Answer:
Drug abuse refers to the non-medical or inadequate form of recurrent consumption of chemicals that affect a person’s mood or behavior. The term “psychoactive substance” or "drug" is used as a neutral and capacious term for a whole class of substances prohibited and permitted.
Such substances are usually both legal and illegal drugs (amphetamine, cocaine, cannabis, opiates, ecstasy, LSD), alcohol, as well as psychotropic drugs (tranquilizers, barbiturates).
By abuse is meant a use that is harmful, for example because the substance is taken in excessive quantities, taken in harmful combination with another substance, or taken strenuously without any medical basis. Substance abuse can in the symptom picture be similar to habitual disorders (impulse control disorders) and self-harm behavior.
Debate about the practice of using various psychoactive substances has been going on since ancient times. The abuse of such substances negatively affects the lives of not only their direct users, but also of their relatives and the whole society.
Answer:
Transient Equilibrium
Explanation:
[source; wikipedia]
In nuclear physics, transient equilibrium is a situation in which equilibrium is reached by a parent-daughter radioactive isotope pair where the half-life of the daughter is shorter than the half-life of the parent. Contrary to secular equilibrium, the half-life of the daughter is not negligible compared to parent's half-life. An example of this is a molybdenum-99 generator producing technetium-99 for nuclear medicine diagnostic procedures. Such a generator is sometimes called a cow because the daughter product, in this case technetium-99, is milked at regular intervals.[1] Transient equilibrium occurs after four half-lives, on average.[2]
(i hope this sort of helps? :"] )
I think it's D. Because the students impulse is to do it because its cool, because all their friends do it. Hope my answer helps you! :)
