OAKLAND POT LAB FILLS OVERSIGHT NEED

OAKLAND -- The mere existence of the Steep Hill Lab presents a 
pointed question: How safe is the marijuana provided to hundreds of 
thousands of medical pot users in California?

How safe is the marijuana provided to hundreds of thousands of 
medical pot users in California?

The Oakland laboratory, started in 2008 by two former growers, has 
tested 12,000 pot samples to assure marijuana businesses that their 
product isn't tainted by dangerous toxic molds or pesticides.

Nearly 50 medical marijuana dispensaries and pot-growing networks 
contract with the lab, California's most renowned cannabis testing location.

Tens of thousands of dollars in medical marijuana can be rendered 
useless if samples are found to contain toxins that could trigger 
respiratory infections, sinusitis or worse.

There is no Food and Drug Administration for marijuana. So the 
private lab fills a profitable niche in a trade operating without 
regulatory oversight.

"This is a success story of self-regulation," said Addison DeMoura, 
Steep Hill Lab's co-founder. "We want people to produce cannabis that 
they would give to the dearest person they love."

No state rules in California require medical marijuana be tested. 
While few pot businesses want a rap of toxic weed, no inspection 
regimen ensures they remove tainted products.

Steep Hill Lab says 3 percent of the pot it tests has unsafe mold 
levels under general guidelines for herbal products. Eighty-five 
percent shows traces of mold.

The medical pot community has cause for seeking assurances that the 
marijuana being peddled is free of toxins that can develop during 
growing, drying or packaging.

A 2008 guidebook, "The Marijuana Medical Handbook," warns of 
Aspergillus, a mold that can appear in marijuana and numerous other 
agricultural products. It can be dangerous for seriously ill people, 
such as AIDS and cancer patients using pot to treat nausea or other 
side effects.

"There have been reports of aspergillosis, a lung infection caused by 
inhalation of spores from the Aspergillus fungus," wrote California 
marijuana researchers Dale Gieringer and Ed Rosenthal and Washington 
physician Gregory Carter.

A 1988 study published by the American College of Chest Physicians 
focused on a pot-smoking leukemia patient in Philadelphia whose death 
was hastened by an infection caused by moldy marijuana.

Recently, tests on pot that undercover police officers bought from a 
Los Angeles dispensary revealed an insecticide, bifenthrin, that 
registered 170 times "tolerable" guidelines set by the Environmental 
Protection Agency for human food or animal feed.

"You may have no idea what it's been treated with," said Assistant 
Los Angeles City Attorney Asha Greenberg. Authorities speculated the 
dispensary sold pot smuggled across the border or grown illicitly.

A new medical pot dispensary ordinance in Los Angeles requires 
testing for pesticides or "any other regulated contaminants" for 
foods or drugs.

Dr. Donald Abrams, chief of oncology at San Francisco General 
Hospital and a researcher in state-funded studies on marijuana's 
usefulness for chronic pain, said most medical pot in California is 
safely grown and poses no health risk.

"That whole story of people getting fungal infections from inhaling 
marijuana is a old wives' tale," he said.

But Abrams said Steep Hill may help establish dosing protocols for 
marijuana so that users can know how much they should smoke.

The lab tests potency levels for tetrahydrocannabinol (THC), the 
psychoactive ingredient in marijuana, and for other compounds known 
for pain-reducing effects.

"This is attempting to standardize a botanical product and let the 
buyer understand what they are purchasing in this medicine," Abrams said.

DeMoura, a marketing representative and former pot dispensary 
operator from Stanislaus County, started the lab with David Lampach, 
a former Wall Street equities trader and marijuana cultivator from 
Mendocino County.

Lampach operates a gas chromatography machine that separates 
marijuana compounds for testing and a mass spectrometer that 
identifies ingredients and potency.

"This is the gold standard for measuring active agents," he said.

Debby Goldsberry, co-founder of the Medical Cannabis Safety Council, 
a Bay Area group of pot growers, dispensary operators and 
researchers, said the science of testing marijuana remains limited.

"What Steep Hill has done is push this issue forward," said 
Goldsberry, whose Berkeley Patients Group marijuana dispensary is 
also working on a testing regimen.

As a result of tests from Steep Hill, Harborside Health Center, a 
cannabis club that serves 47,000 medical users at dispensaries in 
Oakland and San Jose, lists THC levels for each pot strain it provides.

"For the first time in the 3,000-year history of human cannabis 
consumption," it proclaims in promotional materials, "patients will 
be provided with a scientific assessment of the safety and potency of 
products prior to ingesting them."

Steep Hill client Andy Rehm, whose Green Pi kitchen in Berkeley bakes 
"Big Bang Brownies" for pot users, once turned away a grower whose 
weed "smelled like butane."

He sent the lab samples when another cultivator dropped off pot for 
the first time. "Addison (DeMoura) called and said, 'Don't use it' " 
- -- it was positive for unsafe mold, Rehm said.

"We're not trying to scare people," said Dr. Janet Weiss, a 
toxicologist who works with the Steep Hill Lab. "We're saying this 
industry should join the rest of the world in what food and drugs are 
required to do. It shouldn't be a buyers beware market."
