Can the test be beaten?
Very little in life is beyond the range of possibility. Yes, it is possible to beat a polygraph examination deliberately. The more appropriate question would be, "Are those efforts likely to succeed?" The answer to that is no. Polygraph examiners are familiar with all of the usual means that liars have used to try to produce favorable results in polygraph examinations. If you're thinking of trying something you've read about on the Internet, remember that the examiner has read the same information. Most persons trying to beat a polygraph examination are so awkward and unskilled in their attempts that their efforts are easily detectable. Generally, the harder someone tries to "beat" the test, the more he enhances his deceptive reactions. The best advice for liars is simply don't take the test.

Use of drugs and medicines
Drugs and medicines do not generally have any adverse impact on a polygraph examination. Prescription medications should be continued in the prescribed doses. The effect of any drug, whether legal or illegal, is not specific with regard to any particular question in the examination. Excessive amounts of any drug can occasionally cause an inconclusive result, but excessive drug use is usually apparent from both a person's behavior and his polygraph charts.
