I have tried numerous cbd oils from numerous companies and I can not tell a big difference. While cbd may relax me it did nothing to improve my breathing. I have also tried inhaling various forms of cbd oils, waxes and what is called “shatter” and I can say with 100% certainty that everything inhaled was VERY irritating to my lungs and I will avoid inhaling anything into my lungs cbd based or not. So please educate yourselves regarding cbd products, their benefits and limitations. I’ve tried them all and can share my experiences using each.
