This classic Urban Legend stated just that: that after seven hits of LSD once was considered, in the eyes of the law, to be legally insane. Lots of different varieties exist, including the famous Six Hits of Acid and You're Legally Insane and the ever popular One Hit of Acid... These generally run along the same lines as people tripping and peeling themselves like an orange, babysitters tripping and putting the baby in the oven and the turkey in the crib, and people getting sore backs from the strychnine that the dealers politely cut their LSD with.
