As the movement to legalize marijuana gains traction, some environmental activists and celebrities are throwing in their support for legalization, while others have simply admitted to using pot at some point in their lives.
Many celebrities and politicians have publicly come forward as either current or reformed pot smokers. There are some, like Paul McCartney, who have reportedly left those days behind them. At the age of 69, McCartney told Rolling Stone that he smoked his share already. "Enough's enough," he said. On the other end of the spectrum are those still rolling, like famous director Oliver Stone. “It can be done legally, safely, healthy,” Stone insisted in a recent Associated Press interview.
Some environmentalists have voiced concerns over a report suggesting indoor marijuana growing may account for one percent of U.S. electricity consumption, with advocates arguing that by legalizing pot, the footprint could be reduced with more outdoor growing.
Take a look at the slideshow below of some environmentalists who have admitted to smoking pot, and share your thoughts on the marijuana debate in the comments below.

Morgan Freeman is a strong, but silent, environmental force. Not only did he narrate the <a href="http://www.nationalgeographic.com/marchofthepenguins/" target="_hplink">Academy Award-winning documentary March of the Penguins</a>, but he also lent his voice to <a href="http://www.ecorazzi.com/2007/10/12/morgan-freeman-and-brad-pitt-narrate-upcoming-pbs-series-e2/" target="_hplink">a PBS series about eco-consciousness</a>, supported the <a href="http://www.msarl.org/" target="_hplink">Mississippi Animal Rescue League</a>, advocates for <a href="http://www.huffingtonpost.com/2010/07/23/morgan-freeman-on-the-imp_n_657721.html" target="_hplink">natural disaster relief</a>, and sat on the <a href="http://grist.org/article/freeman/" target="_hplink">Board of Directors for Earth Biofuel</a> (now defunct).

"I f--ked too many chicks and did too many drugs, and that's the truth," he told the news site. He goes on to note that a smart campaigner would have to put it all out on the table and say "I did it all. I drank the bong water."

As an avid <a href="http://www.politico.com/news/stories/0709/24753.html" target="_hplink">climate change initiative supporter and conservationist</a> (according to Politico), Barbra Streisand knows the importance of the environment.

In an interview with Rolling Stone, <a href="http://barbra-archives.com/bjs_library/70s/rolling_stone.html" target="_hplink">Streisand remembers how she used to loosen up on stage</a> in Vegas: <blockquote>"Anyway, since I get nervous in places like Vegas, it occurred to me to do this funny little routine--actually telling the audience about my hangup. The point was, you shouldn't rely on emotional crutches. It was almost a sermon--no crutches, people; crutches are a no-no. Then at the end, I'd take out a joint and light it. First, just faking it. Then I started lighting live joints, passing them around to the band--you know. It was great--it relieved all my tensions. And I ended up with the greatest supply of grass ever. Other acts up and down the Strip heard about what I was doing --Little Anthony and the Imperials, people like that--and started sending me the best dope in the world. I never ran out. Hm ... I wonder if I should tell that story."</blockquote>

<a href="http://michaelpollan.com/" target="_hplink">Renowned environmentalist and author Michael Pollan</a> may not have the "stoner look", but he readily admits that he used to grow his own pot. In his book "The Botany Of Desire" <a href="http://michaelpollan.com/articles-archive/how-pot-has-grown/" target="_hplink">he makes mention of his marijuana-growing past</a>, and even discusses it in The New York Times Magazine. "A bit of historical perspective, by way of a confession," he begins. "Not only did your correspondent once inhale but, like a great many other gardeners (and nongardeners) of my generation, I also once grew."
