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.
A psychological dependence is a person's belief that he or she needs a drug to feel good or to function normally. A physical dependence is a condition where a person has a physical or chemical dependence on the drug.
Addiction
Drug addiction is not related to normal behavior. You become irritable with friends and family. You have problems with remembering things, and problems on the job. Also you have an overwhelming desire for the next drink or drug. And if you suddenly stop the drug, you will go through unpleasant psychological and psychical withdrawal. An addictive person will feel normal when they get the next "fix".
Physiological dependence = result of constant use of a drug to the point whereby the body's normal state is the drugged state, i.e. the drug is needed in order to feel normal. Physiological dependence develops with the gradual increase in the body's tolerance to the drug. Tolerance means that more and more of the drug is needed to get the desired effect. Without this increase, the drug user can actually suffer from withdrawal symptoms. Physiological dependence called chemical dependence.Psychological dependence = a drug user's tendency to change his life because of the drug and to centre his/her activities around the drug (acquiring it, using it, experiencing it).
We feel strange and false or seem true or normal They seem false or strange and feel normal or true. They can feel false to seem strange. There is a person strange to make them be normal as this result. There be this person normal in that world.
THC is what makes you high, when talking about Marijuana. Once you smoke enough you can get a certain dependence, much like any drug you take/smoke. Without the drug your mind will feel weird, although your brain would be going back to normal, the drug has tricked your mind that it needs the drug. As to be called a user. So without the drug your brain has withdrawal's, making you want more.

You are addicted when you no longer feel normal without the drug. The dosage has nothing to do with it.
