Carolyn Petty
Carolyn has over 25 years of Executive Financial and Management experience. She served as member and as mayor of the Hermosa Beach, CA Council from 2013-2017. Partnered with Heidi Swan, Carolyn helped lead the opposition campaign to Measure M which would have overturned the ban on Cannabis dispensaries in Hermosa Beach. It was resoundingly defeated with 72% of the electorate voting NO. She advised and assisted Manhattan Beach residents who opposed Measure MB, which would also have overturned the ban on Cannabis dispensaries in Manhattan Beach. That measure was also resoundingly defeated, with 77% of the electorate voting NO.

​Ms. Petty has served on numerous boards including the Hermosa Beach Education Foundation, the Hermosa Beach Chamber of Commerce, Harbor Interfaith Services and the League of California Cities.

Heidi Anderson-Swan
Heidi is proud to have appeared on the 2022-3 season of Dr. Phil in an episode about Marijuana Legalization. She’s been interviewed by NBC-LA and Fox.com discussing her work to educate the public about the mental health harms of marijuana. Heidi believes it is crucial the public understand the link between THC and mental illness. She is especially passionate about today’s highly concentrated THC and its impact on our homeless crisis. She describes how the normalization of this psychoactive substance follows a similar trajectory to the rise in homelessness, especially in legalized states like Washington, California, Oregon and Colorado.

This touches Heidi deeply because her brother, Kirk, was a homeless drug addict with schizophrenia. Heidi candidly shares that she and her brother each experienced Cannabis Induced Psychosis. When she describes their very personal stories, she also weaves in the latest research. This makes for compellingly personal, and scientifically supported, interviews and presentations.

To teach youth about the short and long-term harms of THC, Heidi and Kirk co-authored A Night In Jail: the first fictional story illustrating the negative mental health consequences of youth marijuana use. It is inspired by Kirk’s true life. This gritty story is a novella, audiobook, film and play.

Much of 2022 was devoted to volunteering with California’s SB 1097, a bill to add mental health to warning labels on THC products. This bill was pulled due to pressure from the industry. Colorado is the only state to provide mental and physical warnings with the purchase of THC concentrates.

Also in 2022, Heidi helped lead a resistance in her own community, Hermosa Beach, against a measure to legalize pot shops. She was honored to be appointed to her city’s Cannabis Advisory Group to make recommendations to the City Council.

Heidi's work has brought her to Washington D.C. to speak with Drug Advisors to Senator Dianne Feinstein and then-Senator Kamala Harris.

She’s been an instructor for Continuing Education for lawyers and fiduciaries and has been the keynote speaker for Alcoholism and Substance Abuse Providers of New York State. She’s presented for numerous mental health, youth and prevention groups including Smart Approaches to Marijuana, Johnny’s Ambassadors and will be presenting for a 3rd year in a row at Stanford’s Teaching Cannabis Awareness and Prevention Conference.

​Heidi is on the Advisory Committee for Johnny’s Ambassadors and Advisory Committee at Every Brain Matters.

by H.A. Swan (Author), K. Anderson (Author)

Inspired by true events. Busted for smoking pot, suburbanite college-bound Danny is incredulous when forced to spend the night in jail. He’s repulsed by his cellmate, a homeless and mentally ill drug addict who keeps him awake all night with his delusional rants. By morning Danny’s world is completely upended. A Night In Jail is a grim page-turner with a staggering ending.

Cathy and her family have lived in Redding, CA since 1987. Their children attended local schools. Both she and her husband of 48 years were business owners and very involved in their children's sports and activities. After losing their son to a drunk driver, Cathy has focused her career on drug prevention and education both for students and adults.

Cathy has turned her extensive desire to educate students as well as adults on the multiple dangers of marijuana. Both the illegal market and holding our leaders accountable for the legal market in our communities.

We all must push our leaders and others to look beyond the promised dollars and smoke screen of marijuana. We must be a voice for our youth to provide them with the opportunities to live drug free.

Top 10 Things a Community Should Consider
1.Marijuana impaired drivers are more likely to kill pedestrians and bicyclists than alcohol-impaired drivers.
Since 2015, drugged driving in the US surpassed drunk driving as the cause of fatalities in motor vehicle crashes. The #1 drug in those crashes is marijuana.

2. Increased crime in neighborhoods

9. The promised windfall of marijuana Taxes never reaches what's promised and the marijuana black market continues to thrive despite legalization.
