[The evaluation of methods of usage of addictive substances among high school students and Gdańsk University students].

Anonymous questionnaire examination was performed among 222 high school pupils and 301 students of Gdańsk Medical University, including 210 men and 313 women from 18 to 35 (mean 20.8 +/- 2.56) years old. Marijuana was used by 31.2% of them (once a week or more often 3.82%), amphetamine and Ecstasy by 9.4% (once a week or more often 1.52%), LSD by 3.8%, hallucinogenic mushrooms by 3.1%. Opium alkaloids, peyotl, jimsonweed were taken by a few pupils. The frequency of the drugs usage was significantly higher among school pupils (42.8%) than among Medical University students (30.2%) (chi 2 = 8.80; p < 0.003). Men applied drugs about twice as often as women and the difference was as well statistically significant (chi 2 = 12.95; p < 0.0003). 29.5% men and 25.2% women were cigarette smokers, but only in more advanced smokers (5 cigarettes and more per day) there was a significant difference between male and female (chi 2 = 8.69; p < 0.004).
