Physical dependence requires an individual to acquire the material to avoid withdrawal physiological warning signs taking place with all the cessation of material use. Tolerance to some material takes place when improving doses of the compound are mandated to achieve the specified outcome. Cross-tolerance could be the improvement of tolerance to at least one substance as a result of using an alternative.

Learning would be the acquisition and storage of data to be a consequence of expertise. Calculated y an increase in the likelihood of the individual habits in response to some stimulus.
