Cannabis Use in Adolescence: Self-Medication for Anxiety
Data from
the author's practice show that many Californians use cannabis to treat
emotional conditions. Government studies obscure this reality and some
reformers seem reluctant to acknowledge it.
By Tom O’Connell, M.D.
In response to TV news footage of able-bodied young men buying cannabis in
Oakland, city officials voted in 2004 to limit the number of dispensaries. The
politicans were exploiting (and re-enforcing) a misconception that
Californ-ia’s medical marijuana law applies only to those with serious physical
illnesses.
Many of my own patients are seemingly able-bodied young men. Their histories
reveal problems that are indeed serious (impaired functionality at school
and/or work, use of addictive drugs) and that are treated effectively with
cannabis.
I began screening Californians seeking a physician’s approval to use cannabis
in November 2001. Although the reference in Proposition 215 to a doctor’s
“recommendation” of cannabis implied that some applicants would be seeking to
use it medicinally for the first time, the applicants I encountered, almost
invariably, had been using it in non-addictive, stable patterns.
Use of cannabis typically preceded —often by years— the onset of whatever
physical symptoms they were citing to justify their use.
These patients were among those identified as criminals and deviants for
decades by government propaganda. The idea that they were criminals who
belonged in jail or addicts requiring “treatment” simply didn’t make sense.
Never in history has such a large collection of admitted illegal drug users
been so willing to present themselves for unbiased examination.
Developing Research Tools
Although basic demographic data could be obtained by questionnaire, I developed
a detailed interview to examine pertinent areas of personal history. Systematic
exploration of prior drug use revealed that nearly all had tried alcohol and
tobacco aggressively about the same time they tried pot. Many had then tried a
variety of other drugs.
My patients’ drug-initiation patterns suggested they had been addressing
similar needs. Herein, I realized, might be a key to defining the “medical” use
of cannabis and perhaps to better understand its appeal as a “recreational”
agent. I adapted my interview accordingly, as I learned more.
The discovery that most were using cannabis to treat insomnia suggested
self-medication of anxiety or depression —so I expanded that portion of the
interview dealing with psychotropic symptoms. Upon learning that many of the
younger males had already been labeled with ADD, I sharpened my focus on school
and family histories.
The finding that a large percentage had been raised by single mothers and that
many biological fathers of intact families were either heavy drinkers or
preoccupied with work suggested a common etiology for the symptoms exhibited in
adolescence.
By June 2002 I had a standardized list of questions on a form that doubled as a
cue sheet and a place to record answers efficiently and inobtrusively.
Study Population
A total of 3,815 patient encounters between mid-November 2001 and December 1,
2004 have been recorded. Of those, 2,799 were evaluated with the structured
interview. An earlier group of 1,016 had been screened with a more traditional
history and physical. Approximately two thirds (1,850) of the 2,799 structured
interviews were first-timers; the rest were ‘renewals’ of patients seen at
least once previously.
The applicants were seen at several different venues in the Bay Area and many
had traveled from other parts of the state— sometimes hundreds of miles
Virtually all of my original patients had been made aware of my availability
through word of mouth spread through the loose network of buyers’ clubs, which
had —over the first five years of Prop 215— become concentrated in the few Bay
Area counties where they were tolerated by local governments. Presumably they
knew that I was pro-cannabis, but not that I looked favorably on its use as a
treatment for depression and anxiety.
This article relies on detailed data from 790 patients and demographic data
from an additional 364 patients.
Age
Only 3.6% (34/937) were older than 60 when first seen.
5.5% were born before 1946.
16.4% born 1946 - 1955
15.4% born 1956 - 1965
28.0% born 1966 - 1975
35.6% born 1976 - 1985
Those who initiated cannabis use in the 1960s are now in
their fifties and sixties. Most have been using cannabis on a regular basis for
decades, others have resumed after periods of abstinence. The sharp cut-off in
the upper age limit of this population is evidence that an illegal mass market
for “marijuana” really didn’t begin until large numbers of vulnerable
adolescents were exposed to it.
Gender
Of 1118 applicants, 236, or 21.1% were female, a 4:1 ratio which has obtained
throughout the three years of the study. The same 4:1 ratio of males to females
seems to apply to all racial groups.
