It states in the article the reason may be because cannabis kills cells (we have heard of the brain cells already, guess it does not discriminate)

If you look carefully at the paper, you will this:
Cancer risk
A number of studies have yielded conflicting evidence regarding the risks of various cancers associated with Cannabis use. A case- cohort study of men in northwestern Africa showed a significantly increased risk of lung cancer among tobacco smokers who also inhaled Cannabis. A large retrospective cohort study from the United States found that Cannabis use was not associated with tobacco-related cancers and a number of other common malignancies, but did find that among nonsmokers of tobacco, ever having used Cannabis was associated with an increased risk of prostate cancer.[5] A population-based case-control study of the association between Cannabis use and the risk of lung and aerodigestive tract cancers in Los Angeles found no positive associations with any cancer type (oral, pharyngeal, laryngeal, lung, or esophagus) when adjusting for several confounders including cigarette smoking.[6] A comprehensive Health Canada monograph on Marihuana (Marijuana, Cannabis): Information for Health Care Professionals concludes that while there are many cellular and molecular studies that provide strong evidence that inhaled marijuana is carcinogenic, the epidemiologic evidence of a link between marijuana use and cancer is still inconclusive.

It's not quite as simple as you state, I think.
