Depends on if you are post puberty or haven't went through puberty. It reacts differently depending on that. If you haven't went through, it is affective for ADHD, but if you have then it reacts totally opposite and is a stimulant. Back when my cousin was a medical student, they were taught that Ritalin is sold on the streets as "speed". Prescription diet pills many years ago were just "speed". That is why so many homemakers got hooked on diet pills and it made a real mess for their lives. It really messes with your mind bad if you are past puberty.

it depends of your metabolism. if you need to pass a kind of test or something you should know that ecstasy stays like a month in your body.

well you took it for five days, so it had a chance to build a level and it is metabolized thru the liver, you can have traces for up to a month.

I have been searching and all the literature and the side effects listed are all short term, there is no mention of long term effects.  I would think that the experts know very little about this as Ritalin is a relatively new drug.\nYou have been on some pretty serious drugs in a short time frame, maybe its the combination rather than just one drug which has caused your problems.\nI feel for you, its rotten on top of the problems you have already had.  I hope you find a satisfactory answer to your question...good luck x

If you have done coke only one time.... It can be gone as soon as the next day. \n\nother drugs can/will stay in your system longer.\n\nWhen they are testing w/ hair, I under stand it to be much longer that they can find stuff in your system.

Nothing to do but wait.  Depending on how much is already in your system, it could take 2 weeks to a month for it to be completely gone.  There isn't a thing you can do to speed that up.

First I would ask how old the child is.  As a teacher I can tell you that ritalin is one of the most overprescribed drugs in the U.S.  People have forgotten that little children are naturally hyper.  If the child does not chemically need ritalin, it will make him more hyper.  If he does, you can expect him to be kind of blah, as ritalin is a stabalizer.  Although I am not a doctor, unless the child is bouncing off the walls uncontrollably, and can't pay attention for more than a few seconds, I do not recommend drugging him.  I have had many students who were presribed these drugs and only two or three that I felt really needed them.

Taking pills is not a good idea unless you have a prescription. Vicodin is highly addictive and is in the opiate family (same as morphine/heroine) With that said, depending on how many you are taking each day, it can stay in your system anywhere from 3-5 days. I have seen people taking these pills and it take 30 days until their body has fully gone back to normal but that is at taking numerous pills a day. Please be careful with this medication.

b) 16.5 hours\n\n66 hours/4 half lives = 16.5 hours\n\nYou start with 40 mg.  After 16.5 hours, you're left with 20 mg.  After another 16.5 hours, you have 10 mg.  After another 16.5 hours, you have 5 mg.  After yet another 16.5 hours, you have 2.5 mg.

Depends on what drugs you are talking about. It's different for every drug. Marijuana can stay in your system for up to 30 days. Pain pills 3-5 days. Drugs are BAD and you shouldn't even be concerned with this. Don't use okay! Good luck to you and have a great day!!!

It will go out of your system in 30 days. I think your in the clear. If your worried, you can buy at home drug tests from CVS, walgreens, and the internet.  The pharmacy stores have more accurate ones.  If you want to really make sure, take some water pills and drink a lot of water.

Every person experiences different side effects.  \n\n\nRitalin is a stimulant and is the brand name for Methylphenidate.  This stimulant acts primarily by releasing dopamine.  Dopamine is a neurotransmitter that leads to greater activity.  It is also a hormone that plays a role in feelings of pleasure and is intimately involved with the motivational process.  As a result, the drug may improve attention and decrease distractibility in activities that normally do not hold the attention of children with Attention Deficit Hyperactivity Disorder.\n\nRitalin affects a normal brain differently, and it can make you sick.  For the person with normal brain function, there are many potential side effects including elevated blood pressure and heart rate, nausea, agitation, headaches, and insomnia, etc.\n\nFor the peole who need it: Some problems that people have had with Ritalin are:  changes in appetite, stomachaches, headaches, sleep disturbance, potential exacerbation or tics, irritability, rebound hyperactivity, growth problems, and, very rarely, drug induced hallucinations.\n\nA major misconception about Ritalin is that it has a paradoxical effect, calming people rather than stimulating them.  In fact, the effects of low?dose stimulants, including Ritalin, are the same on children and adults, ADD or not.\n\nAlso, some people become moody or irritable as the medication wears off at the end of the day, and a few report headaches or stomachaches.
