"The passage of recreational marijuana laws in Alaska, Colorado, Oregon and Washington over the past four years may have unlocked the door to eventual federal legalization," Fuller writes. "But a yes vote in California, which has an economy the size of a large industrial country’s, could blow the door open, experts say." Arcview Group, a company that links investors with cannabis companies, projects that if the measure passes in California the market for recreational and medicinal marijuana will grow from $7 billion this year to $22 billion in four years.

A study published in The Journal of Clinical Psychiatry found that marijuana was more addictive than alcohol but less so than tobacco, Fuller writes. Lead author Jesse Cougle, from the psychology department at Florida State University, told Fuller, “The addictiveness of cannabis has been underestimated,” saying the findings “definitely contradicts a lot of opinions on the topic.” The study found among weekly users "a 25 percent risk of dependence for marijuana compared with 16 percent for alcohol and 67 percent for tobacco."
