Crystal Meth is bad for you

Breaking Bad is a show based around high school teacher Walter White. Walter was a regular chemistry teacher until one day he found out that he had inoperable lung cancer. He then turned to creating crystal meth to make money in order to support his family before he died with his former student Jesse Pinkman. It’s thrilling to watch Walter as he tries to leads the double life of a chemistry teacher with a family and a diseased drug dealer, but is definitely not something you want to try. Crystal Meth is a methamphetamine. The reason people use it is because it releases a large amount of dopamine which creates a prolonged sense of euphoria. This rush damages the dopamine receptors which eventually leads to not being able to feel pleasure at all. Chronic abuse can lead to psychotic behavior, including paranoia, insomnia, anxiety, extreme aggression, delusions and hallucinations, and even death. Other side effects include diarrhea, nausea, excessive sweating, increased blood pressure, body temperature, heart rate, blood sugar levels, bronchodilation, and “meth mouth”. Meth mouth causes teeth to rapidly decay and fall out. The moral of the story is don’t do drugs.

    “I sometimes think I can do crystal meth, but then I think, hmmm, better not.” -Pitch Perfect

    This quote from the recent movie Pitch Perfect while funny is also very true. Crystal Meth and other drugs like cocaine and heroin are extremely dangerous. The surges of dopamine that are released when these drugs are taken cause the body to be unable to feel pleasure (that euphoric feeling) from things that it used to. This causes the brain of people who are addicted to drugs to change, impairing judgement, decision making, learning and memory, and behavior control, even when they don’t have the drug in their system.

    You are right jk1234, “don’t do drugs”. Even if you just want to try a drug like meth once, don’t do it! This article
    shows why and how people become addicted to meth. Your brain becomes dependent on the chemicals that send these pleasurable impulses that your body would otherwise naturally make. Not only will you become addicted, but each time you take the drug you will need more and more to achieve that euphoric feeling because your tolerance to the drug has gone up.

    And as a side note, the 10th grade chemistry teacher at my school said he can also make Meth just like Walter White does!

    Who would’ve known that something a show is based around is bad for you? This reminds me of the effects of cocaine and how there are also bad side effects of it. Some include kidney failure, strokes, heart attacks, arrhythmia and even ulcers! Its scary to think what kind of substances are out there that can harm you. Don’t do Drugs!
