Haku, first of all congratulations that you are laying your cards on the table here inquiring about whether it would be wise to proceed. That in itself shows a good degree of responsibility, which is one of the things you need to trip and be safe.
It is however not all. Haku, at your age your brain is still developing strongly just like your body is undergoing changes. Your brain is readying itself for adulthood, which developmentally will only be reached around 25, and the software of your brain is being written right now, thats why you are in school, learning all sorts of serious life skills and classes. Right now you are surging up to the person you are becoming, and all your efforts should be focussed on becoming the best you can be, and have as much uncomplicated fun as can be had.
Psychedelics don't really fit that, because tripping requires a lot of energy. Your reality will come apart, while it at your age is still being built. Being 14 is a hectic time as you are learning things on high speed and where you question things you shouldnt and dont question things you should. Psychedelics as they are typically used can add significantly to your burden by offering you uniquely intense experiences that can be either very thought provoking or which cause extreme emotions. A very good or very difficult trip can have you in turmoil for weeks. This can affect your grade.
Then there is the added risk. As you are now, not yet psychologically fully developed, you are more vulnerable than in a few years, because you are right now building the personality traits that you in a few years can fall back on. Everyone has risks of crisis. If pushed too hard, some go depressed, others go psychotic, others get a nervous breakdown. Because you are under the strain of puberty and don't have you adult failsafes yet, something as intense as psychedelics is a bigger risk than it would be in a few years. Theres legal risks too, you are not yet as bright at dodging the law or other authorities than you will be in a few years. You might get a record, and for your parents its hell too.
Think about how much less able to deal with things you were at age 10. You were almost clueless compared to now right? Not to offend you but at 18 you are going to look back at 14 and the difference will be just as big as it will be if you now think back to 10. Its going to be a huge difference.
You could argue that teens in the jungle do it too. They do, but its not expected of them to drive a car, hold a demanding job and live in the great stress of western society like is expected of you. If the drug makes them a little funny in the head, or unsteady of hand, or seeing colors a bit different than they should, its less of a problem for them than it will be for you. They will survive, and so will you, but you might not get as good a job and education as you might have gotten otherwise.
Finally, there really is less to gain for you now than there is in just a few years. The older you are, the richer and more complex trips will become, and the greater the reward can be, offset for the risks you take.
You can see where this is going by now
Live life to the max right now. Give it your best shot in school, have safe fun with girls, do zany fun stuff you will remember fondly for the rest of your life, but wait with drugs. Drugs will not go away. When you are an adult, four christmasses from now, theres going to be even more drugs to choose from and better drugs will have been tried and tested. You can use drugs all your life, but the next few years, you only get one shot at them and this is it.
Odds are you might still ignore our warnings, because your impulse control hasnt developed fully yet, but take it to heart: you asked us and most of us were clear that it would be best if you waited a few years.
I wish you all the best Haku, use this site and sites like Erowid in the coming years to educate yourself about the realities of drugs, so you don't end up addicted or in a freakout nightmare.
If you got questions, ask us, most of us here are glad to help.
