Yeah I know but smoking it in the lungs might not have the same effect as drinking it. I wouldn't take it personally cuz I'm not trying to turn blue but I'll make it myself and spray it on my plants. Lol I've read mixed reviews on colloidal silver consumption. Those who take it swear by it. But I've read it can make antibiotics not work for you if you need them. I stayed clear of it after I read that part of it.
