Any analgesic or sedative will be proportionately as addictive as it is effective. In fact, most people are unaware that there is more than one type of tolerance. Psychoactive drugs have the ability to mix with the natural chemicals in the brain. With a higher dosage comes a higher chance of drug addiction.

Also, there is cross dependence wherethe ability of one drug to suppress the manifestations of physical dependence produced by another and to maintain the physically dependent state. The amount of drug-metabolizing enzyme has increased because the administered drug has induced the organ(s) in which the enzyme is present to synthesize more of the enzyme - this is an example of the effect of "enzyme induction" briefly described in Pharmacokinetics. Occurring simultaneously with tolerance is another physical phenomenon, dependence. In fact, even people who are on legitimate pain medication, sleep medication or other legitimate prescriptions can fall victim to tolerance and the eventual dependency and outright addiction that comes shortly after with continued use.

The state of physical dependence is revealed by withdrawing the drug and noting the occurrence of withdrawal symptoms. Not all drugs are addictive, but many common drugs, such as amphetamines (Adderall) and opiates (Oxycodone), are. A person can become used to a setting they use a drug at, and not feel the effects of the drug. Tolerance cuts across drug types without regard for what substance the person is abusing; e.g., tolerance can develop from abusing opiates as well as stimulants like methamphetamine.
