While THC is not allowed here in Europe (in most countries), we do have "weed" with CBD only
Maybe it's not that potent as THC/CBD combo but for sure it works. We do have vaporizers also, since 2011 we are promoting CBD vaporization, cbd oils and healthy lifestyle in general. I think you have here very interesting project and you will succeed for sure. I wish you all the best! VapeFully
