So now, after talking about sedative, hypnotics, and anxiolytics,
those medications that allow a person to relax, to take a deep breath,
to take away that anxiety, and to talk a little bit slower.
Now, we're going to jump from that to stimulant use disorder.
So what is stimulant use disorder?
It's ongoing use of stimulants resulting in behavioral and/or emotional impairment,
which affects your activities of daily living and can cause distress.
If you recall, on every single one of these substance use disorders,
it is the ongoing use of a substance that has an impact on activities of daily living,
and it is where that substance becomes the primary focus
and the primary relationship in the person's life.
So stimulants, just like anxiolytics, sedatives, hypnotics, they have medicinal purposes.
They are prescribed, but they are also used for recreation.
So when we're thinking about stimulants, there are some stimulants that are natural,
and then there are the others that are synthetics.
When we think of a natural stimulant, cocaine is a natural stimulant coming from the cocoa bean,
and then you have amphetamines and methamphetamines
which are your synthetic amphetamines.
Whether they are natural or whether they are synthetic,
the impact of taking a stimulant is to increase heightened attention and also, increase energy.
So why do people take amphetamines?
Amphetamines can be prescribed for ADHD, ADD,
attention deficit disorder and attention deficit hyperactive disorder, narcolepsy,
someone who is falling asleep in the middle of the day
and can't keep themselves from sleeping, obesity to cut back on appetite.
And even in some cases, for depression to increase the activity level
because as we know, a person who has depression
often has psychomotor retardation or very slow movements,
by giving them a stimulant that increases their energy level.
Now, over-the-counter medications can also produce the same kinds of effects as stimulants.
So we have herbs, we have high-energy drinks,
and so that is the way we try to get the same impact
and the same outcome from over-the-counter usage.
Caffeine for example, will increase a person's energy
and will have a very short acting but mimicking the kind of thing
that you would see with an amphetamine.
