I guess this is just more evidence that these domain names are extremely valuable. The word 'drugs' cannot be trademarked, because it is merely descriptive, and so this guy has no worries that the domain will be taken from him.
Enforcement though is key.
I understand that things have been a little different in the Net world, but a domain name with a different extension has nothing to do with the actual business name of a company. This is what I mean by saying a good name is truly invaluable. I remember reading that when he bought it he said he didn't have any specific plans for it, but expected that within a few years some drug company would realize how valuable it was and would pay much much more for it. Nothing can replace that. I wasn't referring to RealNames at all.
