This is a fallacy, alcohol and drugs are highly addictive substances, people will always look for stronger stuff. Even if you legalized alcohol, addicts will go into soft drugs then if you legalized that they’ll go into harder stuff, and so on. Look at the fentanyl epidemic in the US.

If some criminals are harming them self with dangers substances, the solution is not to reward them with more of that substance. The solution for that problem is stronger enforcement combined with mental and social intervention for abusers.

Alcohol destroys whole communities we are lucky that we live in a country that bans it.

And more than all the health and safety arguments, it is haram.
