I smoke it everyday. I have taken breaks for a few months here and there and I did feel a lot better when I didn’t smoke as far as immune system strength. It basically suppresses the immune system some, maybe 5% or so as an estimate if you do it daily. If you do it once in awhile it basically won’t do very much in my opinion. You could have a reaction to it though and thats the main thing to worry about in my opinion. It is a dried item like nuts and so it does contain some molds.
