Legalizing pot has not spurred use among U.S. teens: study

A rise in marijuana use among U.S. teens over the past 20 years has no significant tie to the legalization of marijuana for medical use in many states, according to a new research paper.

Comparing surveys of marijuana use by adolescents conducted annually by the federal Centers for Disease Control and Prevention, researchers found the probability that a high schooler had used pot in the last 30 days was no more than 0.8 percent higher in legal states compared to states that had not approved medical marijuana.

"Our results are not consistent with the hypothesis that the legalization of medical marijuana caused an increase in the use of marijuana among high school students," D. Mark Anderson of Montana State University, Daniel Rees of the University of Colorado and Benjamin Hansen of the University of Oregon wrote.

Twenty-one states and the District of Columbia have legalized the use of marijuana for medical purposes, while two states, Colorado and Washington, now allow recreational use. Alaska and Oregon are set to vote on legalization for recreational use in November, while supporters of full legalization in the nation’s capital say they have enough signatures to put the measure on the ballot.

Marijuana remains illegal under federal law.

Some opponents of legalization are concerned it will increase use among teens. According to Monitoring the Future, an organization funded by the National Institute on Drug Abuse that has surveyed drug use among teens since 1975, 36 percent of high school seniors surveyed in 2013 said they used pot in the last year, while 6.5 percent said they used it almost every day.

The artwork of Mike Stilkey

Los Angeles native Mike Stilkey has always been attracted to painting and drawing not only on vintage paper, record covers and book pages, but on the books themselves.

Using a mix of ink, colored pencil, paint and lacquer, Stilkey depicts a melancholic and at times a whimsical cast of characters inhabiting ambiguous spaces and narratives of fantasy and fairy tales. A lingering sense of loss and longing hints at emotional depth and draws the viewer into their introspective thrall with a mixture of capricious poetry, wit, and mystery.

His work is reminiscent of Weimar-era German expressionism and his style has been described by some as capturing features of artists ranging from Edward Gorey to Egon Schiele.
His work has been exhibited throughout the United States as well as internationally. (mikestilkey.com)

White House warns climate inaction could cost US billions

Delaying efforts to reduce greenhouse gas emissions could cost the US $150 billion per year, the White House warned Tuesday in a report on the economic consequences of inaction on climate change.

"Although delaying action can reduce costs in the short run, on net, delaying action to limit the effects of climate change is costly," the report said.

"A delay that results in warming of 3 degrees Celsius (5.4 degrees Fahrenheit) above preindustrial levels, instead of 2 degrees, could increase economic damages by approximately 0.9 percent of global output," the report said.

That figure represents approximately $150 billion in terms of the estimated 2014 US GDP.

"These costs are not one-time, but are rather incurred year after year because of the permanent damage caused by increased climate change resulting from the delay," the report said.
