Made-in-America marijuana is on a roll. More than half the states have now voted to permit pot for recreational or medical use, most recently Oregon, Alaska, and the District of Columbia. As a result, Americans appear to be buying more domestic marijuana and an interesting consequence is coming into view: weed grown in the United States is increasingly being smuggled into Mexico, instead of the other way around.

"Two or three years ago, a kilo [2.2 pounds] of marijuana was worth $60 to $90," says Nabor, a 24-year-old pot grower in the northwestern Mexican state of Sinaloa. "But now they're paying us $30 to $40 a kilo. It's a big difference. If the US continues to legalize pot, they'll run us into the ground."

Nabor declines to give his surname because his crop is illegal. The interview takes place on a hillside outside Culiacan, Sinaloa, located in Mexico's marijuana heartland. We stand next to a field of knee-high cannabis plants, their serrated leaves quivering in a warm Pacific breeze. The plot is on communal land next to rows of edible nopal cactus.

He kneels and proudly shows me the resinous buds on the short, stocky plants. This strain, called Chronic, is a favorite among growers for its easy cultivation, fast flowering, and mood-lifting high. Nabor, who says he has grown marijuana since he was 14, says the plants do not belong to him.

"My patrón pays me $150 a month, but I have to plant it exactly the way he wants," he says. "He provides the water pump, gasoline, irrigation hoses, fertilizer, everything."

An Army Of Small-Scale Growers

There's an image of Mexican traffickers with shiny pickups, fancy boots, and shapely girlfriends. But Nabor says most people who grow marijuana for the Sinaloa cartel are just campesinos like him.

He drives a motorcycle, and supports a wife and two kids. He says he grows pot to supplement his other work, which consists of collecting firewood and raising cactus. He says everybody plants a little marijuana here.

"This is dangerous work to cultivate it and to sell it. If the army comes, you have to run or they will grab you and take you to jail. Look here, we're only getting $40 a kilo. The day we get $20 a kilo, it will get to the point that we just won't plant marijuana anymore."

The slumping economics of Mexican marijuana was not unexpected.

Two years ago, the "Mexican Institute of Competitiveness," in a study titled If Our Neighbors Legalize, predicted that the drug cartels would see their cannabis profits plummet 22 to 30 percent if the United States continued to decriminalize marijuana.

At one time, virtually all the weed smoked in the States, from Acapulco Gold to Colombian Red, came from south of the border.

Not anymore.

"We're still seeing marijuana. But it's almost all the homegrown stuff here from the States and from Canada. It's just not the compressed marijuana from Mexico that we see," says Lt. David Socha, of the Austin Police Department narcotics section.

A Preference For Grown In America

"American pot smokers prefer domestically grown marijuana to Mexican grown marijuana. We've seen a ton of evidence of this in the last decade or so," says Daniel Vinkovetsky, who writes under the pen name "Danny Danko." He is senior cultivation editor at High Times magazine and author of The Official High Times Field Guide to Marijuana Strains.

US domestic marijuana, some of it cultivated in high-tech greenhouses, is three or four times more expensive than Mexican marijuana. Vinkovetsky says prices for Mexican weed continue to slide because it's so much less potent.

He says American cannabis typically has 10 to 20 percent THC — the ingredient that makes a person high — whereas the THC content of so-called Mexican brickweed is typically 3 to 8 percent.

"Mexican marijuana is considered to be of poor quality generally because it's grown in bulk, outdoors; it's typically dried but not really cured, which is something we do here in the US with connoisseur-quality cannabis," he says. "And it's also bricked up, meaning that it's compressed, for sale and packaging and in order to get it over the border efficiently."

Reversing The Flow

To service the US market, police agencies report some Mexican crime groups grow marijuana in public lands in the West.

And there's a new development.

DEA spokesman Lawrence Payne says that Sinaloa operatives in the US are reportedly buying high-potency American weed in Colorado and smuggling it back into Mexico for sale to high-paying customers.

"It makes sense," Payne says. "We know the cartels are already smuggling cash into Mexico. If you can buy some really high-quality marijuana here, why not smuggle it south, too, and sell it at a premium?"

The big question is whether the loss of market share is actually hurting the violent Mexican drug mafias.

"The Sinaloa cartel has demonstrated in many instances that it can adapt. I think it's in a process of redefinition toward marijuana," says Javier Valdez, a respected journalist and author who writes books on the narcoculture in Sinaloa.

Valdez says he's heard through the grapevine that marijuana planting has dropped 30 percent in the mountains of Sinaloa. But he says the Sinaloa cartel is old school — it sticks to drugs, even as other cartels, such as the Zetas of Tamaulipas state, have branched out into other types of criminal activity.

"I believe that now, because of the changes they're having to make because of marijuana legalization in the US, the cartels are pushing more cocaine, meth, and heroin. They're diversifying," Valdez says.

Back in the hills above Culiacan, Nabor is asked, if prices for marijuana continue declining, what will he do?

"My dream is to get a good job, a regular job," he says, "where I don't have to do such dangerous work; a job that pays me a living wage."

When the interview is over, and the recorder is turned off, and we're about to drive back to the highway, Nabor quietly says he thinks he's done with marijuana. He's considering planting opium poppies, because that's where the market is going.
