In addition, because tolerance occurs rapidly, users might need ten times as much drug in as little as ten days. In fact, there is almost no limit to the development of an opioid (heroin) tolerance.
This tolerance can develop at different rates for different body systems, such as the body can develop a high tolerance to:
However, the body does not develop a high tolerance for body functions such as:
Pain relief and the desire for pleasure along with tolerance, tissue dependence and the fear of withdrawal are the main reasons for heroin’s addictive nature. The body’s ability to adapt to the effects of the drug can alter the brains chemistry. Sometimes this is a permanent alteration of brain function. Therefore, when chronic heroin stops, the body has less ability to produce its own dopamine and the user has less ability to feel elated or normal.

Unfortunately, since acute opioid withdrawal symptoms can be extremely painful and seem so frightening, creating anxiety, the fear of withdrawal becomes a greater trigger for continued use of the drug than the desire to have the rush.
