Abstract:
The use of psychoactive substances by offenders is a major preoccupation among correctional network clinicians, researchers and administrators. However, very little is known about this phenomenon during incarceration. The research presented here explores patterns of inmate drug use during imprisonment. Selected at random, 317 respondents in 10 Canadian penitentiaries were interviewed in 1999 to complete self-reported questionnaires. The data indicate various types of important changes, notably with regard to substances used, frequency of use, motivations for use, and inmates' perception of their psychological state during periods of intoxication.

Drug Delivery: Parenteral Route
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
Factors Affecting Drug Distribution: Physiological Barriers
The capillary endothelial barrier allows only smaller molecules below 600 Da (Daltons) to pass through. It also restricts drugs like heparin that are bound to blood components, limiting their movement within the bloodstream.
