Am I consuming larger quantities or consuming for a longer period of time than I would like to?
Would I like to reduce my consumption but feel unable to do so?
Do I spend a long time trying to get hold of the substance, taking the substance or recovering from its effects?
Do I spend increasingly more money consuming?
Do I feel a need to take it or to take more and more of it?
Is my use of it making me avoid taking care of my responsibilities or carry out day to day tasks?
Do I carry on using, even though I am aware it is causing problems in my daily life?
Have I stopped going to, or participating in social engagements, important work –related or leisure activities because of my consumption?
Do I continue to consume even if I am in a situation or environment which could be considered risky or dangerous?
Do I continue to use even though I know I am suffering from a physical or psychological problem?
Do I need to take more and more to get the same effect as I used to from the substance (has my tolerance increased?).
Do I suffer from withdrawal symptoms when I don´t use, which are relieved when I consume again? (strong cravings).
