According to the sources provided, occasional alcohol use can potentially lead to addiction. The National Institute on Drug Abuse (NIDA) explains that addiction is a chronic disease that can develop from repeated drug or alcohol use, including occasional use [3]. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) also notes that addiction to alcohol can develop over time, and that individuals who drink occasionally are not immune to the risk of addiction [2].

The NIAAA explains that addiction to alcohol can occur in a cycle, starting with the initial use of alcohol, followed by an increase in use, and then the development of tolerance and withdrawal symptoms [2]. This cycle can continue and lead to addiction if the individual continues to use alcohol despite negative consequences.

Furthermore, Drug Patent Watch notes that alcohol is a drug that can cause physical dependence, and that individuals who consume alcohol regularly can develop a tolerance to its effects, which can lead to increased consumption and addiction [1].

In conclusion, occasional alcohol use can potentially lead to addiction. Addiction is a chronic disease that can develop from repeated use of drugs or alcohol, including occasional use. Alcohol can cause physical dependence, and individuals who consume it regularly can develop a tolerance to its effects, which can lead to increased consumption and addiction.
