In doing so, they provide harm reduction strategies for those who choose to drink. This means that moderate drinking goals may also be considered, recognising that any steps toward safer alcohol consumption are steps in the right direction. Consequently, while abstinence may be the optimal outcome for some people, skills for drinking in a way that will minimize harm can be considered if abstinence is not viewed as realistic, attainable, or attractive. For example, blood alcohol concentration level estimation training enables people to set limits for moderate goals that are unique to their gender, weight, and time spent drinking. Teaching practical strategies for reaching these limits, such as spacing one's drinks, pacing oneself, alternating alcoholic and non-alcoholic drinks, consuming food before drinking and drinking for promote success.
