And what are fake drugs doing with blockchain?
I'm not quite certain where your comment is coming from. The product is developed to prevent copy-cats to deliver certain kinds of "drugs" as occurs now in several country's. The blockchain is used to trace the drug during every step of the way and thus deliver a proof of authenticity this way, while the designed product offers an simple method to verify this.
Due to the interoperable nature of blockchain and the possibility to verify your subscriped/purchased "drug", it will make it harder for any type of counterfeit drug to be bought/sold.
