1. People like nicotine
Nicotine acts on
nicotinic cholinergic
receptors, triggering
the release of
dopamine, producing
rewarding psychoactive
effects.

Why do people use nicotine? Mood control
In humans, nicotine from tobacco induces
stimulation and pleasure, and reduces
stress and anxiety.
Smokers come to use nicotine to modulate
their level of arousal and for mood control
in daily life.

Why do people use nicotine? Cognitive enhancement
Cognitive improvement is one of the
best-established therapeutic effects of
nicotinic stimulation.
Nicotine improves performance on
attentionally and cognitively demanding
vigilance tasks and response inhibition
performance, suggesting that nicotine
may act to optimize attention/response
mechanisms as well as enhancing
working memory in humans.

Why do people use nicotine? Regulation: Attention deficit disorder
Non-smoking young adults with
ADHD-C showed improvements in
cognitive performance following
nicotine administration in several
domains that are central to ADHD.

Why do people use nicotine? Regulation: Psychosis
…nicotine may represent a
therapeutic strategy for the
treatment of schizophrenia, and a
physiological basis for the
tendency of patients with
schizophrenia to self-medicate by
smoking

Also, Parkinson’s, dementia, weight control, athletic performance…. A significant literature
What if nicotine has
functional benefits and
hedonistic appeal for
some people?
2. The disappearing deterrent
Harm is the currency of tobacco control
Smoking related harms are the most important deterrent to nicotine use
But harms are associated with the delivery system, not the drug
“People smoke for the nicotine but die
from the tar”.
Professor Michael Russell 1932-2009

smoking. BMJ 1976;1:1430–3

Main justification for tobacco control policies is to address harm
What happens to the
deterrent if there is
minimal harm associated
with nicotine use?
3. Is nicotine addictive?
Definitions of “Addiction”
Addiction is marked by a change in behavior caused
by the biochemical changes in the brain after
continued substance abuse. Substance use becomes
the main priority of the addict, regardless of the harm
they may cause to themselves or others.
Addiction Center
A compulsive, chronic, physiological or
psychological need for a habit-forming substance,
behavior, or activity having harmful physical,
psychological, or social effects
Meriam Webster Dictionary
Addiction is a complex condition, a brain disease
that is manifested by compulsive substance use
despite harmful consequence. People with
addiction (severe substance use disorder) have an
intense focus on using a certain substance(s),
such as alcohol or drugs, to the point that it takes
over their life.
American Psychiatric Association
Addiction is defined as a chronic, relapsing
disorder characterized by compulsive drug
seeking and use despite adverse
consequences.
National Institute on Drug Abuse (NIDA)

Formal addiction ontology: Addiction
A mental disposition towards
repeated episodes of abnormally
high levels of motivation to
engage in a behaviour, acquired
as a result of engaging in the
behaviour, where the behaviour
results in risk or occurrence of
serious net harm.
Formal addiction ontology: Addiction
This entity focuses on abnormal
motivation to engage in a
behaviour and includes serious
net harm as a feature. The
reason is to limit the class to
things that merit a treatment and
public health response.
Formal addiction ontology: Dependence
A bodily disposition which is
realised as impaired functioning
following reduction or
termination of use of a
psychoactive substance..
Stigmatising label
Socially acceptable psychoactive substances
Nicotine as a recreational drug
There is no compelling objection to the
recreational and even addictive use of
nicotine provided it is not shown to be
physically, psychologically, or socially
harmful to the user or to others.
The Lancet, 1991
Professor Michael Russell 1932-2009
Russell, M. A. H. (1991). Nicotine use after the year 2000. The Lancet,
337(8751), 1191–1192.
When delivered with
minimal harm, should
nicotine just be regarded
as a socially acceptable
recreational stimulant?
4. Adolescents and nicotine
Youth vaping – United States
Youth vaping – two distinct behaviours
Frequent vaping
Mostly experimental,
or frivolous use
More committed use
Youth vaping comes in
two forms: frivolous
experimentation and
displacement of smoking
Nicotine: only for former smokers?
“Vaping is very unlikely to be risk-free.
So we strongly discourage anyone who
has never smoked from taking up vaping
or smoking.”
“ENDS are not risk free. And they
contain nicotine. So, any use of e-
cigarettes by a kid is bad for public
health.”
Ann McNeill
Professor of Addictions
King’s College London
Mitch Zeller
Former Director
Center for Tobacco Products,
FDA

nicotine have to smoke first?

Should we care less about
youth vaping and focus
more on more serious
risks to young people?
5. New conceptual framing
Long term alternatives to tobacco / smoking
It is not so much the efficacy of new
nicotine delivery systems as temporary
aids to cessation…
Professor Michael Russell 1932-2009
Russell, M. A. H. (1991). The future of nicotine replacement. British
Journal of Addiction, 86(5), 653–658.
...but their potential as long-term
alternatives to tobacco that makes the
virtual elimination of tobacco a realistic
future target.

Tobacco harm reduction
2000 - 2030
2
Tobacco control
1960 - 2010
1 How do we stop tobacco use
and fight Big Tobacco?
How do we reduce harms
caused by smoking?
How do we manage nicotine as
a socially acceptable stimulant?
How do we approach
nicotine once we have
reached “smoke-free”
(happening by
generations already)?
6. Who is threatened by nicotine without harm?
The tobacco control establishment is threatened
Three strategies are evident
1. Disinformation about harm
2. Shifting focus to nicotine
3. Non-health objectives
1. Fake news about health impacts
“These products are falsely marketed as
safer and more sustainable options to
deadly cigarettes, misleading consumers,
media and international institutions.”
1. Fake news about health impacts
“…over 40 organizations and professors from all
continents”.
10 November 2021
“These products are falsely marketed as
safer and more sustainable options to
deadly cigarettes, misleading consumers,
media and international institutions.”
1. Fake news about health impacts
ASH Finland is a national public health
organisation and a tobacco policy
expert. We promote to end the use of
tobacco and other nicotine products as
well as intoxicant-free lifestyle.
2. Shifting goals to nicotine

3. Emphasis on non-health objectives
The tobacco control community finds
it…
“…difficult to accept that availability
of snus may have greater impacts in
reducing smoking than the regulations
we have spent a lifetime fighting for.”
Karl Erik Lund
Tobacco control exists to
address harms and fight
industry malpractice?
What when or if there is
little of either?
