Hmm.. I had odd smells with bamboo; not so much with hemp. I boiled it 3 times 15 minutes each. It has a slight earthy taste, but it quickly dissipates. I can't say it disappears completely. Also some flavors don't mix well at all with certain materials (Like bamboo and peppermint/menthol). Certainly no stinking at all with the brand that I'm using (BJ43 recommended it and it's the best I've used so far)
This has no odor to me at all. I mean, I smoked for 20+ years so my nose isn't what it once was... seriously not a bad odor that I can detect, and that's before boiling. I still have 20 meters of it
