Ellen G. White's writings describe masturbation as a "vice" and associate it with negative physical and moral consequences. She refers to it as a violation of natural laws and suggests that it can weaken the constitution and enervate the entire system, especially as young people mature into adulthood. She also emphasizes personal accountability for one's actions in this regard.
