Wall St. Journal:  “In what was once a pipe dream, medical-marijuana companies are courting private investors and even planning public stock sales.  In Colorado, a seed supplier is raising $500,000 in a private financing round. In California, hydroponic-equipment supplier GrowOp Technology Ltd. has raised $1 million privately, with plans to launch an initial public offering this fall. Los Angeles-based Medicine Dispensing Systems, a company that has placed 60 medical-marijuana vending machines in 15 states, would also like to complete an IPO by year’s end.”
