Either way there are negative side-effects from weed. Smoke inhalation is one of them if you are engaging in breathing in the smoke from burning leaves. I'm a supporter or smoking weed 100%. I believe it is a wonderful alternative compared to most pharmaceuticals, especially for those with cancer or nerve damage. I just think a lot of pot advocates go off the deep end snd get so slap happy they believe every positive written article or study that is published. And fyi to those that dont know, studies aren't always entirely factual. Statistics can easily be biased. Again, I support the use but I also don't ignore the negative facts.
