After so long a persons body will just adjust to the chemical. It is like drinking coffee. The first time we drink a cup we feel wired and after a few years 1 cup is just not enough

Physical dependence occurs when a person develops a tolerance to the effects of a drug and needs larger and larger doses to achieve intoxication or another desired effect.

It will heighten the tolerance pretty fast.

Tolerance and dependence of a drug is a trademark of addiction. The tolerance of a drug builds in which case a person needs more of the drug in their system. The dependence on a drug, is the need for the drug in which to feel like you are living a normal life.

Repeated exposure to a stimulus could increase the development of drug tolerance.

The Olympic have a zero tolerance drug policy, Marion Jones was stripped years after she won her medals.

Hrm.... the first one that comes to mind is DMT. You've got about a minute to get your fill of it before your tolerance is built up. This tolerance diminishes fairly quickly too though.

Yes. There are some drug effects for which people CANNOT develop tolerance. Of course there are other drug effects which commonly cause people to develop tolerance. If you have specific drugs and effects in mind, let me know.

Tolerance means that an increased amount of the drug is needed to achieve the same effect as before. Dependence can be physical or psychological. Dependence is referring to a need for the drug in order to function normally. Someone that is dependent on a drug likely has a high tolerance for the drug. However, someone can have a high tolerance for the drug and not go through withdrawals or have other negative effects when the drug is not used anymore.

The drug itself does not have a higher tolerance-the drug user has the tolerance,let's say you are able to do 400mg of Oxycontin a day and you have been doing this for a couple weeks,well then yes YOU ARE GOING TO GO THRU TOTAL HELL!!!!!!

User Avatar

Yes and No. Yes...Stopping a drug for a period of time, Often called a Drug Holiday is done to reduce the tolerance. When the drug is restarted; however, the patient more quickly reaches the tolerance threshold than he/she did the first time.

Tolerance is like an immunity that your body makes. If you use a drug, your body will often build tolerance and dull or even nullify the effects.

User Avatar

It doesn't. It is not an addictive drug. It does not confer tolerance or dependence.

it can reduce the effect of the medication

Yes, tolerance can develop to mescaline, especially when one doses on consecutive days. Cross-tolerance between mescaline and other psychedelics is also possible. Nevertheless, the tolerance usually fades quickly with abstinence from the drug.

Tolerance to a drug (so that higher and higher amounts are needed in order to obtain the same initial effect) and dependence - both are part of the physical addiction. Psychological addiction does not involve physical tolerance and dependence, but can be difficult to treat, unless there is motivation to kick the habit.

User Avatar

It means someone requires a higher doseage of a drug to acheive the same effects.

User Avatar

This is called tolerance. Tolerance is built up by using a drug repeatedly over a period of time. This is true for pharmacutical drugs, as well as illegal substances, and alchohol. As a person's tolerance grows, they may need more amounts of the drug, and may need it more frequently.

No, pain tolerance and drug tolerance are two almost completely different things. Pain tolerance is mostly psychological; basically how much discomfort you can take before you cave. If a person lives with chronic pain or painful injuries for an extended period of time, the person can eventually get used to it. The mind eventually can rework itself to set that level of pain as its zero point. You still feel the pain, but it doesn't bother you anymore. Drug tolerance (ie painkillers) is physical: your brain is used to a certain level of the drug, and requires more of the drug to feel the effects. Drug tolerance is often the immediate precursor to drug addiction. People with high tolerances for pain often become tolerant of painkillers sometime in their lives, but eventually stop relying on drugs at all.

Drug tolerance is the ability to withstand increasing amounts of a drug without reacting to it

When does drug resistance occur*

User Avatar

No the only way to reduce tolerance is to not use the drug for a period of time.

Tolerance is the largest amount of error that can occur during its operation. Depending on the nature of the instrument, tolerance may sometimes be quoted instead of accuracy
