The worst thing about weed smoking culture (at least here in Germany) is that people tend to only make tips and not use filters, even when they mix with tobacco, which also a lot of people do. I don’t want unfiltered smoke in my lungs and I definitely don’t want unfiltered smoke with tar and nicotine.

It's the reason why I only eat my weed. The harm from smoking, simply burning stuff into my lungs would cancel out any good effects of the weed. But maybe its because I have asthma and allergies, maybe for those that are healthier its slightly less bad.
