This includes inpatient and outpatient rehab options. The symptoms displayed are not physical. While we all experience altered states of consciousness in the form of sleep on a regular basis, some people use drugs and other substances that result in altered states of consciousness as well. Cross-dependence usually occurs among compounds of a given family of drugs. There is considerable evidence, however, that the organismâs experience with the drug administration environment, as well as the drug, often importantly contributes to tolerance and dependence. When the drug begins to exert its effects on the body, the brain detects the existence of an alteration in its balance or homeostasis.

Before going any further, it is necessary to enlarge upon the term and define what tolerance means. Drug tolerance can be generally defined as . There are several hypotheses about how tolerance develops, including opioid receptor phosphorylation (which would change the receptor conformation), functional decoupling of receptors from G-proteins (leading to receptor desensitization), mu-opioid receptor internalization and/or receptor down-regulation (reducing the number of available receptors for morphine to act on), and upregulation of the cAMP pathway (a counterregulatory mechanism to opioid effects) (For a review of these processes, see Koch and Hollt. It should be pointed out that the term tolerance is frequently employed improperly and thus generates as much confusion as it does clarity.
