Which drug is associated with the street names "Hug Drug" and "Love Drug"?

MDMA, commonly known as "Ecstasy," is associated with the street names "Hug Drug" and "Love Drug" due to its effects that promote feelings of empathy, emotional warmth, and connection among users. The drug enhances sensory perception and creates a sense of closeness and affection, leading to the affectionate names it has garnered in various subcultures, particularly among those in dance or rave scenes.

The other substances listed have different effects and cultural implications. Cocaine is known as a stimulant that increases energy and euphoria but does not carry the same associations with love and affection. Marijuana is often associated with relaxation and altered perception, lacking a specific connection to the feelings of love described with MDMA. PCP, known for its dissociative effects, has a reputation for causing agitation and confusion rather than the social bonding attributed to MDMA. Thus, MDMA stands out as the correct answer due to its unique association with feelings of love and connection.
