what is the most - abused drug in america?\nmarjuana\nalcohol\ncocaine\nlsd

Brief Explanations:

Alcohol is widely available and has a long - standing cultural presence in America. Despite being a legal substance (for those of legal drinking age), excessive and improper use (abuse) is very common. Marijuana is also misused, but alcohol's consumption volume and the extent of its abuse (in terms of health, social, and legal problems related to over - consumption) make it a more prominent abused drug in a general sense. Cocaine and LSD are illegal and their abuse, while serious, occurs on a relatively smaller scale compared to alcohol in terms of the overall population affected by abuse.
