The term 'Dropped Drug' refers to two substances, LSD and ACID, which are both illegal drugs. LSD, or lysergic ACID diethylamide, is a hallucinogenic drug that was first synthesized in 1938 and has been used recreationally since the 1960s. ACID, or lysergic ACID amide, is a psychedelic drug that produces visual and auditory hallucinations. Both drugs have been linked to mental health issues and can be dangerous if taken in large doses.
