Most likely, neither one nor the other.
It is worth remembering that alcohol is also a drug, only in our country it is considered normal, probably because it is legal. But he is quite dangerous if you do not know the measure.
In the same case, if for some reason it was necessary to make a choice - I would choose, probably, the safest drug among those available to me.
Alcohol is also a drug. Moreover, it is dangerous, heavy and not with the most pleasant effect. And what is usually called drugs are hundreds and hundreds of different substances, from almost harmless marijuana, LSD and kata to creepy things like screws, JWH (spice), heroin. And strictly speaking, only opiates, such as morphine, are drugs. So my choice would be marijuana and psychedelics. If they were legalized, I would almost completely give up alcohol.
Alcohol is a drug. Dangerous, legal.
The fact of the legality / illegality of a substance will not interfere with the choice of a person.
Now, a small lyrical digression:
"Drugs" have always been, are and will be, whoever and how would not fight them, no matter how billions of money are spent on their ban, this does not work. The war on drugs has been lost from the start. The public fear is: “Well, if not forbidden, this is how many people will use it! Oh my God!" ... "Forbidden" does not mean "does not exist." They use it. Millions of people use "drugs" around the world, despite the ban. "But if we allow it, then they will start using marijuyana even more!" Oh really? See how society fights tobacco. Banned? Each kiosk sells cigarettes. It is not difficult for children to get cigarettes. And just tell me that tobacco is not dangerous or addictive. They are struggling with it enlightening people. Here are medical studies, here are the facts. It is harmful. This entails sad consequences. You all know, then decide for yourself. And what, all people smoke tobacco?
