420 mean weed ect. so my guess is that's what she is talking about.
I've always assumed that it meant that they didn't mind people that smoked weed, I suppose it could mean that they smoke weed as well.

I would assume its something to do with Marijuana use. Either to say that she uses or that its alright for you to use.
However when in doubt ask her. She should be more than willing to tell you.
420 is said to be the international time to smoke pot. It has been said to have originated from police code for a marijuana bust but this is untrue. Some say that waiting until 4:20pm to smoke marijuana enhances your appreciation for the 'treat' :) Outdoor growers typically plant their outdoor crop on or around April 20th (4/20), which is said to be 'Stoners New Year.'
So 420 friendly means that she may not actually use marijuana, but she is ok with marjuana and its underlying culture.
