The Olympic have a zero tolerance drug policy, Marion Jones was stripped years after she won her medals.
If a college has a alcohol and drug policy, it is probably a ban and a zero tolerance for these behaviors. Depending on how the policy is written, a student could face discipline or even be expelled. If there is illegal use (underage drinking; illegal drug use), the college cannot risk a student's bad behavior.
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 military, and the Navy specifically have a No Tolerance policy. If you come up positive, you will be punished. And it used to be three strikes and you are out, I believe it still is.
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.
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.
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.

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.
