I can vouch for White Rhino when it comes to pain relief! It really works wonders, the high levels of cbd and cbn are more than obvious when you're sitting down all comfy, the smell and taste are so strong and lovely, it's hard to think of a better overall strain [for me] The smell of it is such a STRONG pungent smell, cant get over it, but its very crisp, stings the nostrills almost, very earthy musky/skunky and will fill a room within a second before you even burn it! Amazing strain, but becomming rarer in the UK now. Possibly becuase of the strong smell, and the fact alot of grow rooms are being raided based on the smell comming from them. [police are literally walking around the UK sniffing.... and thats apparantly enough to go get a search warrant and ruin someones life for nothing!]
