I'm going to take this as a medical question since you placed your post here, but another version of this question might be better placed in our cultivation area where someone with hydroponic grow experience can answer it. Are you quite sure it's mold? The mold I've seen more concern about here is the white powdery substance that occurs when weed's not properly dried or cured, where, after harvest, residual moisture and improper storage cause mold spores to thrive, but I'm clueless about cultivation and I know mold can occur on plants before they're harvested, too. I've seen it on bedding plants in our yard.

From a medical standpoint, what you read is true. It's less than ideal for you to inhale mold spores, particularly if you're immunosuppressed. It won't necessarily be a guarantee for problems, but a lot of people have allergic reactions to molds, responding to the irritation with asthma, rashes, itching, breathing and sinus troubles. Even more problematic is that some mold spores can produce mycotoxins, which are basically harmful chemicals. You certainly wouldn't want to inhale mycotoxins into your lungs or set up a situation where you put yourself at risk for a myco-driven infection such as pneumonia to set in.

Therein lies the problem. You wouldn't necessarily get an infection or even an allergic reaction, and your mold on your plants certainly may not be one of the dangerous or toxic ones. But you can't really know whether it's dangerous or nor or predict how you'll react.

So I would be very leery about smoking it, especially if you're immunosuppressed. Check out our cultivation area and see if you can find a place to post a related version of this question for our resident cultivation experts to see.
