What does 'tolerance' and 'dependance' mean when it is about drugs?

Answer 1

Tolerance: you're so used to a dosage of a drug that you need more to achieve the intended effect. Example: If you drink a can of beer every day, sooner or later you'll get used to the can of beer and you'll need two to get a buzz.

Dependence: You can't "live" without the drug. Dependence usually means addiction.

Answer 2

tolerance is how resistant you are to a drug. some people will develop a tolerance to a drug which means it wil no longer work, or wont work as well. its like when you start drinking alcohol you get drunk after 2 drinks but then you go out every week and build up atolerance so now you need 5 drinks to get drunk.
if you are dependant on a drug it means you need it (like being addicted) though doesnt necessarily mean a physical addiction, it could just be an emotional dependance, like using a drug to give you confidence or to relax.

Tolerance and Physical Dependence

People who begin taking drugs often do so to achieve a certain effect that they find enjoyable or positive in some way. Prescription medications may be taken initially to treat pain, depression, or anxiety. Improper use of prescription and other drugs (including alcohol) may make a person feel alert, powerful, confident, relaxed, friendly, sexy, or talkative. These rewarding consequences increase the likelihood that a person will continue using a drug. Furthermore, two other important consequences that influence continued drug use are tolerance and physical dependence.

Physical dependence occurs when a person's body becomes accustomed to and dependent on the presence of a particular drug. When the dose is lowered or the drug is stopped, the person will begin to notice withdrawal symptoms. Resuming use of the drug eliminates the withdrawal symptoms. Some withdrawal symptoms feel like a flu bug. The individual may feel hot and sweaty, chilly and shaky. They may develop a runny nose and eyes, and itchy skin. Diarrhea and anxiety may also occur.

Physical dependence is not the same as addiction. Physical dependence is a totally biological response of the body; addiction includes psychological or behavioral factors. A person can be physically dependent on a drug but not addicted to it. For example, a patient who has been in the hospital after major surgery may be put on regular doses of narcotic painkillers. When these are stopped, he or she may notice symptoms of withdrawal. This person has become physically dependent on (but not addicted to) painkillers.

When drug users become tolerant to a drug's effects, they must increase the dose to feel the same effects of the original dose. An individual being treated for severe pain may develop tolerance to a

Tolerance:- Becoming more and more used to the drugs effect. Thus, larger quantities are required to elicit the same effect.

LSD is a classic example, whereby the 3rd or 4th day, little or no effect occurs, though the first dose may be literally 'mind-blowing'
Dependence:- When the drug is withheld, a psychological &/ or physical craving is elicited, to a greater or lesser extent, depending on the duration &/or its dependence potential.
