I don’t know if I’m familiar with drugs apart of medicinal
types. In this season I consume a lot of antihistamines because I have allergies like to flowers, dust and other, I know which one to consume because some of them makes me sleepy so I can't take one of them at the morning, so I take that kind in the afternoon or night. Other drug that I'm familiar in is cocaine because at school you have to learn in biology what this drug does to your brain: briefly explained is this drugs blocks the capacity of neurons to absorbs the dopamine, so this neurotransmitter stays in the "space" making us feel in some ways, the result is the brain gets addicted to those feelings.
Drugs are not always bad; an example is medicine they are drugs but legal, so people tend not to consider them drugs they have the concept of drugs to something harmful. Like I say, medicinal drug are good because they help us to get better, not to feel pain, to prevent some illness. Obviously, some people take medicinal drugs in excess and they get high up; cough syrup is an example because some of them has codeine (opiate) in small portions. Even I did this, maybe not similar but my sister is diagnosed with ADD, she says she is not but it is another story, so she have to take some pills to control that (if I'm not wrong it has some portions of amphetamine very tiny), after a while she refused to them because she felt drugged all the time. She has some spills left so I remember I took one because I had an exam at school, and yes I felt drug but not in a bad way? I just were more focused in just one thing.
Drugs has different effects on the user because they are all different; some makes you energized, sleepy, other even makes you feel depressed. All of this depends on what type of drug are you taking because they are plenty of them. And because all of this you can get addiction to drugs; your body (brain) gets addicted to those feelings and thinks that you can't live without them. So you do stupid thing to have those feelings: some people sells all of their stuff to get the drug, other are capable of killing people for drugs or even they kill themselves because they feel so bad without them. Even when you realize that drugs are bad, you can't left them so easily. All thank to the withdrawal symptoms, the common one is the pain that you feel in all of your body that you can't even bare, also the vomits and stuff because your body is detoxifying itself.
Personally, I don't know no one addicted to drugs so I can't say a personal experience.
In chemistry (like the other careers) you can learn how to do them, so you cant be addicted to them because you can do "bad" things with your knowledge. Also, people thinks you are doing bad to the community with the medicine you can do, even if you are doing the opposite, all because the disinformation that people have.
