Are charcoal filter tubes safe?
Bought some cigarette filters that are "carbon active" (to roll joints with) and the people at the store said it helps better to stop various toxins from passing through. Does it really? Are there even worse effects?

Nothing is "safe" for smoking, who really knows. It could just be a selling point or they might actually reduce toxins by a conciderable margin. Just be aware that some forms of carbon are lipophilic and may filter out THC. No research is going to accurately prove or disprove how much safer those filters really are, especially since anyone willing to participate in such a study probably has smoked for quite a while.
