In response to this study, critics of smoked marijuana were quick to point out that while THC does have some medicinal benefits, smoked marijuana is a poor delivery mechanism. Citing evidence that marijuana smoke is harmful, Dr. David Murray, then chief scientist at the Office of National Drug Control Policy, noted that “People who smoke marijuana are subject to bacterial infections in the lungs…Is this really what a physician who is treating someone with a compromised immune system wants to prescribe?”209
Dr. Murray also said that the findings are "not particularly persuasive" because of the small number of subjects and the possibility that subjects knew they were smoking marijuana and had an increased expectation of efficacy. He expressed the
government's support for pain relief for HIV-affected individuals and said that while "We're very much supportive of any effort to ameliorate the suffering of AIDs patients, the delivery mechanism for THC should be pills, and not smoked marijuana, which can
cause lung damage and deliver varying dosages of THC.”210"

It would be much better on your lungs.
"Smoking three cannabis joints will cause you to inhale the same amount of toxic chemicals as a whole pack of cigarettes according to researchers from the French National Consumers’ Institute. Cannabis smoke contains seven times more tar and carbon monoxide than cigarette smoke. Someone smoking a joint of cannabis resin rolled with tobacco will inhale twice the amount of benzene and three times as much toluene as if they were smoking a regular cigarette.72

Smoked marijuana has also been associated with an increased risk of the same respiratory symptoms as tobacco, including coughing, phlegm production, chronic bronchitis, shortness of breath and wheezing. Because cannabis plants are contaminated with a range of fungal spores, smoking marijuana may also increase the risk of respiratory exposure by infectious organisms
(i.e., molds and fungi).204
Marijuana takes the risks of tobacco and raises them. Marijuana smoke contains more than 400 chemicals and increases the risk of serious health consequences, including lung damage.205

I know that you love your dope like Chuck loves his sodomy, so my attempt at reasoning with you will obviously fall upon deaf ears.
Hopefully this information will help people that haven't been fooled into believing that marijuana is a harmless drug.
