arenaline naturally occurs in stressful situations, tto get more, pump yourslef up, yell, run, go faster, to get less keep yourself calm and relaxed. effects of drugs, know what your doing first, take the right amount...(there are tricks, it varies from drug to drug , pot wait a while, mushies do something you feel safe with (watch tv, family guy) and coke drink water, breath, relax, and dont talk a crapload (makes you sick if you do sometimes, but hard not to) herion, i dunno, i stay away from that shit completerly, pills, uhhhh no real control, dont to too much, if you did then puke... ___ theoretically if one had a big enough adrenal gland, / if an adrenaline enhacing drug, ar even a mutation occured where you could handle more, couldnt one eventually dodge swords, even bullets? (adrenaline slows down time perception, its the only thing we know of that can currently-------- and you COULD take a human adrenaline gland and do it as a drug, (not sure how but ive heard and i am sure you can) although that requires a dead body (fresh) WHICH I DONT RECOMMEND AT ALL --- and would never actually try----( pretty cool idea though, to think about dodging bullets being possible)
