NEW YORK: Wall Street seems to be losing its appetite for pot.

Marijuana stocks were high flyers — so to speak — after Colorado and Washington states legalized pot sales and several other states announced they may legalize sales or decriminalize possession. Shares in about 20 marijuana-related companies began soaring, with some gaining more than 500% off 52-week lows.

But marijuana mania continues to fade as investors realize there’s more smoke than fire at many companies, which show “pot-tential” but little actual revenue. CannaVest, which specializes in industrial hemp production, had climbed to $180 a share last month. After dropping 11% to to $61.45 Thursday, it’s lost nearly two-thirds of its market value.
