THE EDUCATOR - Winter 2004
Stronger Pot May
Lead to Reefer Madness

Alarmed by reports that marijuana is becoming
more potent than ever and that children are trying it at younger and younger
ages, U.S. officials are changing their drug policies.
Pot is no longer the gentle weed of the 1960s
and may pose a greater threat than cocaine or even heroin because so many
more people use it. So officials at the National Institutes of Health and at
the White House are hoping to shift some of the focus in research and
enforcement from “hard” drugs such as cocaine and heroin to marijuana.
While drug use overall is falling among
children and teens, the officials worry that the children who are trying pot
are doing so at ever-younger ages, when their brains and bodies are
vulnerable to dangerous side effects.
“Most people have been led to believe that
marijuana is a soft drug, not a drug that causes serious problems,” John
Walters, head of the White House Office of National Drug Control Policy,
said in an interview.
“(But) marijuana today is a much more serious
problem than the vast majority of Americans understand. If you told people
that one in five of 12- to I 7-year-olds who ever used marijuana in their
lives need treatment, I don’t think people would remotely understand it.”
JUMP IN POT-RELATED
DETOX
The number of children and teen-agers in
treatment for marijuana dependence and abuse has jumped 142 percent since
1992, the National Centre on Addiction and Substance Abuse at Columbia
University reported in April.
According to the report, children and teens
are three times more likely to be in treatment for marijuana abuse than for
alcohol, and six times likelier to be in treatment for marijuana than for
all other illegal drugs combined.
And it found the age of youths using marijuana is falling. The teens aged 12
to 17 said on average they started trying marijuana at 13-1/2. The same
survey found that adults aged 18 to 25 had first tried it at 16.
For National Institute on Drug Abuse director
Dr. Nora Volkow the final straw was a report her institute published in May
in the Journal of the American Medical Association showing the steady growth
in the potency of cannabis seized in raids.
According to the University of Mississippi’s
Marijuana Potency Project, average levels of THC, the active ingredient in
marijuana, rose steadily from 3.5 percent in 1988 to more than 7 percent in
2003. Volkow said many studies have shown the brain has its own so-called
endogenous
cannabinoids. These molecules are similar in structure to the active
ingredients in marijuana and are involved in a range of activities and
emotions ranging from eye function to pain regulation and anxiety.
GETTING INTO THE
BRAIN
Brain cells have receptors molecular doorways
designed specifically to interact with these cannabinoids.
The cannabinoids in marijuana may use these
ready-made doorways into brain cells and this is why they cause a high and
reduce pain sensations. But Volkow believes the effects may go beyond the
general feeling of well-being that most marijuana users seek.
“I would predict that stronger pot makes the
brain less likely to respond to endogenous cannabinoids,” Volkow said in an
interview. The effects could be especially marked in young brains still
growing and learning how to respond to stimuli, she said.
While the research so far is inconclusive,
Volkow believes that cannabinoids affect the developing brain and that
stronger pot, combined with earlier use, could make children and teens
anxious, unmotivated or perhaps even psychotic.
As an analogy, Volkow said opiate addicts are
more sensitive to pain, as their overuse of drugs have raised the threshold
at which the body responds and their own bodies produce fewer natural
opiates.
NIDA is seeking proposals from researchers who
want to investigate such possibilities for cannabis, she said.
Proponents of legalizing marijuana disagree
with the official line. Krissy Oechslin of the Marijuana Policy Project
disputes the finding that cannabis products are stronger.
“They make it sound like the THC levels in
marijuana were almost nonexistent, but no one would have smoked it then if
that was true,” she said.
“And there’s evidence that the stronger the
THC, the less of it a person smokes. I don’t want to say it’s good for you,
but I’ll say (more potent Marijuana) is less bad for you.”
While Walters stresses that drug abusers are
patients and not criminals, he hopes to crack down more on producers. And he
says, there is a way to go in getting cooperation from local law enforcement
officials. “For many in enforcement, marijuana is still ‘kiddie dope’,”
Walters said.
Walters is quick to stress he does not want to
overreact. “We shouldn’t be victims of reefer madness,” he said, referring
to the 1930s propaganda film “Reefer Madness” that became a 1970s cult
classic for its over-the-top scenes of marijuana turning teens into
homicidal maniacs.
