Discrimination against drug addicts that suffer with an addiction, only a few will receive treatment due to the complexity of health care systems. Most health care systems do not have insurance coverage for addiction recovery and many health care providers have little to no training in treating addiction. Some doctors do not feel comfortable treating an addiction due to their lack of knowledge and training of the topic. This is one of the reasons why drug dependence is difficult to recover from. Among injecting drug users, the incidence of HIV infection is higher than among other drug addicts, however punitive and discriminatory measures against
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
