For example, individuals high in positive affect are more likely to engage in risky behaviour, such as drug use. Individuals with high positive affect in response to use are more likely to seek out substances for hedonic reasons. Conversely, low positive ...
For example, NIDA has received a request for cigarettes with an 8% potency. The subcommittee notes that very little is known about the clinical pharmacology of this higher potency. Thus, while NIDA research has provided a large body of literature related to the clinical pharmacology of cannabis, research is still needed to establish the safety ...
The latter reflects physical dependence in which the body adapts to the drug, requiring more of it to achieve a certain effect (tolerance) [25] and eliciting drug-specific physical or mental symptoms if drug use is abruptly ceased (withdrawal). Physical dependence can happen with the chronic use of many drugs—including even appropriate ...

A common example is the effect of D 2 altering drugs (neuroleptics) which can help schizophrenia, but cause a variety of dyskinesias by their action on motor cortex. Modern studies are revealing details of mechanisms of damage to the nervous system such as apoptosis (programmed cell death) and free-radical disruption.
