The best way to attract non smokers in my opinion is through marketing, which is already greatly done, it just takes some time. With all the fuzz about facebook, there is surely a need for a different social media plattform, where freedom of speech is ruling and not the things ongoing on facebook.
Even on youtube with the adpocalypse and the ongoing censorship and being "non advertiser friendly" there is a definite need for something like the SMOKE network.
More and more people accept the great medicinal and recreational features of cannabis and these, smokers as non smokers, would love to have a platform to talk to each other.
Then it comes down to see a need, fill a need - SMOKE network, for smokers and non smokers alike.
