I bought the Joye 510 for my husband because, even though he was smoking outside, the smoke residue on his clothing was causing respiratory problems for me and our two year old son. At first his use of the Joye 510 seemed fine. But in the past few days, it seems to be producing as much or more smoke than a regular cigarette. His hair and clothing have a strong tobacco odor on them as much or more than a regular cigarette when he comes back into the house. Even my husband admitted that when he smelled his shirt, it had a strong cigarette odor that was very unpleasant. Any ideas of what could be going wrong, and how to fix it?
