It's bollocks like every other term. Reviews, ratings or reputation of the vendor are the terms that count.

this.

I think there is no actual rule or firm line between medical grade or commercial grade cannabis.

Medical grade normally refers to cannabis that is consumed to treat a condition or alleviate symptoms and is generally grown/produced by a registered, known producer. I guess for control purposes.

Many say it has to be organic or certain potency, but I think it just personal opinions.

If you don't know the vendor/grower/producer personally there is a high chance cannabis can be contaminated with anything ranging from pesticides, chemical fertilisers, etc., etc.

To me it is a touchy subject, as it totally depends on personal consciousness.

So, unless, I grow it myself, it is not medical grade to me. A gamble each time I purchase.

More to be grateful and thankful to those vendors in LB who are true to cannabis itself and cannabis culture.

Medical grade ought to mean that every batch has the same, verified, potency like bedrocan for example. But mostly it's just a buzzword to lure buyers in, like any other advertising..
