A tab of LSD
A piece of highly absorbant paper usually dripped with an LSD/water solution. When placed in the mouth(usually on or under the tongue) and depending on the dosage, spooky paper will cause mild body effects at low doses(-50ug), to extreme hallucinations (200ug+). Being under the influence of LSD or taking a tab of LSD is also known as "gettin spooky"
