Here is a basic checklist frequently used by counselors to see if alcohol and other drug abuse may be an issue in someone's life.

• Does the person report or appear to be frequently high or intoxicated?
• Do recreational activities center around drinking or other drug use, including getting, using, and recovering from use?

• Does the immediate peer group of the individual suggest that substance abuse may be encouraged?
• Is the person socially isolated from others and is substance abuse occurring alone?
• Is the person reluctant to attend social events where chemicals won't be available?

• Does the person use "social drugs" with prescribed medications?
• Does the person use more than is safe in light of other medications they may be using, or because of compromised tolerance due to illness or disability?
• Does the person have an elevated tolerance as evidenced by the use of large quantities of alcohol or other drugs without appearing intoxicated?

• Are there predictable patterns of use which are well known to others?
• Is there a reliance on chemicals to cope with stress?
• Has the person made lifestyle changes yet the drug use has stayed the same or increased? (eg. changed friends or moved to another area)

• Does the person rely on drugs as a means of coping with negative emotions?
• Does the person believe that pain can't be coped with without medication?
• Does the person obviously feel guilty about some aspect of their use of alcohol or other drugs?

• Are there medical conditions which decrease tolerance or increase the risk of substance abuse problems?
• Are there medical situations which are aggravated by repeated alcohol or other drug use?
• Did the person ever suffer an accident or disability while under the influence, even if it is denied by the person?

• Have important relationships been lost or impaired due to chemical use?

• Has the person been in trouble with authorities or arrested for any alcohol or drug related offenses?
