I'm concerned about effects of using BHO and I am thinking about switching to CO2 Oil or finding something cleaner. I have read about people using CO2 oil instead of BHO for piece of mind, and even though its less potent, it still gets you high. For me I would prefer piece of mind since nobody really knows the truth about BHO and its possible concerns. Smoking metals, coating my lungs, inhaling butane over time with possible effects on the CNS and brain damage, and just the idea of inhaling butane...this all sounds too risky for me. Sure it could all be BS but nobody knows. There are all these people here on this forum that say "there is no proof it is bad for you, and until there is I will keep using" well there is also no proof it is safe and until its proven somewhat safe I will keep my distance. I know I am not the only one in this boat with this line of thinking. Why do you use CO2 oil? Do you think or find that it is safer to use than other concentrates? Anything to be concerned about with CO2 Oil? *This thread is for me to learn more about CO2 and help my situation, this is not a duplicate thread. If you don't have a comment relevant to the topic please stay out. Just filled up a Gentleman's v2 cartridge with about .25 grams of CO2 oil. It tasted awesome but it went quick. It vaped up in about 10-15 rips. Seems like I should have got more hits... Does CO2 oil burn faster than wax/shatter? A BB size of shatter gives me 3-5 decent rips and .25 would probably give me 100 rips. Why so much less from CO2 oil? Or did I mess up?
