Love is best described by Merriam Webster as "unselfish, loyal and benevolent concern for the good of another" and "strong affection for another arising out of kinship or personal ties", a "a feeling of strong or constant affection for a person". That is love. According to Merriam Webster, marijuana is "the dried leaves and flowers of the hemp plant that are smoked as a drug" and "the dried leaves and flowering tops of the pistillate hemp plant that yield THC and are smoked in cigarettes for their intoxicating effect".

Merriam Webster also describes sex as "a physical activity in which people touch each other's bodies, kiss each other, etc" and "the sum of the structural, functional, and behavioral characteristics of organisms that are involved in reproduction marked by the union of gametes and that distinguish males and females".

There's "keep the peace", which means to maintain order and "at peace", which means someone is dead or the untroubled, content mood according to two dictionaries I read as well as the meanings "re-establish friendly relations; become reconciled" and the term "hold / keep one's peace" meaning to refrain from or cease speaking; keep silent.

I got those all from credible sources. Please explain to me how these terms peace and love are related to drug abuse and sex. And don't use the "when two people are in love, they have sex". Because not everyone who does sex is in love. Peace and love are separate from drug abuse and sex.
