It is also quite common for people to drink and become drunk.
Drugs, however, are only taken to become intoxicated on the drug,
That's how the drug alcohol was used when that drug was illegal.
And usage typically increases over time; very few people can control their use to mitigate the destructive effect on their lives (again, most of us have seen this firsthand).
What some of us have seen is certain individuals not controlling their use - some of us have also seen individuals controlling their use. And even someone who has seen only the former should understand that their personal experiences are not randomly selected and so are not reliably extrapolated to the population at large - and that since users who control their use are also careful to not be seen breaking the law, not seeing them doesn't mean they don't exist.
The Biblical argument is simpler - the Bible exhorts us to refrain from drunkenness.
But not to ban alcohol. Thanks for the pro-legalization argument.
