i'm talking about in teenagers or young adults...why does it change them and make them act very different?

For several reasons.  One, taking drugs alters your perceptions.  A person who takes drugs is profoundly altering their world-view.  They are "learning/experiencing" things that others don't and it alters them.\n\nSecond, many people take drugs as a form of self-medication.  Ex.  They are emotionally hurting over something and take drugs to feel better; or it is a cry for help.\n\nRegardless, taking recreational drugs can potentially harmful.  Before ingesting substances that could harm you, you should research exactly what it will do for you.\n\nI work as an ER nurse and have seen the dangers of drug abuse.  Marijuana is pretty much harmless, but things like crystal meth are insane.  I wish people could see what "tweakers" look like when they wig out.  I wish they could see the PET scans of tweakers brains... the ones where the brains look like swiss cheese.

A process that people undergo that causes a change in their behavior.

Didn't become that way overnight. Slowly we became bigger, faster, more mobile....our grandparents, their grandparents were different. Big cities, fast pace, fast food, life became a fight. Fight for the better job, the bigger salary, the nicest car, the fanciest house. Toes get stepped on to get to the top, people become less sensitive to the feelings of others. Our kids see it, their kids will probably see it more... off my soapbox, done now. Have a wonderful day, good question by the way.

While I don't subscribe to any of your religious views, teens are very susceptible to influence; from friends, from advertising, and from people that can convince them they have a "better way".  They're at an age where they feel they can & should decide things for themselves, but usually haven't acquired enough experience or wisdom to see that they are making a bad, sometimes even dangerous, decision.

Sometimes it's forced on by parents. All of my friends are 16-17 and, depending on how they're parents treat them, they act either younger or older. For example, I have a friend whose mother died when she was little and this girl knows how to take care of herself since she's been taking care of her dad for a few years. Another friend, though, is a little spoiled brat because she asks for everything and gets it plus more. Or it could be the bad media that shows the blondes in the tight skirts that little kids are exposed to and that's how they think they should act. Well, probably a little bit of both factors and more.

Because people view teenagers as these younger "know-it-alls" who have never lived life and have no idea what it's like to live. They don't understand that times have changed and so have teenagers. They also don't understand that everyone is different, and have gone through different things.

When some people dont understand something, they assume that its "bad" or when something is different to what they do or they expect should be done.  Unfortunatly the older some people get, the more they act this way.  It also may be that they hear a few hip hop songs and find them offensive (eg.eminem) so they think that all people that like hip hop or dress that way are thugs, gangsta's etc...  Its not true and not fair, but people will always be down on somthing in this world and always judge others.  The best thing u can do is to be yourself and for your boys to be themselves.  \n\nPeople like that need to learn that clothes dont make the person, its whats inside that counts and they shouldnt be down on them for following something they believe in and love.  Thats what being a teen and young adult is all about, finding out who you are.  And wouldnt the world be a boring place if we were all the same!

It's like changing your clothes or your hair.  Most people do that all the time.

child sexual abuse,mental,and emotional abuse because these can lead to killing and suicide.They are severely messed up because of someone else and its hard to change them back to innocence, so they become dangerous adults......

May be that some people have a bit of differences and therefore tend to get nervous and out of control!?

I've known stubborn set-in-their-ways people who were 7-years old.  I've known enthusiastic, open-minded, ready to learn and take on new challenges people in their 90s.  My guess is that people are who they are and the years just pile on after that, and it's who they are deep down that will see them open to change or not.\n\nBut my opinion isn't written in stone.  I'm open to changing it.\n\n;)

Today's youth don't have a monopoly on confusion, but at least they have the excuse of lack of experience, where older folks just seem to wallow in confusion (perhaps for attention lol).\n\nThe youth of today will figure things out, and for the most part seem to have a pretty good grasp on things.

I think that it is a combination of both things. Some people just are attention freaks and have to have attention (this is probably because they didn't get enough attention from their parents as small kids). Other people might seriously have some disability or whatnot.\n\nWhatever it is, though, it's pretty annoying to be around these kind of people.

1)Suicidal side effects from antidepressants for some reason affect teens more than any other age group.\n\n2)Many teenagers don't have nearly as much control over their lives as they would like, because of parents, school, boring jobs, etc., so they think of killing theirselves as a way to show everyone that they control their own lives, even in death.\n\n3)Many teens in our society today are neglected in their homes (usually because of 2 parents working or a single parent working 2 jobs) and don't have any true friends at school, so they think that committing suicide, whether successful or failed, is the only way they can get people to pay them any attention.\n\n4)Lastly, hormones fluctuate more drastically in teens than in any other age group, which combined with bad home life and/or certain antidepressants, can force some teens to make irrational and abnormal decisions, including suicide.

There are many ideas to consider in answering this question.  First of all, teens go through incredible chemical changes every minute of every day.  An increase in testosterone (a male hormone) has shown to increase aggressiveness.  Even girls have fluctuating testosterone levels.\n\nAlso, fighting can be considered a cry for attention.  This does not necessarily mean attention from adults.  Peer pressure is a huge issue for teens.  Fighting might be viewed as a way to gain peer acceptance.\n\nDrug abuse may also play a part.  When a teen is high on any particular drug, the teen is noticeably more aggressive than normal.\n\nTeens also lack the social skills to handle differences.  In time, teens learn the appropriate ways to deal with differences of opinions by observing adults interacting.  This is why it is imperative that adults always model appropriate skills around impressionable young adults.

Everyone changes throughout their entire life.  Sometimes it is subtle and sometimes it's dramatic. People don't often notice when it's them.  Just live your life being true to what you believe and surround yourself with positive people.  You will attract the kind of friends who can tell the difference between the truth and a rumor.

It used to be neighborhoods had people that were home all day. Kids had a bit more freedom because no matter where you were someones mom probably saw you. \nPeople now are much more concerned about what they own and how they will get it, we think we have more needs and are always trying to keep up with the standard we see in the media. We are a society of image rather than relationships. We preach tolerance and we judge appearances.\nWe move too fast and seem to think treating each other in insulting ways in comedic. \nPeople demand respect but seldom give it. We judge fast and forgive slowly.
