Many secondary metabolites of plants have medicinal properties. It is their misuse that creates problems. Justify the statement with an example.

(N/A) Many plants,fruits,and seeds possess hallucinogenic properties.
$\Rightarrow$ These have been used for centuries in folk medicine,religious ceremonies,and rituals across the globe.
When these substances are consumed for purposes other than medicinal use,or in amounts/frequencies that impair an individual's physical,physiological,or psychological functions,it constitutes drug abuse.
For example,$Morphine$ is a secondary metabolite obtained from $Papaver$ $somniferum$. The acetylation of $Morphine$ produces $Heroin$,which is a highly addictive drug.
