Have you done LSD, psilocybin or mescaline? You are no more likely to exhibit symptoms of mental illness or find yourself in mental health treatment, says a new study from Norway. Johns Hopkins School of Medicine psychiatry department psychologist Matthew W. Johnson says,

There seems to be no evidence of overall negative impact — and even some hints of benefit — associated with the use of psychedelics.

Psilocybin relieves anxiety in cancer patients and LSD can treat alcoholism symptoms… in a controlled environment. 1 in 76 Americans age 21-64 have tried psychedelics, according to NPR, and they are hereby excused.

But please don’t go dropping a mountain of acid, please. Dosage and prior history of mental illness — extremely important, unpredictable factors — have not been taken into account in this study.

And dosage is important. Dosage determines the difference between this lovely LSD trip…

…and this not so lovely LSD trip.
