Back in the late 1970s and early 1980s, LSD was dispersed on the street as dots dried on little strips of paper. In 1981 this was posted about the LSD stamps. Their designs were attractive to kids, resulting in an outbreak of young children on LSD in Suffolk County. This is from the poster the County Health Department put on display throughout the county that year. It was to inform teachers about these stamps being sold at schools.
