Alcoholism
Alcoholism, also known as “alcohol dependence,” Includes four symptoms: Craving: A strong need, or compulsion, to drink. Loss of control: The inability to limit one’s drinking on any given occasion. Physical dependence: Withdrawal symptoms, such as nausea, sweating, shakiness, and anxiety, occur when alcohol use is stopped after a period of heavy drinking. Tolerance: The need to drink greater amounts of alcohol in order to “get high.”
Horizontal Gaze Nystagmus (HGN)
Horizontal gaze nystagmus is a naturally occurring involuntary jerking of the eyeballs as they gaze side to side. It is theorized that when a person is impaired by alcohol, the nystagmus (the jerking of the eyeballs) is magnified or pronounced.
Excessive Drunkenness
A state of drunkenness in which a person is so far deprived of reason and understanding that he or she is incapable of understanding the character and consequences of an act.
Impairment
Well known is the fact that the consumption of alcohol can cause impairment. Perhaps less recognized is that fact that impairment rises gradually at lower levels but dramatically at higher levels of blood alcohol concentration (BAC).
Controlled Substances
Health and other public concerns have generated detailed Federal and state regulation of the sale and possession of alcoholic beverages, tobacco products, and a wide range of other "controlled substances."
Legal State Limits
Laws for DWI and DUI vary from state-to-state. There is a chart listing state blood alcohol limits, license suspension, ignition interlock and forfeiture penalties.
