Wait until you are closervto 18 if not 21 to allow your brain to develop especially the emotional regulation area in the front behind your forehead. If you must experiment do something less serrious like cannabis, which can lead to dependancy or tryptamine based psychedelics basically mushrooms as even if you get real LSD-25 it is quite a risky compound as far as tryptamine goes while phenethylamines can be much harder for the body while mescaline is the only natural one being the most difficult to produce and obtain. Definitely avoid coke/crack, meth, heroin & other opiates even opium, benzos like xanax, and most pharmaceuticals as every compound can lead to dependancy.
Also clearing a misconception that no matter how you ingest meth be it smoking, shooting, snorting, plugging, or eating they are all just as adictive as one another. The only difference is what is called bioavailability, which is the percentage of what is administered becomes active when matabolised so a bioavailability of 30% would mean 30 mg of a 100 mg dose would be active where IV injection is the standard for 100% for each compound.
You have your whole life ahead of you. Do not throw it away experimenting with drugs. getting the meth wet and tossing it was smart and I commend you for doing that. You will feel a lot better in a day or so once the meth leftovers are pumped out and you brain chemistry reserves refill with dopamine. Try eating bannanas as they contain the precourser to dopamine... The best thing you can do now is think positive and save the drug use for later in life at least collage.
