He could have CBD strains at work bout which he can't really talk and he could have made his own CBD strains for himself? Remember, he's not become the legend he is because he doesn't know how to breed and getting CBD into your weed isn't that much of a challenge .So he was PMing people about CBD cuts and telling them it was for medical research yet at the same time PMing others of his current projects?
BTW, a PM is called a PM (Personal Message) because it is a PERSONAL message. Respect that!
