Suggesting that a person with a gambling disorder stop gambling when it ceases to be fun might, arguably, do little to prevent harm. The point at which the transition from being in control to gambling compulsively occurs might be difficult to determine, given that the public is bombarded with enticements and opportunities to gamble. Moreover, systems that enable the limitation of losses, such as binding precommitment systems, are often unavailable.

However, there is insufficient evidence to suggest that there is indeed a safe level for use of many gambling products. At a population level, the concept of a safe level of gambling could be misleading. At present, messages are not tailored effectively to individual circumstances. In addition, it is not possible to readily predict which individuals might experience gambling-related harm.
