportive. Most of the US is not though.
