“What is the most harmful drug? Many people assume the answer to that question is heroin or methamphetamines. While these substances are without question dangerous, alcohol is considered the most harmful drug. But why does this legal substance have the potential to be so dangerous?

Alcohol is regarded differently than the other most dangerous drugs. As a legal substance, alcohol doesn’t seem to be a drug on most people’s radars. Drinking is socially acceptable and often glamorized. With an accepting social attitude and legal status, alcohol is easy to incorrectly regard as harmless. This approach can make it easier to use alcohol.”
