Smoking anything in your grow room is
not good for your plants. As people have said previously it clogs up the stomata on the leaves.
let me elaborate for those who dont know, the Stomata on the bottoms of plant's leaves are the small pores that alow the leaves to absorb moisture and Co2, without
airborn moisture the leaves dry out, and without CO2 the plant dies...... smoking clogs up the stomata by introducing carbon monoxide(CO) to them, nothing lives off of carbon monoxide.... plants need carbon dioxide(CO2) to survive.

the stomata are highlighted green in this scanning electron microscope picture.
to smoke a small amount, once in a while wont harm them, but smoking every time your around them will. just as a precaution if you do smoke around them spray teh bottoms of the leaves with clean room temperature water to wash away the carbon monoxide (CO)
I have read that smoking tobacco can infect your plants with tobacco mosaic virus - probably BS though.
smoking around the plants will not give them TMV, but using pesticides or fertalizers with nicotine in them will. tobbacco is a known repellant for spider mites, this is why some people feed it to their plants and end up giving them TMV.