Race/Ethnicity
Applicants were assigned to four rather arbitrary categories on the basis of
race. When there was doubt about which category was most appropriate, they were
asked their preference. The only observed areas of significant racial
differences were in drug initiation rates. Although the rates at which Black
cannabis smokers try illegal drugs other than cannabis are considerably higher
than the those reported in annual national surveys, they are considerably lower
than among White pot smokers— especially for psychedelics, methamphetamine and
heroin (see table at top left, next page).
Patterns of Use
Patients report that in terms of potency (although not variety), the cannabis
found “on the street” in Northern California is comparable to that available in
clubs.
Although the vast majority were experienced, chronic users, their knowledge of
cannabis lore varied widely and seemed mostly to reflect individual differences
in curiosity. Some were very knowledgeable about strains and delivery systems,
others extremely naive. Very few were using edibles on a regular basis— many
had either experienced or heard about the extended cognitive effects that can
follow ingestion of innocuous appearing baked goods, and —although not clear on
the reasons— preferred to avoid them.
Overwhelmingly, the mode of ingestion favored by applicants was smoking.
Knowledge of vaporizers is beginning to spread, thanks to the cannabis clubs
that sell them. Younger patients seem more inclined to use them on a regular
basis. Some older users express resistance —the best vaporizers are expensive
and old habits hard to change. Several complained that taste and aroma were
lacking.
Late afternoon and evening are the favored times to use cannabis. Early morning
use is favored by those with ADD type symptoms and is discussed more fully
under that heading. Almost all patients have fairly consistent schedules for
their use of cannabis; it is generally solitary and private unless trusted friends
are around. Most people did not tempt fate by smoking at or near work.
Consumption, measured in ounces per week, varied from as little as 1/16 to well
over an ounce, with 70% reporting they use between 1/8 and1/4 ounce. People
smoking 1/2 ounce or more were more apt to either grow it themselvesor have
access to a friend who did.
My impression is that the extreme variations in amounts consumed are more a
reflection of different sensitivities to cannabis than to any greater desire to
get “stoned.” In fact, the impression one gets from discussing cognitive
effects in general is that almost all find excessive effects undesirable and
try hard to avoid them (which is the main reason inhalation is favored over
oral ingestion).
Alcohol & Tobacco Use
The most obvious relationship between alcohol, tobacco, and cannabis is that
nearly all those who try cannabis have either tried the others or will soon do
so. That linkage —first noted in the mid-1970s1— was amply confirmed by the
present study: 100% of applicants had tried cannabis by attempting to get
“high,” usually as adolescents (about 30% either failed on their first attempt
or weren’t sure). 99.3% had also tried alcohol by getting drunk (many were also
monumentally sick) and 93.7% had tried tobacco by inhaling at least one
cigarette.
Few are teetotalers, but
nearly all who still drink do so moderately.
Repeat use of both alcohol and tobacco tended to be
aggressive. More than half had binged in high school or as young adults; 35%
had experienced alcohol black-outs; and 12.5% had received DUI citations. Yet
essentially all who have continued to use cannabis on a regular basis
subsequently moderated their alcohol consumption. Few are teetotalers, but
nearly all who still drink do so moderately. Most have reduced alcohol
consumption to 20% of their peak levels —or less.
Cannabis also has enabled patients to reduce tobacco use. Although 68.1% of
cannabis applicants became daily cigarette smokers for a while, over half (53%)
of the smokers have since been able to quit and almost all the rest are trying.
Even inveterate tobacco smokers (those unable to remain abstinent) uniformly
relate their cigarette consumption to both stress and access to cannabis: when
the former is high and the latter is low, they tend to smoke a lot more
tobacco.
I can recall only two applicants who said they enjoyed smoking cigarettes and
had no intention of quitting.
Initiation of Other Drugs
An individual’s first use of a drug is important for the obvious reason that
drugs never tried never become problems. However, mere trial of an agent does
not signal that repeat use will follow or what its pattern might be if it does.
How chronic use of one agent might ultimately affect use of others is largely
ignored by conventional research.
While children as young as nine occasionally initiate drugs, the greatest
incidence is from 12 on.2 Since most people have tried all the drugs they will
ever use by age 25, adolescence and young adulthood are clearly important areas
for any drug policy to focus on. At first glance, the high initiation rates for
other drugs observed in this population (table at top of next page) would seem
to support the hypothesis that cannabis is a “gateway” to use of other drugs.
