Hello, im new here on grasscity and im not sure if this is the place to discuss this but ill post it anyway You see, i recently bought a bong from my friend and it came with a stem and no bowl, so seeing as i had to make a bowl out of something i had only 1 option. A old rusty ratchet head (at least i believe thats what tool it goes to, maybe its a socket wrench i really have no idea), so before you start dogging me for my idiotic choice of a bowl i would like to state that i have a very limited financial and supply situation, so this was the best i could do(and also the bowl fit quite nicely into the stem and provided a nice look). Now onto my real question, could smoking out of this rusty bowl lead to any health problems? im not sure if you can get tetnus from smoking rust but you can never be to careful. add some input if you think you have an answer for me . Again probably not the best idea but whats done is done and i cant unsmoke it. lol I would also like to add that at this point in time the rust is completely caked with resin and isnt even visible anymore, would it still be a problem even if i didnt scrape the resin off?
