OH my lord! Pretty much every bong store around your area. I would, however, advise you to go with the internet for your salvia. At headshops, you don't know if they are ripping you off or not and the prices are generall extremely expensive. Good luck.
Hey "drunkhippy" - I am from ottawa as well. I was wondering where did you get your Salvia from in Ottawa? And is it any good? Can I get some info on it please. Thanks.
seriously, if you can find a headshop, or even a good tobacco shop (the kind with waterpipes), theres a 70% chance that they will carry salvia
