A large proportion of the population consumes psychoactive substances.
On the other hand a much smaller proportion has substance abuse
problems. These occur when the use of drugs becomes harmful to the
user and/or those around them. For example many people drink alcohol
but only so many are alcoholics: their drug use becomes
Addiction is often confused with substance abuse but is actually only
a symptom of it. It consists in compulsive drug use. The brain’s
reward pathway is hijacked by drugs meaning that repetitive use can
make it extremely hard for the user to resist the temptation to use,
even in situations when it would be harmful, which leads to
It is not related to personality or maturity, anyone can fall into
addiction. It is quite hard to notice in oneself and that’s why the
more people are informed about it the higher chance they may be able
to detect it in friends and family and help them.
It’s important that the myth of instant addiction be debunked. It is
emerging that addiction is not so much related to the actual chemicals
being consumed but rather to environment: both mental and physical.
Studies have shown that even though the morphine that patients receive
in hospital is much stronger than that on the streets, it doesn’t seem
to cause addiction.
Unhealthy environments and bad habits can both lead to substance abuse.
This can be anywhere from a warzone (soldiers in Vietnam used a lot of
heroin) to tough estates or simply loneliness.
Be careful of your drug habits. If you notice you can’t stop taking
drugs even though they are having a very negative impact on your life
(e.g. missing work to get high) or if you start taking drugs too often,
to forget things that make you unhappy, just to pass the time or simply
can’t stop, you may have a problem. Don’t rely on drugs to get you over
a bad day, this is how it becomes your coping mechanism and you
experience cravings and withdrawal symptoms making it very hard to
limit or stop your drug use.
The graph below is an attempt at measuring how harmful a drug is. The
vertical axis is a scale of the dependence potential of a drug from 1
to 10, with 1 being the least. The horizontal axis measure the ratio
of active dose (amount to get high) on lethal dose (amount that will
kill you). In effect, the closer that number is to one the closer the
active dose is to the lethal one meaning it is easier to overdose.
Cannabis in light apple green, on the far left, has a very low active
to lethal ratio meaning it is very safe in that respect but does still
have a relatively high dependence ratio of 4.3.
