What are some problems that scientists have when they investigate the effects of drugs on the brain?

They can't actually see one working. The effects ae difficult to see in action in terms of how the brain physically responds.

I dont advise it although the drug interaction is just moderate. Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and impairment of judgment, thinking, and psychomotor skills.

This question needs to be more defined. Every drug affects every person differently. They are used for recreation, they are used to cure, they are used to help in life. There are effects would be way to numerous to try to list here.

This is a very useful and infomative site on the general effects of catagorized drugs and individual drugs and the effect on the human body/health.\n\nhttp://teacher.scholastic.com/scholasticnews/indepth/headsup/facts/index.asp?article=medications\n\nHope this helps. I believe it has all the info you are looking for.

It depends on the chemical, some chemical can change leaves in the brain that can cause or mimic depression.

*Shaking my shaggy skull* Noperz, smoking pot makes you no smarter or dumber than you started out to be in the first place.\n\nBut that said I must add a few things...\n\nContrary to the popular myth that smoking marijuana kills brain cells there is mounting evidence that is not only false, but the effects of THC could have the opposite effect.\n\nCannabinoids promote embryonic and adult hippocampus neurogenesis and produce anxiolytic- and antidepressant-like effects. http://66.218.69.11/search/cache?p=neurogenesis+and+marijuana&ei=UTF-8&rls=org.mozilla%3Aen-US%3Aofficial&fr=moz3&u=www.jci.org/cgi/reprint/115/11/3104.pdf&w=neurogenesis+marijuana&d=GGiVrm1aMbo9&icp=1&.intl=us\n\nPrevious research had suggested that neurogenesis happens only in select locations in the brain, such as the hippocampus, a region involved in learning and memory. Some studies have shown that this process is inhibited by most illicit drugs, such as cocaine, heroin, and methamphetamine. However, says Xia Zhang of the University of Saskatchewan in Saskatoon, marijuana's effect on neurogenesis has not been clear.\n\nHe and his colleagues started investigating this mystery by searching cell surfaces in live, cultured slices of rat hippocampus for receptors that respond to marijuana and a few other similar drugs, called cannabinoids. They reasoned that if marijuana affected neurogenesis in the hippocampus, then cells in that area must have a way to recognize the drug. Sure enough, 95 percent of hippocampus cells responsible for neurogenesis showed evidence of cannabinoid 1 ( CB1 ) receptors, one of two receptors that respond to cannabinoid drugs. http://www.mapinc.org/drugnews/v05/n1624/a06.html\n\nThe current study focused on a particular formulation of synthetic cannabinoid known as HU210 -- a compound which Zhang described as the most powerful cannabinoid in the world.\n\nThe authors explored both the short-term and long-term effects of exposure to HU210 in rats.\n\nTo measure the drug's short-term response, they gave adult rats a single injection of HU210. To study the same drug's effect over the longer term, the researchers gave a separate group of adult rats twice-daily injections of the cannabinoid over a two-week period.\n\nAutopsies revealed that by the end of the 10-day HU210 treatment regimen, new neurons had been generated and integrated into the circuitry of the hippocampus region of the rat's brains. This process, known as neurogenesis, was still in evidence a full month after treatment had been initiated.\n\nNeurogenesis was not triggered in response to brain cells being killed through cannabinoid exposure, the researchers add. In fact, HU210 injections did not appear to prompt any loss of neurons in the hippocampus. http://www.medicinenet.com/script/main/art.asp?articlekey=54893\n\nMind you, the study is using a super-concentrated drug form and the verdict is still out on smoking it, but they do suggest THC is the only known drug that actually can reverse the loss of brain cells.\n\nFinally though once again, pot does not change your intelligence and different people react to different drugs differently. But it is possible THC will be a cure in time for certain brain affictions...

It increases the neuronal firings in the areas the stimulant affects. It makes your central nervous system work more.

MOST DRUGS CAN KILL YOU. I HAVE KNOWN OF PEOPLE THAT HAVE DONE ECSTASY FOR THE VERY FIRST TIME AND DIED. I HAVE ALSO KNOWN PEOPLE TO DO CRACK /COCAINE WHICH CAN CAUSE HEART ATTACKS, SEZIURES, STROKES, RESPITORY OR BRAIN ANUERISMS. ICE/CRYSTAL METH HAS MORE OF A PSYCHOLOGICAL EFFECT ON THE BRAIN. ALL DRUGS ARE HIGHLY ADDICTIVE REGARDLESS OF WHAT YOUR FRIENDS TELL YOU. HERE ARE SOME WEB SITES BELOW THAT CAN GIVE YOU A BETTER UNDERSTANDING OF EFFECTS. REMEMBER THAT TAKING ANY TYPE OF ILLEGAL DRUG IS A GAMBLE BOTH LEGAL AND HEALTH.

Melatonin affects the brain chemical balance.  Some who take it, have the opposite affect; hyperactivity.

It depends which drug u r using... but nowdays almost all drugs r safe. long time intake can cause some problems but it is very rare. so take care  of ur heart ..and mind..ignorig medicine results heavy damage to body.

Drugs is basically something that alters the chemistry in your body.  Depending on what type of drugs they can help or hurt the body.

Drugs is the main topic\n1st subtopic is why people use drugs\n<>to be 'cool'\n<>their rolemodel does\n<>pressured into doing it\n2nd on could be why it is bad for u\n3rd can be why it is bad for the environment

This is a complex question.  It depends on why you are taking the drugs.  The same drug that could save your life in an emergency could kill you if taken at the wrong time.\n\nMany recreational drugs might feel good or give you a novel experience, but could have long-term damaging effects.\n\nIt all depends.  \n\nSide note: There is some tentative evidence that marijuana can stimulate the growth of new brain cells.
