Replying to Smoking canibus increases lung function

A study taken over 20 years show an increase in lung capacity in weed smokers even higher than the average person.

here is why canibus is so much better than cigarettes or tabaco.

But Tashkin argues that specific properties of marijuana also matter.  He says that THC has anti-inflammatory and immune suppressing properties, which may prevent lung irritation from developing into chronic obstructive pulmonary disease (COPD), a devastating lung disorder frequently caused by tobacco smoking.

As for cancer, he says, “the THC in marijuana has well-defined anti-tumoral effects that have been shown to inhibit the growth of a variety of cancers in animal models and tissue culture systems, thus counteracting the potentially tumorigenic effects of the procarcinogens in marijuana smoke.”
