Santa Rosa detectives were surfing Craigslist one day when they came across a "for sale" posting that caught their attention.
Someone was offering top-shelf marijuana — described as "crystal-laden" and "very distinctly scented" — for $2,700 a pound.
The post came under a banner citing Prop. 215, the voter-approved initiative allowing Californians with a doctor's recommendation to possess and use pot.
"If you're looking for the best, don't waste your time on cheaper meds," read the ad, which was accompanied by a picture of the greenish weed and a phone number.
Undercover officers didn't hesitate to call the number. They set up a purchase April 11 in the Santa Rosa Avenue Target store parking lot, where they arrested Krish Singh, 43, of Rohnert Park.
Despite his insistence that the weed in his orange Camaro was intended for qualified patients, Singh was charged with felony possession for sale and faces prison if convicted at his Aug. 31 trial.
Singh is believed to be just one of hundreds of people who are selling marijuana on Craigslist right next to ads hawking cars, apartment rentals and kitchen appliances.
A quick search of the website Monday showed people selling strains like Presidential Kush and Sour Diesel in quantities ranging from grams to multiple pounds. Postings for hashish are plentiful and there is no shortage of live plants available.
Others were selling medical marijuana cards or looking to buy pot.
Many of the postings specify that the weed will be sold only to patients with doctors' recommendations and then only to members of recognized collectives.