A more detailed evaluation discloses that relatively few episodes of problem
use or “addiction” ensued. Those whose use became problematic were generally
able to solve their problems without professional help. Discussing those issues
with applicants left a strong impression that continued use of cannabis had
played a significant role in helping them control not only alcohol and tobacco,
but illegal drugs as well.
Their aggressive trials of psyche-delics can be seen as a manifestation of the
same curiosity exhibited for other agents and presumably impelled by the same
symptoms which had led them to try alcohol, tobacco and cannabis in the first
place. The response of many to being questioned about peyote and mescaline was
that they would have tried them had they been able to find them.
The fact that white cannabis users tried psychedelics at more than double the
rate of blacks is startling and remains unexplained. Availability in their
respective communities is probably a factor.
Paternal Influences
In attempting to determine the origin of the symptoms motivating this
population’s aggressive adolescent drug sampling, the most obvious place to
start was family background. A common element was the absence of their
biological fathers from their early lives —either physically, through early
death or divorce, or emotionally, through a variety of other mechanisms listed
below
Paternal Factors Associated With Adolescent Use of Cannabis
The role played by insecurity and low self-esteem during
applicants’ school careers became increasingly transparent. One or more of the
above situations obtained in nearly all patients.
School Careers
Pre-school day care, kindergarten and primary school are the first
opportunities for most children to socialize outside the family. Being
different for any reason — too short, too tall, unfashionable attire, unusual
name, etc.— can quickly become something one is teased about. Intrinsic shyness
and sensitivity to teasing can make the school setting difficult to bear.
Applicants are now asked to rate their experiences in primary, junior high and
high school as “happy,” “unhappy.” or “mixed.” After emotional tone is
registered, they are asked if they were ever “class clowns” or considered
disruptive by their teachers. They are also asked if descriptions of “Attention
Deficit Hyperactivity Disorder” apply to them.
ADHD and ADD are diagnostic labels increasingly applied to school children
exhibiting behaviors that irritate and frustrate their teachers. The concept
that the condition frequently persists throughout life (“Adult ADD”) has been
endorsed by the medical establishment, and increasing numbers of patients are
being treated with Adderall and other long-acting amphetamines.3
Although the behaviors had long been noted among educators and pediatricians, a
unifying diagnosis seems to have originated in the late ‘60s with Paul Wender,
a child psychiatrist at the University of Utah.4, 5 Treatment of affected
children with stimulants, primarily methylphenidate (Ritalin), began in the
1970s and has become both increasingly common. The ADD/ADHD diagnoses are now
codified in the American Psychiatric Association’s Diagnostic and Statistical
Manual of Mental Disorders.
ADD has been associated from the beginning with dyslexia and several other
so-called “learning disorders.” Among my male patients, the diagnosis of ADD
was either made or suggested for some 10-15% while they were in school. Nearly
as many were diagnosed as adults, or the diagnosis was applied informally by
family members or close friends.
The ADD diagnosis is associated in conventional literature with both “substance
abuse” during adolescence and low self-esteem. The ratio of boys to girls
diagnosed with ADD has remained at about 4:1. As the diagnosis is made more
frequently in adults, it has been noted that fathers with ADD are more apt to
have sons with the condition (and vice-versa). This is a pattern one might
expect in a highly competitive, male dominated society.
The idea that “self-esteem” is both important to a child’s early success and
strongly influenced by the biologic father is certainly not new. Single
mothers, low self-esteem, and a proclivity to try multiple drugs in adolescence
have all been reported as common in children diagnosed with ADD.
There is universal
agreement among applicants who have been diagnosed with and/or treated for ADD
that cannabis helps them achieve and retain focus.
The term “attention deficit disorder” is clearly a misnomer. These individuals
are not inattentive; rather, their problem seems to be that they are so aware
of other stimuli around them that they have trouble remaining focused on the
chore/problem at hand. There is universal agreement among applicants who have
been diagnosed with and/or treated for ADD that cannabis helps them achieve and
retain focus. They also are the ones most likely to use cannabis early in the
day.
Cannabis as Palliative
ADD and other psychiatric conditions are defined by the DSM without reference
to the objective external standards which Anatomic and Clinical Pathology
readily provide for ‘somatic’ (physical) diseases.6
Upon closer analysis, modern “mood” and “behavioral” disorders represent
various combinations of symptoms either observed in— or reported by— those said
to be afflicted. The symptoms include chronic insomnia, dysphoria, depression,
anxiety, excessive anger, difficulty in focusing, agoraphobia, and morning
appetite inhibition.
