Sometimes the effects are more subtle. Someone may simply become quite and withdrawn. Often these changes are not necessarily dangerous or problematic, but there are times when they certainly can be. Some of the more serious changes may be things like violent tendencies , lack in ability to make good or safe decisions, or lack of use of protection when engaging in sexual situations. Studies have been done on each of these circumstances.
People often drink to relax, to gain confidence, or to be at ease in social situations.
The problem with this thinking is that while alcohol may in fact be able to provide some of these benefits, it also can cause the exact opposite. Every time alcohol is consumed, in every person, perception and thought are generally impaired. We may respond more extremely to a situation because alcohol prevents us from using the cues that would inhibit a response. Alcohol intoxication can decrease one's ability to consider the consequences of their actions and it can also lower inhibitions about sexual behaviors. Often times, alcohol plays the role of scapegoat.
