It’s been a little over a year since singer, activist and marijuana entrepreneur Melissa Etheridge was arrested for cannabis possession by federal agents in North Dakota near the U.S.-Canada border. Her tour bus was stopped and searched shortly after touring in Alberta, and agents discovered a vape pen containing cannabis oil.

Etheridge, who’s become an outspoken advocate for legalization in the years since she started using the plant medicinally after being diagnosed with breast cancer in her 40s, told Marijuana Moment in a new interview that the experience of being busted did not deter her.

Rather, it has motivated her to continue advocating for patients and spreading the word about marijuana’s therapeutic potential.

Later this month, the singer plans to continue that mission, giving a keynote talk on how art and culture can help bring cannabis into the mainstream at the California Cannabis Business Conference in Anaheim. In the interview below, which has been lightly edited for length and clarity, she speaks about what the audience can expect and the role of celebrities in the legalization movement.

Marijuana Moment: Let’s start by talking about your upcoming speech. How exactly can art and culture “mainstream” cannabis?

Melissa Etheridge: I know that I have lived my life in art. I have made my life art, and my art is my life. I write music and I have experience—when I went through my breast cancer experience, and I used cannabis as medicine for the first time, it was inspiring. It made sense to me on so many levels. Artists, we spend a lot of time in our right brain. We get inspiration—which means “in spirt”—from nothing and make something of it. So it’s easy for us to understand plant medicine. Why shouldn’t we be the ones to help bridge that gap?

MM: Inversely, I wonder how using marijuana has influenced your artistic career?

ME: Oh my goodness, well if you hear everything from after my cancer on, you can hear it. The difference in the work, the depth of my soul-searching, the depth of my spiritual journey. It changed my understanding of parenting. To be more balanced in one’s consciousness, to understand that we have a problem-solving consciousness—the left side, and that gets everything done—yet we need a balance of the oneness, the all there is that’s in the right side.

MM: Where do you see the role of celebrities when it comes to advancing marijuana reform?

ME: Celebrities have a funny role in our world, you know? We keep saying, we’re just people, people. And sometimes we’re just people who have done one thing really well for a long time and that’s what you become a “genius” at—that’s all that that is. So all of a sudden, people are interested in that, so you get this currency, this energy, that is celebrity. Then it’s up to each of us.

I went through this with the LGBT community. I proudly came out and said ‘yes!’ and I’ve heard from, and know that I’ve inspired, many, and that makes me just so happy in my life. Yet I’ve made some mistakes, you know? And we’re all just walking through this. Celebrities, if they choose to, can do a lot. My hope is that I can help others look at cannabis as medicine, as an alternative, when the choice that they’re given is a painkiller, an opioid, to say, “Hey, let’s try to put the stigma away and really get into this plant medicine that won’t harm us as much.” I hope my celebrity can help there.

MM: Do you think there’s a greater need for celebrities who are profiting from the marijuana industry to contribute to the movement in terms of grassroots organizing or contributing to national advocacy groups, for example?

ME: I think that’s a natural byproduct of the movement. I think that the majority of people in the cannabis industry understand it is as a social game-changer on so many levels—on justice reform, on racial inequality, it goes deep. This is a movement.

MM: You also run a marijuana business based in California. What has your experience been like since Proposition 64 went into effect?

ME: We all agree that legalization is a good thing. Prop. 64 is full of almost impossible criteria to me, and it’s causing undue financial burdens. No other industry has ever had to meet these regulation requirements—not even the food industry and certainly not the pharmaceutical industry.

MM: The anniversary of your arrest near the border recently passed. I wonder what you make of the progress we’re seeing in Canada, which is set to launch its legal cannabis system next week, compared to the United States.

ME: Oh, Canada. Again, there are parallels with the LGBT movement. I remember Canada went completely federal—we’re doing gay marriage, bam, same-sex marriage, equality. I don’t know what it is, unless it’s just that anybody who would come to Canada to live—because it’s so darn cold—that they really believe in rights for all, this great thing. I think they also jumped on cannabis pretty early and have seen what it can do for communities, what it can do medicinally, what it can do for businesses and that’s what’s going to just kill us. We are missing out on the opportunity to be the international leaders on cannabis. And it’s these beautiful people up in Canada who are doing it so well. It’s like when the Japanese started making better cars than us.

MM: As a longtime activist, what message would you send to our elected official in Congress, where cannabis reform has stalled for decades?

ME: I’d say, I understand the fear. It has been many decades of misinformation telling us that cannabis is evil. I get it. I’ve heard that also. These are different times and it’s possible to think differently about this medicine. This is an answer for you. Really give it a chance.
