Drug education Drug education Drug education is the planned provision of information, resources, and skills relevant to living in a world where psychoactive substances are widely available and commonly used for a variety of both medical and non-medical purposes, some of which may lead to harms such as overdose, injury, infectious disease (such as HIV or hepatitis C), or addiction. Planning includes developing strategies for helping children and young people engage with relevant drug-related issues during opportunistic and brief contacts with them as well as during more structured sessions. Drug education enables children, youth and adults to develop the knowledge, skills and
Novikov's condition Novikov's condition In probability theory, Novikov's condition is the sufficient condition for a stochastic process which takes the form of the Radon–Nikodym derivative in Girsanov's theorem to be a martingale. If satisfied together with other conditions, Girsanov's theorem may be applied to a Brownian motion stochastic process to change from the original measure to the new measure defined by the Radon–Nikodym derivative. This condition was suggested and proved by Alexander Novikov. There are other results which may be used to show that the Radon–Nikodym derivative is a martingale, such as the more general criterion Kazamaki's condition, however Novikov's condition is
