That's how the drug alcohol was used when that drug was illegal.
The Biblical argument is simpler - the Bible exhorts us to refrain from drunkenness.
But not to ban alcohol. Thanks for the pro-legalization argument.
The only purpose to taking drugs is drunkenness. Alcoholic drinks are part of eating and drinking, drugs are not.
Marijuana brownies are eaten.
Drugs have one purpose - getting drunk.
As I already noted above, criminalizing a substance has been shown to increase the degree to which its use goes beyond mild 'relaxation' to outright intoxication - becasue there's less exposure to legal consequences if one concentrates one's use into as few separate episodes as possible.
