The vape cartridges gave me a "high" from CBD for the first time. I've had decent oil drops before and they helped with pain and sleep. The vapor delivery must be really concentrated. The pen these cartridges ship with can deliver a thick hit. Too much for me if I turn it way up. But turned down to 3 or less it still give significant vapor. Got me kinda high the first week. Then I was used to it. Don't get me wrong, this isn't like smoking good weed. But a mild pleasant state of mind and a more relaxed body in my experience. My only complaint is that the pen comes with no instructions. You press the button 5x to turn it on. The only reason I know is because a friend told me. Instructions would be nice mfrs
