Former NIH Drug Abuse Director Sends Letter to Canada Task Force on Marijuana

To the Canadian Task Force on Marijuana Legalization and Regulation:

By way of introduction, I was the first Director of the National Institute of Health’s National Institute on Drug Abuse (NIDA), the United States’ principal agency devoted to scientific research on drugs of abuse, including marijuana. I am currently the President of the Institute for Behavior and Health, Inc., a non-profit organization devoted to reducing illegal drug use, and Clinical Professor of Psychiatry at Georgetown University School of Medicine. I urge you to not underestimate the significant negative public health impacts of marijuana legalization.

In response to the discussion paper, Toward the Legalization, Regulation and Restriction of Access to Marijuana, I would like to share with you some important information specifically related to the discussion of the gateway theory. Marijuana is in fact a “gateway” drug – but importantly, it is not the only gateway drug. Alcohol and tobacco are also gateway drugs. By this I mean that their use is highly correlated with one another and nearly always precipitates the use of other substances. Recent analysis of data from the US National Household Survey on Drug Use and Health (NSDUH) confirm that among young people aged 12 to 17, using one of these three primary drugs of abuse dramatically increases the likelihood of use of the other two, as well as use of other illicit drugs. Similarly, the decision not to use any of these three drugs is negatively correlated with use of the other two drugs (as well as other illicit drugs). This finding has significance for Canada and the US, as well as any other nation considering adding marijuana as a third legal drug for adults. More use of marijuana means more use of other drugs, including the two currently legal drugs. As such, given that the vast majority of substance use disorders, i.e., addiction, can be traced to initiation of substance use during adolescence, there must be significant focus on prevention.

Marijuana is not a harmless drug as it is often perceived to be today. In the US, marijuana accounts for more substance use disorders than any other drug (other than alcohol). Of the 7.1 million Americans aged 12 and older with substance use disorders related to illicit drugs, nearly 60% are dependent on or abuse marijuana (Center for Behavioral Health Statistics and Quality, 2015). The only drug that causes more substance use disorders than marijuana is alcohol.

Making marijuana more easily accessible and subsequently increasing its use by the public should be of serious concern to the Canadian government and its citizens. Recent research has shown that daily or near-daily marijuana users in the US consume most of the drug, with the poor and less-educated representing a disproportionate number of marijuana users (Davenport & Caulkins, 2016). Protecting the vulnerable populations – from youth to the disadvantaged – must be a national and global priority.

I urge you to support policies and programs that seek to reduce drug use, including marijuana use, and to improve public health. Making marijuana more accessible and its use more acceptable is not in the interest of public health.

Sincerely,

Robert L. DuPont, MD
President
Institute for Behavior and Health, Inc.

Editors Note:  The New York Times opinion series “Room for Debate” asked if marijuana should be legalized in the face of today’s heroin and opioid crisis and if it is a gateway drug. IBH President Robert L. DuPont, MD contributed to the series stating that marijuana use is positively correlated with other drug use; marijuana users consume more legal and illegal drugs than non-users. Rather than legalize drugs, effective prevention is needed. He clearly states that establishing marijuana “as a third legal drug, along with tobacco and alcohol, will increase drug abuse, including the expanding opioid epidemic.”

Stop Pot 2016 is a California focused, non-partisan grassroots campaign started by citizens concerned about the damaging health effects, both physical and mental, of marijuana. We are also concerned about the impact of marijuana on the environment.

One thought on “Drug Abuse Expert says Gateway Theory is Fact”

  1. Dr. Dupont is certainly among the group I described earlier as “top brass” in the fields of neuroscience and drug addiction. Unfortunately it appears much of our country (and Canada) is far more enthusiastic about what’s trendy rather heeding science based warnings of medicine. Part of the problem I suspect is rooted in the natural feeling of invincibility of the youth. Combine that with the pot lobby’s ongoing effort to make marijuana use seem like ‘normal’ behavior, and we have some real problems. Somehow we got this notion there is a ‘free lunch’ with marijuana.

    What many don’t realize is that drug problems left unaddressed will catch up and eventually overwhelm. Many of the entertainment personalities who have endured addiction could do a great service to our country if they went national (without embarrassment) and explained how they got lured into drugs. Then they could explain how their habits progressed, how they often experimented with other drugs, and how they eventually began flirting with life threatening disaster.

    The irony of course is that after the initial experimentation phase, the euphoric response wears off and drug use becomes a driving force just feel normal. The addict does not like drugs (and they are no longer ‘cool and trendy’!); instead he or she is trapped in a vicious, downward spiral because the brain ceases its ability to provide a healthy neurotransmitter balance that normally makes individuals feel good and alive.

    The youth will listen to them.
