Does Tobacco smoke harm the plants?

I like to kill bugs with my cigarette smoke.. but lately I havent had any bug problems.. Maybe they're all scared..

yeah, it sounds reasonable, but you still need to consider that plants are not humans. With so many variables the comparison is difficult to make (at least with my level of knowledge). I agree with the statement that the effects would be more debilitating over time, but only because continued exposure would increase the levels of carbon monoxide and residual build up that already occur and not because of a correlation between plants and people. Either way, even if a correlation does exist a plant that only lives for 3 to 4 months is going to suffer from exposure to some degree, and thats that. If it can totally kill a plant within a given time frame then it is obviously causing some sort of damage from the very start. Whether or not you take an effort to minimize exposure or even think it would be necessary is totally up to you. I read that you can actually wipe the leaves if it really concerns you. Might be worthwhile if you smoke around your plants and want to avoid any negative consequences. Im really trying to avoid giving out simple opinions and assumptions which seem to dominate the knowledge base here at roll it up. I dont know too much, but I feel like my advice is at least credible and not some canonical idea. So take it for what its worth, if im wrong about something let me know.

My plants are doing fine...but I'm not a smoker. OH...wait...

I was under the impression that you just didn't want to touch seeds with hands that may have been around nicotine, but I suspect for a full grown plant, it's not a big deal.

I actually used to spray the top soil and the trunk area of my plant with a solution I made form cigarette tobacco and soap water (had a gnat problem once). I did this for several weeks actually, with no ill-effects that I could see.

I don't really smoke, so it's not a concern of mine, but I don't think it really matters.

You could give your plants stomata cancer! Plus they could get addicted to nicotine. The real problem is your lights gettin smoke on a hps might make it burn too hot over time!

Don't know about tobacco smoke because i don't be blazing the cigz lol but i blaze dank ass chron around my lady's all the time and they don't seem to mind lol

The forest fire we had last year really blew up my plants ! All that carbon dioxide..they loved it !

Did have to hose the ash off...

What if like science could cross a human into a plant to make a plantanoid lol that would be crazy like what if they could cross a human with a weed plant lol just being a stoner lol hahhahahaah!
