no, it is not that safe. If it doesn't get hot, great, but even so, you are inhaling fumes from glue, so to answer your question, absolutly not.

Like Beefer86 said, save up some cash, and at least buy a cheap bong with a metal bowl. It is much safer than hot glue.
Nochowderforyou Reviewed by Nochowderforyou on . Is hot melt glue a safe sealant? I'm making a bong, but my stem is just a tiny bit too small for my bowl. Can I use hot melt glue to seal them together, or will I end up smoking the glue? Is there any thing else I can use? Rating: 5
