This is the other thing. There is no such thing as 'medical grade' cannabis, there's poorly grown cannabis and well grown cannabis.
Prohibitionists / the bad guys like to try and use as much medical terminology as they can so they can more easily bring in heavy regulation that big pharma is beholden to. Given some pictures I've seen of LP products, some of their stuff is far from 'medical grade'.
Also there's a recent development with Tilray, apparently their 30% stuff tested at ~20 from an independent lab. Good thing we have all these regulations, eh?
