Do you mean your weed smells or your pipe smells?

I'm assuming your pipe. I used to have that same problem but then I picked this up from a friend.

1. Scrape your pipe out every week or so
2. Tripple layer the Ziplock bags and change these when you scrape your pipe
3. Maybe every month soak your pipe in a cup of rubbling alcohol or boil it in water for 15 minutes. Be careful though because these (especially boiling) will stink up the house so do it late at night or when no one will be around for a couple hours.
4. Keep the Ziplocks in a leather pouch with no holes.

I have been doing that for the past half year or so and my room went from smelling like a resin bowl to scentless.
