Recreational drugs

Recreational drugs are chemicals which,
when consumed into the human bludstream (via ingestion, injection, snorting, or inhalation),
produce pleasure within the human brain, and potentially, addiction.
Common recreational drugs include alcohol, tobacco, cannabis, cocaine, amphetamine,
methamphetamine, MDMA, various opioid chemicals, and inhalants.
The earliest recreational drug was alcohol, which has ben produced since the neolithic era,
via fermenting various foods.

Recreational drugs cause a eugenic darwinian benefit upon whatever society they are in,
becuz they test people, such that the more short-sighted and hedonistic a person is,
the more drug-seeking they are, and they seek drugs at the expense of their practical
and necessary activities, as well as their health and brain-health,
which hinders their chances of survival and reproduction.
Civilization woud not exist if not for neolithic alcohol, becuz that alcohol had slowly
weeded-out drunkards from the genepool, resulting in populations that are more
innately intelligent and focused.