These symptoms abound in the chronic cannabis users I have interviewed. They
had usually been present since adolescence and predated whatever somatic
symptoms the patient could cite —with varying degrees of credibility— as their
reason for seeking an application.
Prop 215, the state initiative that legalized the medical use of marijuana,
refers to “seriously ill patients.” Why would applicants prefer to cite somatic
symptoms instead of emotional ones? Several explanations can be offered:
• Many male adolescents feel that a “macho” image allows for physical injury
and pain, but not for emotional impairment.
• Medical marijuana advocates, in seeking to maximize public support for their
cause, often invoke “the dying.”
• Law-enforcement opponents of medical marijuana, starting with former state
attorney general Dan Lungren, have sought to trivialize mood disorders and
assert that they are not properly treated by cannabis. Former Drug Czar Barry
McCaffrey, in his first public response to California’s new law, ridiculed the
inclusion of chronic insomnia on a list of conditions treatable by cannabis .
• There is general agreement by all but the most doctrinaire opponents of
medical use of cannabis that it effectively palliates a wide variety of
symptoms produced by an even wider variety of named diseases. The most common
symptoms are chronic pain both of neuritic and musculo-skeletal origin.
The effectiveness of cannabis in treating two “functional” disorders, migraine
and asthma — which are classically exacerbated by but not thought to be caused
by emotions— was well established before the Marijuana Tax Act of 1937.
Cannabis also helps control chronic diarrhea produced by Crohn’s Disease,
Ulcerative Colitis, or Irritable Bowel Syndrome. Its effectiveness in
controlling the tenesmus and cramping of the latter condition also suggests a
spasmolytic mechanism is involved.
In a context where most of the somatic conditions were clearly additive in that
the applicants had aleady been using cannabis to manage emotional symptoms, the
expenditure of scarce assets to “confirm” what amounted to a somatic excuse for
their pot use did not seem reasonable; particularly when the underlying
psychotropic reasons for its use were deemed adequate and a detailed history
had shown they fit the “profile.” There is also a relatively small subset in
whom more sporadic and casual use of pot had become far more regular after the
patient developed a new somatic condtion.
The Gateway Hypothesis
Drugs are initiated in sequence. Prior to the late 1960s, alcohol and tobacco
were primary agents tried by adolescents. When researchers began studying the
phenomenon of youthful cannabis initiation they reported that nearly all their
subjects had already tried both alcohol and tobacco— and that many had
subsequently tried several other agents. Their assumption that cannabis was a
“gateway” from legal to illegal drugs became the prevailing explanation.7
The presumption that all drug use is both hedonistic and harmful added
conviction to that interpretation. Data showing that most heroin addicts had
used cannabis before heroin bolstered the gateway theory, and it seems to have
gone unchallenged for 30 years even though it never met a basic theoretical
test of “causality.”
Evidence that cannabis is capable of benignly and effectively palliating the
psychotropic symptom complexes so often encountered in juveniles and young
adults was clearly beyond the scope of any research funded— or even permitted—
by NIDA. That such symptoms tend to persist into mid-life for many who suffer
from them is now endorsed in psychiatric literature and has spurred development
of a host of pharmaceuticals intended to treat them. Yet most of applicants for
whom these pharmaceuticals were prescribed report that cannabis provides more
effective and durable relief.
A little-noticed 2002 paper by Morral et al demonstrated that a theoretical
“common factor” could provide a better explanation than “gateway” for the
initiation patterns observed.8 My data suggest that the common factor is
adolescent angst.
The previously unrecognized role of cannabis as effective self-medication for
symptoms experienced by adolescents also explains why so many adults have
continued to use it despite potential social and legal penalties.
Summary
Proposition 215 encouraged many individuals who had been considered
“recreational” users of cannabis to apply for “medical” status. Interviews
placing their cannabis use in broader context showed that it is frequently an
alternative to the use of alcohol, tobacco, and “harder” drugs.
The federal government, by imposing a Prohibition based on biased, inadequate
studies, is depriving the American people of a safe and effective medicine.
Beyond that concern, the increasing enthusiasm for drug testing and punishing
those who test positive for cannabis wth either criminal or social sanctions is
destructive to the large —but at this writing unknown —number of Americans
treating emotional symptoms with what may be, for them, the best agent
available.
