Subjects were recruited from schools; they were told that they would take part in an informative study about marijuana. While those who smoke weed, they were recruited in the experimental and control group. Inclusion criteria were history of smoking and smoker or non-smoker. Also those who have cigarette addictions where excluded. Subjects who smoked weed only were used, however, subjects with any other addictions were also excluded from the study. In order to collect the data, I used tallies of correct answers before the game was played and after.

Responses were measured in tallies and also by the number of chips a person had at the end of the game. Initially gamers were given 3 chips, if the individual guessed the answer correctly they lost one chip. If the individual had the same card after two times of the game going around they gain another chip. The person with the less number of chips wins the game. The game was presented to substance users in order to test their knowledge of marijuana. In the non-experimental condition they were given a questionnaire. In the experimental condition the smokers were asked to smoke weed and play the game. The whole process of the study will use within game subject design which will basically utilize the same subjects but in a pretest- posttest manner, which will measure the effect of the game on increasing knowledge of marijuana.

Data was collected by research assistants who recorded the correct number of answers. Subjects were explained how to play the game through given game instructions, which explained the rules of the game and how to play the game. Data conveyed that there was no relationship in the number of correct answers in both the experimental and control groups. So results were inconclusive of whether the game Cloud Nine, helped as a better informant of marijuana. There was no real difference in the means in the control and experimental conditions. Due to repeated exposure there was a regression to the mean in both conditions.
