What is FASD?
Fetal Alcohol Spectrum Disorder. It happens when the fetus is exposed to alcohol during pregnancy. It causes problems with the baby's development.
What part of the brain is effected by meth?
The amygdala - the control center for emotion regulation and "flight or fight." It causes inflammation, flooding it with norepinephrine, and shuts down the prefrontal cortex which would calm your system own.
What is the difference between heroin and fentanyl?
Fentanyl is about 50 times stronger than heroin.
Here's how much is takes to overdose:
Nicotine breaks down 2 things in your body called collagen and elastin. What does this do?
Causes permeant wrinkles - sometimes permenantly.
What BAC does vision, judgement, and response time get effected?
.05
What major effect does marijuana have on the brain?
Memory. It locks into receptors int he hippocampus and makes it hard for neurons to talk to each other.
How does meth use effect empathy?
It causes inflammation in the brain. This sets off our immune cells which get overactive and kill the brain matter inside the amygdala, causing loss of empathy.
Both meth and heroin/fentanyl bind to receptors and cause pleasure. Why is one an "upper" and one a "downer?"
Meth and "uppers" trigger chemicals called norepinephrine that cause an adrenaline rush. Opiates and "downers" shut norepinephrine down, causing your breathing to slow, heart rate to slow, and your blood pressure to fall.
How does nicotine effect your blood pressure?
It triggers the adrenal gland, sending signals to spike your heart rate and blood pressure. Your heart and blood vessels work harder and can get damaged.
What does the is the Blood Brain Barrier and how does alcohol effect it?
Cell wall protecting the brain from harmful substances. Causes inflammation and can kill brain cells.
How does marijuana effect decision making?
In teen years, the brain does "synaptic pruning" in the prefrontal cortex. Marijuana slows this down, making it harder for your brain to "streamline" decisions.
How does meth stop us from feeling joy?
When meth causes a flood of dopamine, our brain cells protect itself by locking down and destroying receptors so it can't be effected by dopamine and you can't feel joy anymore.
What distressing GI issues do heroin and fentanyl cause?
Severe constipation. There are opioid receptors in the digestive track that it binds to and freezes.

Heart failure because of blood vessels tightening and your heart having to work harder. Kidney failure because the body overheats and dead cells shut down the kidney's filters.
Why can the heart and lungs fail when you use heroin and fentanyl?
Heroin and fentanyl attack the brain stem which controls all our automatic processes for staying alive - breathing, heart rate, sleep/wake cycles, and more. Heroin/fentanyl binds to the receptors that the chemicals normally go through to control these systems.
How does nicotine clog your arteries?
It destroys the cells that make blood flow smoothly, making things "sticky." Immune cells and fat then build up. This can cause blood clots and stroke.
What serious liver disease does alcohol cause?
Cirrhosis. The liver tissue dies and it becomes scarred - on and on until it fails completely. This can cause body swelling, brain fog, and other problems because the liver isn't filtering toxins.
How does marijuana effect puberty?
Marijuana suppresses the pituitary gland that controls growth, and activates cortisol which manages stress - causing anxiety and development delays.
What causes "meth mouth" and meth sores?
Meth turns off salvia production which protects our teeth from acid. Meth sores happen because too much dopamine can cause hallucinations, like bugs crawling on skin, causing people to pick at their skin.
What does heroin and fentanyl do to the immune system?
Binds to white blood cells and sends chemicals telling them to stop producing, leaving you more vulnerable to disease. It also triggers white blood cells to self-destruct. This makes injection drug use especially dangerous.
True or False: Vapes without nicotine are safe.
False. the heated metal released aerosols - tiny particles with toxic metals that directly damage your lungs.
