You bring up a good point and one that I have been curious about for a while. It is well documented that burning tobacco leaves releases tar, carbon monoxide and other carcinogens. It is also known that combusting/burning nearly anything from toast to steak can also release carcinogens. So how is it that MJ seems to defy this pattern of combustion creating tar, carbon monoxide, and other carcinogens just like everything else?
I ask both out of curiosity and also because as I get older my knees, and now my hands, have been getting more painful every year. I am not there yet, but I may end up needing something like this somewhere down the line and I want to be fully aware for when I do.
"They" tried for a long time to make safe smoke. There's all sorts of metals and stuff they added to tobacco, even.
Bottom line is they can make it safER but any cellulose that burns creates problems. Including in green stuff.
But green is used differently. Plus, cured differently. And it may suppress tumors a bit. And it's hard to separate it from smoking since many, but not all, green users also smoke tobacco.
But it's nowhere near SAFE in my opinion. Combustion, no matter what, creates problems.
