I participated in a block exchange, two of the blocks I received just
reeked of cigarette smoke. It was so bad I could smell it in the driveway as I walked to the mailbox. Didn't even bother taking them in the house. I laid the blocks on my front patio, sprinkled baking soda over them, and let them sit for a few hours. Shook the baking soda off, the blocks have no smell at all now.
