Got any sources on this? I'm finding it hard to believe smoke from cannabis combustion is anything other than terrible for your lungs.

  This is the report from the National Academy of Science released this year. It's in no way "terrible". http://www8.nationalacademies.org/onpinews/newsitem.aspx?RecordID=24625 http://www8.nationalacademies.org/onpinews/newsitem.aspx?Rec... Regarding the link between marijuana and cancer, the committee found evidence that suggests smoking cannabis does not increase the risk for cancers often associated with tobacco use – such as lung and head and neck cancers. The committee also found limited evidence that cannabis use is associated with one sub-type of testicular cancer and insufficient evidence that cannabis use by a mother or father during pregnancy leads to a greater risk of cancers in the child The evidence reviewed by the committee suggests that smoking cannabis on a regular basis is associated with more frequent chronic bronchitis episodes and worse respiratory symptoms, such as chronic cough and phlegm production, but quitting cannabis smoking is likely to reduce these conditions. The committee stated that it is unclear whether cannabis use is associated with certain respiratory diseases, including chronic obstructive pulmonary disease, asthma, or worsened lung function.
