The Effects of
Drugs and Alcohol


Handwriting can be impacted by mood, environmental and health changes. When drugs and/or alcohol consumption are introduced into the writer's system, the effects are clearly seen.

      A study published in the Journal of Pediatrics (Vol. 9 No.1. pp. 127-132, July 1977) reports the use of handwriting as measurement criterion of the effects of Ritalin in hyperactive children. The first writing sample was that of a nine-year-old hyperactive boy before treatment: the second sample is his writing after four weeks of placebos: the third sample is his writing after two weeks of Ritalin therapy.

      The changes that can occur when drinking alcohol are clearly observed as seen in the House of Seagram' publication warning against driving while under the influence of alcohol.

Writing reflects changes brought on by the mood, environmental influences, or health. The effects are also revealed in writing, as shown by this House of Seagram's publication warning against driving while under the influence of alcohol.

      The more you drink, the more coordination you lose. That's a fact, plain and simple.
      Still, people drink too much and then go out and expect to handle a car.
      When you drink too much you can't handle a car.
      You can't even handle a pen.

                                    — The House of Seagram

Handwriting reflects changes induced by alcohol.


Drugs also cause changes in one's handwriting. A study published in the Journal of Pediatrics (Vol. 91, No. 1, pp. 127-132, July 1977) reports the use of handwriting as a measurement criterion of the effects of Ritalin in hyperactive children. The first writing sample is that of a nine-year-old hyperactive boy before treatment; the second sample is his writing after four weeks of placebos; and the third sample is his writing after two weeks of Ritalin therapy.
