Actually not all are scams, I am confident that MDCN may turn out to be a stock worth following. I was recently working in Atholville, New Brunswick where Zenabis is due to open a big facility cultivating medical marihuana. MDCN has a 49% stake in this operation, and at around $1.50 per share, this could be something worth following. Certainly the locals of Atholville are all over this.
One other point with MDCN, the Pumps and Dumps.com website has never listed MDCN as a pump, the same can't be said of MediJane and a whole raft of other marihuana stock frauds.
