I am a small online business owner and am thinking of investing in an online headshop that sells waterpipes, bubblers, and other smoking accessories. I've quickly learned that the big advertisers (google, bing, yahoo, facebook, etc.) frown on advertising anything that has to do with drug paraphernalia. My question is if anyone has some advice on advertising an online headshop that sells waterpipes and other smoking accessories? Thanks for any advice or constructive feedback.
