If you are interested in marijuana stocks there is one I've made a lot on. It's BLO.CN , they are developing the breathalyzer for marijuana. It closed today at 2.97, but will go down .10 or .15 tomorrow and then back up probably over 3.00. I bought in Friday at 2.79 and sold today at 2.95 giving me a $3000+ profit for the day. I plan to buy in tomorrow when it drops again, probably 20000 shares, which I will sell again near the close if it goes up enough. It has been doing this up down for some time but I only tried this once before and made considerable on it.
